1 3 WAY (3/2) POPPET VALVES FOR AIR AND VACUUM SERVICE SOLENOID OR AIR ACTUATED BROCHURE N-223

2 HERION S HIGH PERFORMANCE POPPET VALVES For those applications requiring high Cv, fast response times, large exhaust capacity, and a valve that is dirt tolerant - poppet valves offer an excellent solution. HERION offers a complete series of Inline Poppet s - 3/2 (3 way, 2 position) solenoid and air-actuated in port sizes from /2 to 2 NPT. Standard models include solenoid actuated valves with internal air pilot, and solenoid actuated valves with external air pilot supply, and valves with air actuation. Note: Also available in a 4/2 (4 way, 2 position) version. See Brochure N-223A. HERION POPPET VALVE FEATURES Operates with or without lubrication Long life Exceptionally long pilot valve life Extremely fast response time Excellent repeatability High flow Easy to service Bubble tight shut-off Quick exhaust feature (sizes /4 and larger) Light weight aluminum body High reliability backed by worldwide service Slip on coil design readily accepts explosion proof solenoids designed to meet CENELEC and North American NEC codes. APPLICATIONS Large cylinders Clutches and brakes (except on mechanical power presses where double valves are required). Air bags Air-oil boosters Emergency exhausting of air lines Left: Right: Poppet s 3/2 solenoid valve normally closed, normally open air or vacuum service /2 to 2 NPT.

(2) Pilot air pressure must be at least 60 psig and a minimum of psig greater than pressure at port No.. For vacuum service, vaccum is applied at Port No.. (3) Actuating air pressure must be equal to or greater than system (working) pressure at port No. and a minimum of psig. STANDARD SOLENOID NUMBER 080 Specifications: The connector conforms to ISO 40 and the combination solenoid / connector meets the classification NEMA 4. All HERION solenoids are rated for 0% duty cycle complying to insulation class 5ºF (Class F). Features: The solenoids are attached to the valve with a solenoid retaining nut. The coil of the solenoid is a pressure molded encapsulation. The electrical connection is made through three prongs (2 power, ground) which attach to the mating connector with one screw. Solenoids are stocked for 24 VDC and VAC 60 HZ Order Order No. Solenoid N N N Order No. Solenoid Order No. Solenoid Number CONNECTOR Standard cable clamp type connectors are included with the soleoid. Optional connectors may be selected from the following table: Standard Optional Connector Part Numbers Solenoid Cable Lighted - Cable Clamp Series Clamp /2 NPT 24VAC DC VAC 2 VAC Power Connection DC - 6 W AC - VA Inrush, 27 VA Holding 3

4 INTERNAL AIR VERSUS EXTERNAL AIR PILOT The pilot valve requires an air supply, in turn the pilot valve delivers the air to operate the main valve. This pilot air is normally taken from the inlet supply pressure at port number one. There are times when it may be necessary or desirable to use an external source for the pilot air. SOME REASONS FOR USING AN EXTERNAL PILOT SUPPLY. s on vacuum service - the pilot air must be a positive pressure. 2. Inlet pressure drops below the minimum psig required for internal pilot supply. 3. The air supply to the valve may contain particles of a size that could safely pass through the main valve but might block the smaller passages in the pilot valve. CHANGING FROM INTERNAL TO EXTERNAL PILOT AIR (field conversion). For ½ to valves the 4 screws holding the pilot valve assembly are removed. The pilot valve is rotated 80º and reinstalled. Refer to Fig For ¼ to 2 valves the pilot valve assembly is removed, but it is not rotated. Install a threaded screw (M8 x 6mm long) in the tapped hole and seal it with a thread sealant. See part # 2 in Fig.#. The plug shown as part # 7 in figures 3. # 2, # 3, # 5 and # 6 must be removed. The plug hole is tapped with G ¼ pipe threads. It requires an adapter when converted to ¼ NPT threads to connect the external air supply. This screw and adapter are available from HERION. When the valve is ordered by the external pilot part number the adapter and screw will have been assembled.
