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.

In fact, there is no precise definition for pure water. Typically, it refers to water with an electric resistivity ratio of 0.1 to 1.5 MΩcm. The fewer impurities water has, the higher its electric resistivity ratio, and the lower its conductivity.

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.

Continued use of a boiler or humidifier with water containing a high volume of impurities leads to a buildup of impurities (such as scale) inside the boiler or humidifier. This causes pipe blockages and adversely affects heat transfer, resulting in decreased equipment functionality.

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.

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.

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.

In pure water containing almost no impurities, the water properties are manifested even more clearly and its dissolving power becomes even stronger.

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.

Water for cleaning is as familiar to us as drinking water. We can easily think of numerous ways we use water in daily life—washing our hands and faces, doing laundry, and mopping floors are just a few.

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.

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.

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.

Ultrapure water refers to high-purity water where river water or water for industrial use has been made as close as possible to pure H2O by combining water purification component technologies. The water is processed to an ultra-high level of purity by removing not only solid substances and salts, but also gas dissolved in the water. Organo’s industry-leading analysis technology is also essential in the manufacture of ultrapure water.

Pure water refers to highly pure water with few impurities. It indicates a state in which almost all salts and organic matter have been removed, and depending on the method employed to remove impurities, the water is referred to as desalinated water (water in which the salts are removed using ion exchange resins or other agents), RO (reverse osmosis) water (water filtered through a reverse osmosis membrane), or distilled water (water derived from steam that has been cooled and condensed back into liquid).

There are many wine enthusiasts in Japan as well. Wine glasses, which play an important role in the enjoyment of wine, come in various shapes that enhance the wine’s aroma or taste. However, it takes a lot of effort to properly care for wine glasses. If you don’t take proper care, you can ruin the experience.

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.

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

Even colorless, transparent water contains a variety of components. For example, if a 50 m swimming pool were filled with tap water, it would contain the equivalent of several metal drums full of impurities.

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.

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
