EP Series

Pilot Operated Relief Valves, designed to provide precise pressure sensing even in the face of minor tank pressure fluctuations. These valves spring into action when the differential pressure across the main valve diaphragm is at its minimum. They are specifically tailored for low-pressure settings in emergency relief situations. Our relief system relies on external pressure, utilizing Nitrogen gas to ensure unparalleled accuracy in low-pressure set points.

  • Accuracy:
    Precise set point adjustment with high resolution and accurate control. Very high capacity for small build up.
  • Tight Shut Off Capability:
    These valves give much better shut off, as compared to weight loaded valves, particularly tank pressure near to set pressure. Tight shut off prevents vapour losses.
  • Easy to Maintain:
    Robust design with minimum number of moving parts, actuator internals, valve disc & trim parts can be replaced without removing the valve from pipeline.
  • Tamper Resistant:
    An adjusting screw lock nut with protective CAP is standard to discourage tempering with pressure.
  • Economy Labor Saving Installation :
    Inter connection to pilot can be provided duly tube from main regulator body, thus required no pilot supply line tubing on standard installations.
  • Body Size & Connections:
    Flanged Sizes: 2″x3″, 3″x4″, 4″x6″, 6″x8″, 8″x10″, 10″x12″ (Higher size on request)
