Benefits and features

Fixed overpressure and blow-down according ASME Sec. I with no rings hence no requirement for adjustment.

It guarantees a stable position of the disc by mechanical lift stop at full lift. The optimized disc spindle connection o‚ers high seat tightness. The forged inlet nozzle is available with welding connection or flanged connection. Special disk spring design for high pressures and large orifice diameters is proven.

The EPV 9 is full nozzle design and the inlet pressure contained by a forged solid part. The cast outlet body is charged by the reliefed pressure only. The valve function is stable up to 25% built up to backpressure.

This product is used for the following applications: power plants and industrial steam generation; steam applications in the petrochemical industry; steam boilers; super heaters and process steam systems.
