5 inch Pilot Operated Pressure Relief Valve, DN125

A pressure relief valve with DN125 nominal diameter, pressure rating is PN16, the shell test pressure is 2.4 MPa. The pressure reducing valve automatically opens at a set pressure and provides proportional and slow pressure relief.

Features

• Pilot-operated valves for limiting a system pressure
• Operation using proportional solenoid
• Maximum pressure limitation
• Valve and control electronics from a single source
• Little manufacturing tolerance of the command value
• Pressure characteristic curve

Pressure Relief Valve Application

Tips: What is the difference between a direct and pilot-operated relief valve?

The main difference between direct-acting and pilot solenoids is that direct-acting solenoid valves have a direct connection with the opening and closing armature, whereas pilot-operated valves employ the use of the process fluid to assist in piloting the operation of the valve.
