2 Lever cting Design 25 series 25-*, 25-5* & 25-7 FETURES: Designed for multi-poise mounting... Self-aligning valve with lever action for dead end lockup... Durable, corrosion-resistant construction... High performance type for pounds to inches reduction... vailable in six pipe sizes from /8" to 1-1/2"... ENEFITS: Ease of installation... Longer life, less maintenance... May be used for both 2 psi and 5 psi corrugated stainless steel tubing (SST) systems. Precise regulation from pilot flows to full regulator capacity... Meets many utility specifications. The 25 Series is a pounds to inches regulator, meeting utility specifications. The 25 Series regulator is for use on residential, commercial, and industrial applications where adequate inlet pressures are available. They are a high performance type regulator and can be used as a single stage regulator - reducing pounds pressure to normal burner pressure. They can also be used as a line regulator on equipment already fitted with an appliance regulator. The 25- and 25-5 models are S certified and widely accepted with 2 psig and 5 psig house piping systems. In fact, the entire concept (using semi-rigid copper or flexible stainless steel tubing) would not have been possible without the development of the compact 25 series regulators. The 25-7, designed especially for the growing segment of electronic ignition equipment, permits the utilization of greater capacities without sacrificing performance. ll 25 Series models are also certified through DVGW to European EN 88. To deliver positive dead-end lock up, the 25 Series feature a high leverage valve linkage assembly. Lockup pressure can vary with the speed of the solenoid valve and its location. The regulators are capable of precise regulating control from full flow down to pilot flows. s an optional accessory, the 25- and 25-5 offer automatic vent limiting devices. The 1209 and 129 vent limiters eliminate the need to run vent piping to a safe area - in the event of a diaphragm rupture, gas escapement is limited to within the NSI/S standards level. NOTE: Vent limiters are designed for use indoors and in spaces where limiting the amount of gas escapement due to diaphragm failure is critical. Vent limiters are not to be used outdoors if they are exposed to the environment. 115 vent protector is available for outdoor use when vent protection is required. The 25 Series regulators are Maxitrol-tested for inlet pressures up to 10 psi (S certified for 2 psi and 5 psi). With the 1209 or 129 installed, maximum inlet pressure is 2 psi (LP) and 5 psi (natural). Inlet pressures exceeding 2 psi (LP), or 5 psi (natural) require a vent line. The self-aligning valve is made of nitrile rubber. Housings are durable aluminum die castings and all internal parts are carefully selected and corrosion resistant. The diaphragms are of high quality supported synthetic rubber compounds. The 25 Series regulators are suitable for multi-poise mounting. ut when using the vent limiting device, the regulator (25-, 25-5) must be mounted in a horizontal upright position. Install the regulator properly with gas flowing as indicated by the arrow on the casting. These regulators provide no downstream over-pressure protection in the event of failure. t supply pressures in excess of 2 psi they should not be used unless downstream appliance controls are rated for supply pressure or protected by some other means. onsult Maxitrol ompany for additional assistance. 2008, Maxitrol ompany, ll Rights Reserved 2 * S design certified

This means there will be 2 psi at the inlet of the regulator under no flow conditions, and 1/2 psi at the regulator inlet under maximum flow conditions. To select a 25 series appliance regulator of ample flow - one must know: 1. vailable inlet pressure (maximum static/minimum operating). 2. Desired outlet pressure.. Required maximum flow rate. 4. Pipe size. Example: To select a 25 series regulator of ample capacity to handle flow... KNOWN: Desired flow rate 145 FH; pipe size 1/2"; operating inlet pressure 2 psi; outlet pressure 7" w.c.; lockup required. SOLUTION: heck pressure drop chart above - the 25-'s pressure drop at a flow rate of 145 FH is 7" w.c. - well below the available differential of 1.75 psi. The 25- (1/2") used with a 4" to 12" spring, set at 7", is the correct regulator to use for this application. Pressure Drop ( P) 2008, Maxitrol ompany, ll Rights Reserved

The new line pressure regulator standard - NSI Z21.80 lthough Maxitrol's 25 Series are certified (NSI Z21.18) as appliance regulators (see bulletin 25LVR_MS_EN), in the past they have often been used as line pressure regulators. Until very recently, there was no standard for line pressure regulators. Z21.80 is the new NSI standard for line pressure regulators, intended for application in natural gas piping systems. Maxitrol's new 25 Series L-models are S certified (Z21.80) for 2-psi inlet pressure, with the 7 to 11 (inches w.c. outlet) spring. The L-models are lass 1, pounds to inches regulators, meeting utility specifications, for use on 2-psi piping systems such as SST (corrugated stainless steel) or semi-rigid copper tubing. The regulators are a high performance type - reducing pounds pressure to a level within the appliance's operating supply range. The line regulator is located upstream of equipment already fitted with an appliance regulator. The entire 2-psi system concept would not have been possible without the development of the compact 25 Series regulator. s optional accessories, the 25-L and 25-5L offer an automatic vent limiting device. The 1209 or 129 vent limiter eliminates the need to run vent piping to an outside area - in the event of a diaphragm rupture, gas escapement is limited to within the NSI standards level. The 25 Series are suitable for multi-poise mounting. ut when using a vent limiting device, the regulator must be mounted in a horizontal upright position.

The self-aligning valve is made of nitrile rubber. Housings are durable aluminum die castings and all internal parts are carefully selected and corrosion resistant. The diaphragms are of high quality supported synthetic rubber compounds. The regulator is certified for inlet pressures up to 2 psi. Over-pressure protection is not required for supply pressures up to 2-psi. These regulators provide no downstream over-pressure protection in the event of failure. t supply pressures in excess of 2 psi, the new NSI Z21.80 line regulator standard requires means approved and tested with the regulator to limit the downstream pressure to 2-psi maximum, in the event of regulator failure. onsult Maxitrol ompany for assistance.

Until very recently, there was no standard for line pressure regulators. Z21.80 is the new NSI standard for line pressure regulators, intended for application in natural gas piping systems. s of May 1, 2002, S requires that all line pressure regulators above 2-psi must leave the factory pre-assembled and leak tested. t supply pressures in excess of 2-psi, the new line regulator standard requires a means (an over-pressure protection device / OPD) approved and tested with the regulator to limit the downstream pressure to 2-psi maximum, in the event of regulator failure. Line pressure regulators with separate overpressure protection devices shall be factory preassembled, and supplied to the field as a unit. Maxitrol-built OPDs provide the required downstream over-pressure protection. s optional accessories, the regulators and OPDs offer an automatic vent limiting device. The 1209 or 129 vent limiters eliminate the need to run vent piping to an outside area - in the event of a diaphragm rupture, gas escapement is limited to within the NSI standards level. The 25 Series are suitable for limited horizontal mounting (less than or equal to 90 from upright) - but when using a vent limiting device, the regulator must be mounted in a horizontal upright position for best performance. Install the regulator properly with gas flowing as indicated by the arrow on the casting. To deliver positive dead-end lock up, the 25 Series feature a high leverage valve linkage assembly. Lockup pressure can vary with the speed of the solenoid valve and its location. The regulators are capable of precise regulating control from full flow down to pilot flows. The self-aligning valve is made of nitrile rubber. Housings are durable aluminum die castings and all internal parts are carefully selected and corrosion resistant. The diaphragms are of high quality supported synthetic rubber compounds. The regulator with OPD is certified for inlet pressures up to 5-psi, and can withstand emergency exposure inlet pressure up to 65-psi. The regulator alone provides no downstream over-pressure protection in the event of failure. Other 25 Series regulators will continue to be available as S certified appliance regulators, as well as noncertified models for up to 10-psi inlet pressure (see bulletin 25LVR_MS_EN). NOTE: Immediately after installation and prior to operating any appliance: It is important to check the preassembled pipe connection between the regulator and OPD for leakage. Even though the Maxitrol 5 psi line regulator with OPD is shipped as an assembly, installation of the assembly can result in turning (tightening or loosening) of the preassembled connection.

Outlet Pressure Range (all models): ertified spring inches w.c. 25-5L600 SIZING INSTRUTIONS To select a line regulator of ample flow - one must know: 1. vailable inlet pressure (maximum static/minimum operating). 2. Desired outlet pressure.. Required maximum capacity (total load, all appliances combined), and maximum individual load. 4. Pipe size. Example: To select a line regulator with OPD of ample capacity to handle flow... KNOWN:. Required: 1/2 NPT line regulator with OPD, outlet pressure of 7 w.c., with a static pressure of 5-psi, and a minimum operating inlet pressure of /4 psi.. ombined tu rating of all appliances to be served by the regulator: 145,000 tu/hr.. Largest single appliance s tu rating: 90,000 tu/hr. SOLUTION:. In the apacities table (page ), locate [25-L47 (1/2 ) = 125 FH, 25-L48 (1/2 ) = 200 FH, 25-5L48 (1/2 ) = 25 FH].. The total tu load requirement cannot exceed the equivalent FH result from step-. The combined 145,000 tu/hr requirement exceeds the 25-L47 (1/2 ) capacity, but is less than that of the 25-L48 (1/2 ) and 25-5L48 (1/2 ).. The 90,000 tu/hr single largest appliance rating is below the 25-L48 maximum individual load capacity of 200,000 tu/hr. D. The 25-L48 is the smallest acceptable (1/2 ) line regulator with OPD for this application.
