Double Valves with Dual Monitoring (CSA Z142) - 1

Product Information SERPAR® Double Valves with Dual Monitoring Includes Both L-G and E-P Monitors – Sizes 8, 12, & 30 STANDARD SPECIFICATIONS Pilot Solenoid: Two, rated for continuous duty. Standard Voltages: 100-110 volts 50 Hz; 100-120 volts 60 Hz; 24 volts D.C. Power Consumption: Each solenoid, 87 VA inrush, 30 VA holding on 50 or 60 Hz; 14 watts on D.C. Reset Solenoid (E-P): Rated for intermittent duty. Standard Voltages: Same as above for pilot solenoids. Electrical Connections: Terminal Strip Ambient Temperature: 40° to 120° F (4° to 50° C). Media Temperature: 40° to 175° F (4° to 80° C). Flow Media: Filtered air; 5 micron recommended. Inlet Pressure: 30 to 125 psig (2 to 8.5 bar). Reset Pressure (L-G): 60 psig (4 bar) minimum. ROSS’ new SERPAR ® Double Valves with Dual Monitoring provide the reliability and durability you have come to expect from ROSS since the introduction of the rst monitored double valves for mechanical power press safety in 1954. These dual-monitored valves are based on the proven technology of the SERPAR® family of double valves, adding independent signal sources and redundant monitoring to meet CSA Z142 (Canadian Standards Association) requirements for safety circuit performance. Incorporating both ROSS’ L-G and E-P monitoring systems provides redundancy in monitoring through two separate, dissimilar monitors. The actuating solenoids are wired independently through a doublepole, double-throw switch in the E-P monitor. These new SERPAR® Double Valves with Dual Monitoring are available in sizes 8, 12, and 30, with port sizes ranging from 1/2 to 2. The valves mount inline via removable anges, and are available with or without manual overrides. FEATURES: • SERPAR® technology • PACER® solenoid pilots • Dual monitoring – E-P & L-G • Designed to enable • DPDT (double-pole, compliance with current safety regulations double-throw) switch • 3/2 normally closed function • Non-clogging Silencer • Rugged poppet technology
