Pilot Operated Relief Valve

The Groth Model 16F-TPO-O offers reliable low-pressure protection in compliance with
API 2000 standards for Pilot Operated Relief Valves. Its design prevents fugitive
emissions, complies with API 2000, and conserves stored product. With a rated flow at
10% overpressure, it enables operation closer to the tank MAWP, expanding the process
operating range and reducing the requirement for excessive overpressure. This not only saves
product but also enhances profitability. The valve employs film seat sealing technology
for superior sealing and offers flexibility in terms of snap or modulating action.

• Ease of precision settings
• Main valve remains tight to set pressure.
• Full open at 10% overpressure
• Modulating action conserves product since valve opening is proportional to overpressure
• Noise is reduced since the valve only opens fully when required
• Soft seats seal tight to conserve product and minimize valve wear which improves reliability
