Umbrella Valves
Elastomer valves for one-way opening, backflow control, and pressure relief in fluid or air passages.
- One-way elastomer valve
- Seat-matched geometry
- Media-driven material choice

Product overview
Understand the Product Before Selecting a Specification
ouning supplies umbrella valves for one-way opening, backflow control, and pressure relief in fluid or air passages. Stem diameter, head geometry, opening pressure, and material should be confirmed against the seat design and working media.
One-way elastomer valve
The umbrella head seals against a seat and opens when differential pressure overcomes the designed resistance.
Seat-matched geometry
Stem, head diameter, thickness, and hardness must match the mating hole and seat rather than a generic valve size.
Media-driven material choice
Water, air, gas, and cleaning agents determine the compound. Opening pressure should be confirmed in the actual housing.

Before requesting a quote
Selection Factors for Umbrella Valve
More complete input leads to a clearer product and material discussion.
Seat and stem dimensions
Provide hole diameter, seat geometry, head diameter, thickness, and a drawing or sample of the mating part.
Opening requirement
State the intended opening pressure or flow direction, and whether the valve must also relieve vacuum or back pressure.
Working conditions
List media, temperature, and whether the passage carries water, air, or gas.
Project quantities
Share sample quantity, order quantity, hardness, and color if the part is visible in the assembly.
Project workflow
A Practical Review Process
The steps remain clear whether you are identifying a standard part or developing a custom specification.
- 01
Define
Share the product, drawing, dimensions, service conditions, and quantities.
- 02
Confirm
Align the material, hardness, tolerances, tooling, samples, and documentation.
- 03
Validate
Review samples and complete the application-specific approval process.
- 04
Supply
Maintain confirmed specifications and identification for repeat requirements.
Questions & answers
Umbrella Valve Questions
Common questions about selecting and requesting Umbrella Valves.
How is opening pressure set?
Opening behavior depends on head geometry, thickness, hardness, and the mating seat. Send the housing details and the target opening condition with the inquiry.
Can you match an existing umbrella valve?
Yes. A sample plus measured stem and head dimensions, or a drawing, is a useful starting point.
Which material should I specify?
NBR, EPDM, and silicone are commonly reviewed. The choice depends on media, temperature, and required flexibility.
