Reliable Solution for Ensuring Stable Upstream Pressure: SS316 Direct Acting PSV

The RFT/RFF is a direct-acting Pressure Sustaining Valve (PSV) designed to maintain a set upstream pressure. Its back-pressure chamber controls the valve gate for quick and precise adjustments. The gate stays closed during normal operation and opens only when upstream pressure rises above the set-point, closing again as pressure drops to keep the system stable.

Frequently Asked Questions (FAQ) about Direct Acting Pressure Sustaining Valve

Q1: How does a Direct Acting Pressure Sustaining Valve work?

The back-pressure chamber directly controls the valve gate. When upstream pressure exceeds the setpoint, the valve opens to release excess pressure; when pressure is below the setpoint, the valve remains closed.

Q2: When should I use a Pressure Sustaining Valve instead of a Pressure Reducing Valve?

Use a pressure sustaining valve when you need to prevent upstream pressure from exceeding a setpoint, protecting equipment and avoiding overpressure. A pressure reducing valve, in contrast, reduces downstream pressure to a desired level regardless of upstream pressure.
