What is An Umbrella Valve?
Umbrella valve allows fluid freely to go through from one direction to prevent reverse fluid leakage, it is suitable for high precision requirements and functional working environment.
By the design of the pressure range, the umbrella valve may be automatically opened and closed, our umbrella valve can work effectively in the pressure range from 0.5KPA to 60KPA.Compared with the traditional anti-reverse valve, the valve does not require a lot of parts to cooperate the completion of the work, its installation is very simple, the required installation space is much small, the cost is the best option.
Umbrella valves are elastomeric valve components that have a diaphragm shaped sealing disk or an umbrella shape if you like. These elastomeric components are used as sealing elements in backflow prevention devices or one-way valves or check valves, in vent valves or pressure relief valves and in metering valves.
When mounted in a seat, the convex diaphragm flattens out against the valve seat and absorbs a certain amount of seat irregularities and creates a certain sealing force. The umbrella valve will allow forward flow once the head pressure creates enough force to lift the convex diaphragm from the seat and so it will allow flow at a predetermined pressure in one way and prevent back flow immediately in the opposite way. Minivalve can vary the opening pressure of standard umbrella valves. Pleae ask about our capabilities. The main advantage compared to other types of valves such as spring loaded disc valves is that an umbrella valve uses its elastic material properties and its preloaded convex shape to create the sealing force against the seat and that it uses the central stem to hold the component in place so as to avoid the need for additional components such as a spring and the need for a central or circumferential disc positioner(s).
This simplifies the design of the assembly and makes the valve adaptable to minimal space, reduces the number of pieces in a valve, simplifies assembly and last but not least is very cost effective.
