Cylinders and other air operated devices are eased into normal operating positions, reducing the possibility of equipment damage and hazards to the user. Blocks inlet air and exhausts downstream air when pilot signal is removed or when the optional manual lockout slide is closed Optional manual slide can be padlocked in closed position Solenoid pilot or air pilot operation Designed for use in start-up and shutdown of equipment. Fluid: Compressed air, neutral gases NOTE: Contact technical support for use with other media. Maximum pressure solenoid operated: Dependent on solenoid rating [must not exceed 150 psig (10 bar)] Maximum pressure pilot operated: 150 psig (10 bar) max. Minimum operating pressure: 44 psig (3 bar) Operating temperature solenoid operated: Dependent on solenoid rating [must be within range 0°* to 150°F (-20°* to 65°C)] (72) [must be within range 0°* to 175°F (-20°* to 80°C)] (74) Materials Body: zinc alloy (72) aluminum (74) Elastomers: synthetic materials Filter discs: sintered plastic Internal components: brass/steel Technical data
