Solenoid Valves for Electropneumatically Actuated Bellows and Diaphragm Valves - SWAGELOK - #1

Text version of the page

Warning: . Following a significant loss of actuator air pressure, the ball valve will return to the solenoid de-energized position, whether the solenoid is energized or not. . Following a significant loss of actuator air pressure, the ball valve may cycle. Solenoid Valves For Electropneumatically Actuated Ball Valves Features An electropneumatically actuated ball valve-actuator assembly consists of:  a Swagelok ball valve  a Swagelok pneumatic actuator  a solenoid valve for use with:  a spring-return pneumatic actuator (3-way, 2-position) or  double-acting pneumatic actuator (4-way, 2-position). Technical Data Actuation Pressure 25. to 150 psig (1.7 to 10.3 bar) . 25 psig (1.7 bar) is the minimum requirement for the solenoid valve. See valve product catalogs for minimum actuator pressure requirements. Temperature Range 0 to 120°F (–17 to 48°C) Electrical Data  NEMA type 4 solenoid enclosure  General-purpose, class A coil, continuous duty, encapsulated  18 AWG lead wires, 18 in. (46 cm) long  1/2 in. female NPS electrical conduit connection (enclosure)  1/4 in. female NPT pneumatic ports Materials of Construction www.swagelok.com Zinc-plated alloy steel Component Material Solenoid body, spool, poppet Aluminum Spool O-ring Buna N Fasteners Solenoid valve Initial position Actuator/ Solenoid Mode Solenoid Energized Solenoid De-energized Valve Position Normally closed spring-return actuator/ solenoid energized to open 90°. Normally open spring-return actuator/ solenoid energized to close 90°. Spring-return actuator/solenoid energized to switch 180°. Double-acting actuator/solenoid energized to open 90°. Double-acting actuator/solenoid energized to close 90°. Double-acting actuator/solenoid energized to switch 180°. Open Open Open Open Closed Closed Closed Closed Opposite port Opposite port Initial position Operating Modes Air pressure is required to cycle the ball valve. See valve product catalogs for minimum actuator pressure requirements. Solenoid valves are assembled with brass Swagelok® fittings. Copper tubing is used with double-acting actuators.
