EP Series

Pilot operated emergency pressure relief valve for precise low-pressure tank relief with nitrogen gas external loading.

The EP Series are pilot operated relief valves designed for precise pressure sensing even in the face of minor tank pressure fluctuations. These valves are specifically tailored for low-pressure settings in emergency relief situations. The relief system relies on external pressure, utilizing Nitrogen gas to ensure unparalleled accuracy in low-pressure set points, with much better shut-off than weight-loaded valves.

Key Features

• Precise Set Point Accuracy — High resolution adjustment with very high capacity for small pressure buildup.
• Superior Tight Shut-Off — Far better shut-off than weight-loaded valves when tank pressure is near set point.
• Easy Field Maintenance — Robust design — actuator internals and trim replaceable without pipeline removal.
• Tamper Resistant — Adjusting screw lock nut with protective cap standard on all units.
• Economy Installation — Pilot interconnection pre-tubed from main body, eliminating site tubing runs.

Applications

• Storage tank low-pressure relief (de-padding)
• Petrochemical storage tanks
• Chemical bulk liquid storage
• LNG/LPG storage vessels
