As its predecessor, the VHS-type, the VHS-C Pressure Relief Valve is the last safety net when abnormal pressure conditions endanger the silo structure. This is why sudden excess or suction pressure inside the silo has to be dealt with instantly. Even though ideally a VHS-C Pressure Relief Valve should never have to go into action, it must be efficient and reliable if needed.
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.
