Tips: What is a pilot operated pressure relief valve?

The pilot-operated pressure relief valve adjusts the flow of the medium by controlling the opening of the opening and closing parts in the valve body and reduces the pressure of the medium. Within a certain range, when the inlet pressure is constantly changing, keep the outlet pressure within the set range to protect subsequent living and production appliances.

Existing reviews of 2 inch Pilot Operated Pressure Relief Valve, DN50

Excellent performance

I installed this 2-inch pilot operated pressure relief valve on one of our pipeline sections, and it has been working very well so far. The build quality feels solid, and the PN16 rating with a 2.4 MPa shell test pressure gives a lot of confidence in demanding applications. The adjustable design makes it easy to fine-tune the system pressure, and the structure is clearly well-engineered—responsive, stable, and reliable during operation. For the price, it offers excellent performance, and it has helped our system run more smoothly and safely without any issues.
