Pressure Regulators > Upstream Pressure Regulator >> EP Series
The Pilot operated Relief Valves gives accurate pressure sense against small variation in tank pressure. This valve reacts when differential pressure across main valve diaphragm is minimum. These valves are used for Low Pressure setting in case of Emergency Relief. This relief system uses external pressure such as Nitrogen gas for highly accuracy in low pressure set point
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.
