The VCP Pressure Relief Valves consist of a cylindrical shaped stainless steel casing with bottom flange to connect to the silo, an inner negative pressure disc held in position by a central spring rod, an outer positive pressure steel ring kept in position by three spring rods, and a weather protection cover.

Almost any application involving the movement of powders and granules, filtration of liquids or dust and fume collection can be serviced by Filquip. Read more

Through an interplay of pressure on both sides of the membrane fitted inside the valve a perfect pressure balance is achieved. In the event of excess pressure the membrane enables air from inside the silo to flow out into the atmosphere, whereas in case of suction vacuum pressure opens the membrane to the atmosphere to allow air in to prevent silo collapse.

Filquip can supply a tailored silo overfill protection system to suit any system, to prevent dangerous over pressurisation and over filling, while eliminating dust emissions.

Filquip supply WAM VCP-D spring loaded silo pressure relief valves made from polymer are built to handle sudden excess or suction pressures that can develop in the silo, hopper or bin.

Preset springs keep the valve closed when the pressure inside the silo remains within the preset limits.  Once the pressure exceeds the preset value the outer ring is pushed up and pressure can escape. In the event of vacuum pressure the spring is compressed and allows the inner disc to drop. The air entering the silo from outside ensures rapid pressure balancing and before the spring pushes the inner disc back up into “closed” position.

Filquip supply WAM VHS membrane silo pressure relief valves to provide a safety net when abnormal pressure conditions endanger the silo structure.

The WAM VHS and VCP Silo Pressure relief valves provide a safety net when abnormal pressure conditions endanger the silo structure. With hundreds of thousands installed worldwide, WAM Pressure Relief Valves are the standardised reliable solution for almost any silo application.

Filquip supply WAM VCP spring loaded silo pressure relief valves to handle sudden excess or suction pressures that can develop in the silo, hopper or bin.

Filquip has been providing Hopper and Silo Filling Systems including Silo pressure relief valves for over 20 years for all types of powders and granular materials.

The VHS Pressure Relief Valves consist of a cylindrical shaped stainless steel body with clamped connection spigot to the silo, an exhaust outlet spout for duct to ground connection, an elastic membrane which is able to re-establish pressure balance instantaneously, a counterweight kit to keep the valve closed under normal conditions, and a weather protection cover.

The VCP-D Pressure Relief Valves consist of a cylindrical casing made from engineered polymer with bottom flange to connect to the silo, an inner negative pressure disc held in position by a central spring rod, an outer positive pressure steel ring kept in position by three spring rods, and a weather protection cover.

Filquip supply WAM VHS-C Polymer membrane silo pressure relief valves to ensure the filling of a silo does not allow abnormal pressure conditions to endanger the silo structure.

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