For valves basic size 3/4 & 1-1/4, the DPST switch is actuated whenever the valve is not in the normal home position.
Contact conditions during switch travel (0 to 6 mm).
STANDARD SPECIFICATIONS (for valves on this page): Construction: Poppet. Mounting Type: In-Line. Solenoid Pilot: AC or DC power. Rated for continuous duty. Standard Voltages: 24 volts DC; 110-120 volts AC, 50/60 Hz. Power Consumption: 87 VA inrush, 30 VA holding on 50 or 60 Hz; 14 watts on DC. Ambient Temperature: 40° to 120°F (4° to 50°C). Media Temperature: 40° to 175°F (4° to 80°C). Flow Media: Filtered air. Inlet Pressure: 40 to 150 psig (2.8 to 10.3 bar). Pilot Pressure: Must be equal to or greater than inlet pressure.
Switch Current/Voltage Max.: 2.5 A/120 volts AC. Switch Current/Voltage Min.: 50 mA/24 volts DC. NOTE: Electrical life of switch varies with conditions and voltage; rated in excess of 15 million cycles. Functional Safety Data: Category 2 PL d; B10D: Valve - 20,000,000, Switch – 2,000,000; PFHD: 2.35x10-7 ; MTTFD: 98.15 (nop: 7360); DC (obtained by monitoring safety switch status): 90%; ROSS recommends testing the switch function and sealing for load holding valves every 8 hours. Vibration/Impact Resistance: Calculated to BS EN 60068-2-27.
IMPORTANT NOTE: Please read carefully and thoroughly all of the CAUTIONS, WARNINGS on the inside back cover. Online Version Rev. 10/02/17
