Name: Membrane Pressure Relief Valves VHS-C
Brand: Wamgroup
Availability: InStock

High safety level thanks to conveyed flow and reduced emissions

Higher performance at a competitive price

Lightweight and corrosion-free

VHS-C Pressure Relief Valves – the evolution of the VHS-type – consist of a cylindrically shaped polymer body with flanged connection spigot to the silo, an exhaust outlet elbow for duct connection, an elastic membrane able to re-establish pressure balance instantaneously, a counterweight kit to keep the valve closed under normal conditions, and a weather protection cover.

Function

The counterweight-loaded VHS-C Pressure Relief Valve has one decisive advantage over WAM’s other pressure relief valve, the VCP. Due to the moment of inertia of the helical springs on the VCP-type pressure relief valve, pressure balance is re-established quickly but not instantaneously. The VHS-C, on the other hand, does the job in real time. Through an interplay of pressure on different surface areas on both sides of a membrane fitted inside the valve casing, perfect pressure balance is achieved. In the event of excess pressure this interaction enables air from inside the silo to flow back into the atmosphere, whereas in case of suction pressure the air penetrates from the atmosphere into the silo.
