Umbrella Check Valves for Efficient Fluid Control
Product Number: V573210100
Umbrella valves are single-component, in-line, one-way check valves that function effectively when paired with a flat seat. These valves are normally closed and are ideal for applications requiring a precisely defined low opening pressure. They offer excellent resistance to backflow leakage. By combining the valve with an appropriately designed seat, the balance between forward flow and reverse pressure resistance can be optimized.

Design Characteristics
Function
This is a small general purpose one-way umbrella check valve with a push-in designed stem fit to seat.
Working Principle
Umbrella valves consists of a dome shaped elastic valve body which provides a sealing function in the backflow direction when mounted in a seat. Opening pressure is determined by the amount preload applied to the valve body and by the skirt design. Forward flow is a function of pressure differential over the flow path cross sections and the skirt design.
Mounting Instructions
Umbrella valves can be mounted in any position. Mounting is easy and this design is push-in but pull in and other mounting designs are also available. For proper functioning the umbrella OD should have clearance with the housing assembly so as not to restrict flow.
