Type VRD Direct Acting Relief Valve
 |
|
The VRD direct acting pressure relief valve has been designed to provide accurate pressure control in systems operating at pressures up to 1380 bar (20,000 psi).
A number of seal materials are available, making the valve compatible with a wide range of process fluids.
The valve is constructed predominantly from stainless steel for use in harsh environments.
Nitrile: –20°C to +80°C.
