Double Valves with Dual Monitoring (CSA Z142)

Product catalog summary
Overview: The document provides technical specifications and features of the SERPAR® Double Valves with Dual Monitoring, designed for mechanical power press safety. These valves incorporate both L-G and E-P monitoring systems to ensure redundancy and compliance with CSA Z142 safety standards.
Specifications:
  • Pilot Solenoid: Two solenoids rated for continuous duty with standard voltages of 100-110V at 50 Hz, 100-120V at 60 Hz, and 24V DC. Power consumption is 87 VA inrush and 30 VA holding for AC, and 14 watts for DC.
  • Reset Solenoid (E-P): Rated for intermittent duty with the same voltage specifications as the pilot solenoids.
  • Temperature Range: Ambient temperature from 40° to 120°F (4° to 50°C) and media temperature from 40° to 175°F (4° to 80°C).
  • Flow Media: Filtered air with a 5-micron recommendation.
  • Inlet Pressure: 30 to 125 psig (2 to 8.5 bar).
  • Reset Pressure (L-G): Minimum of 60 psig (4 bar).
Features:
  • Dual monitoring with E-P and L-G systems.
  • DPDT (double-pole, double-throw) switch for independent wiring of solenoids.
  • 3/2 normally closed function with rugged poppet technology.
  • PACER® solenoid pilots and non-clogging silencer.
  • Compliance with current safety regulations.
Model Information: The valves are available in sizes 8, 12, and 30, with port sizes ranging from 1/2 to 2 inches. They can be mounted inline via removable flanges and are available with or without manual overrides.
Caution: The E-P reset solenoid should not be energized continuously as it is rated for intermittent duty only.
Warranty and Contact Information: Standard ROSS warranty applies. Contact details for ROSS offices worldwide are provided for customer service and technical support.

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
