1 Pressure Regulators Kosan Crisplant is able to offer regulators that may be used in different kind of applications for industrial or domestic use. Pressure regulators are necessary in order to enable the use of the stored or distributed gas for different applications, thereby ensuring the necessary reduction to fit the high for different utilizations. The information on regulators is organised in the following ranges: High Demand First Stage Regulators First Stage Regulators Industrial and Commercial Second Stage Regulators Second Stage Regulators Twin Stage Regulators Adjustable High Pressure Regulators Please bear in mind that in order to select the correct regulator size, the following information is necessary: All flow capacities in the tables are based on specific conditions. For information on capacities in different conditions, please contact us. Incorrect use or failure of regulators may cause dangerous situations such as: High than desired downstream from the regulator Leaks of gas on the regulator Lower than desired downstream from the regulator Damage or accident as consequence of the previous situations The range Kosan Crisplant is offering is complete and matches several specifications and different demands from various markets. Nevertheless, if you do not find what you need on the following pages, we kindly ask you to contact us. We will do our best to provide the best solution for your need. For proper support contact one of the KC offices closest to your location. Inlet Outlet Desired flow Type of gas

2 High Demand First Stage Regulators High demand first stage regulators are installed as the first stage regulator on gas installations as they are able to reduce the from the 1st stage to an intermediate before utilization (2nd stage). In some cases, this kind of regulators may supply the gas directly to the industrial equipment. By screwing or unscrewing the adjustment spring, or adding several spring ranges, it is possible to set the outlet of the regulator.

By screwing or unscrewing the adjustment spring, or adding several spring ranges, it is possible to set the outlet of the regulator.

3 First Stage Regulators These types of regulators are installed as the first stage regulator on LPG installations as they are able to reduce the from the tank or the cylinder (1st stage) to an intermediate before utilization (2nd stage). In some cases, this type of regulators may even supply the gas directly to the industrial equipment which should then be prepared to receive gas flow at high. Some types of regulators are adjusted from the factory without the possibility of changing the outlet, while other types can be user adjusted by screwing or unscrewing the spring. Depending on the model, regulators may have an internal relief valve or/and tap incorporated.

In some cases, this type of regulators may even supply the gas directly to the industrial equipment which should then be prepared to receive gas flow at high.

4 Industrial and Commercial Second Stage Regulators The industrial and commercial regulators are installed as the second stage regulator on a LPG installation as they are able to reduce the from an intermediate, downstream from a LPG cylinder or a LPG tank, to a utilization. Some types of regulators are adjusted from the factory without the possibility of changing the outlet, while other types can be user adjusted by screwing or unscrewing the spring. Depending on the model, regulators may have an internal relief valve or/ and tap incorporated Part Number OUTLT PRSSUR RGULATION SPRINGS Outlet colors spring Outlet colors spring HSR Outlet range spring Red 9-16 Green Yellow Blue Orange Silver Green Black Gray Orange Cadmium * Pink Black&White White * Light Blue Cadmium* Black* * - Hp models only Connections (FxF) NPT Orifice Internal Relief Valve Outlet * Pin (Bar) Yes ,38 71 (setpoint 0,69 48 xxmbar) 0, ,34 31 ¾ 1, , , , ½ , (setpoint 1, xxmbar) 0, , , (setpoint 1, xxmbar) 0, , HSR 1 1/ (setpoint 2, mbar) 1, ,69 47 * - For standard spring ** - Capacities based on outlet of 1.4 bar, for butane multiply by for Nm 3 /h of NG, multiply by 0,80 Propane** (kg/ hr) HRS HRS 74

6 Twin Stage Regulators Twin Stage Regulators are compact solutions with the availability of reducing the from LPG tanks or cylinders (1st stage) directly to utilization maintaining the advantages of a two stage regulation system. Internally, they incorporate two different reductions steps instead of only one as normal. Usually, the regulators are user tuned by screwing or unscrewing the spring. Depending on the model, regulators may have an internal relief valve or/ and tap incorporated.

7 High Pressure Industrial/Commercial Adjustable Regulators Adjustable regulators represent the best solution when it is necessary to work with a wide range of settings on the same device. Regarding the tank or cylinder, this type of regulator is able to adjust the outlet by use of a Tee handle. In order for the operator to adjust the, the regulator normally has a tap for manometer installation. The regulators mentioned below are able to work with liquid or vapor. Downstream or upstream relief valve installation is recommended. Care must be taken to prevent re-liquification of propane at normal temperatures by heat tracing or other effective means.
