Mushroom Valve

Mushroom Valve & Umbrella Shape Check Valve, also known as umbrella valve, as one kinds of silicone rubber one-way valves & intake and exhaust valves, which elastomeric diaphragm shape in aim to allow air & liquid flow in one direction and backflow in the opposite direction, working like rubber flapper valves & poppet valves.

Mushroom Valve

Mushroom Valve & Mushroom Check Valvealso known as umbrella valve, as one kinds of rubber one-way valves & intake and exhaust valves, which elastomeric diaphragm shape in aim to allow air & liquid flow in one direction and  backflow in the opposite direction, working like rubber flapper valves & poppet valves.

Mushroom Check 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. 

Mushroom Shaped Check Valve

Mushroom Valves Main Materials:

  • Silicone (VMQ)

  • Fluorosilicone Rubber (FVMQ)

  • EPDM

  • HNBR 

  • FKM

  • Nitrile Rubber 

  • Neoprene Rubber 

Mushroom Valve's Materials Choice, Hardness Limits and Packaging Demands

  • Mushroom Check Valves Materials should choose lower compression set and high elastic elastomers (tensile strength).

    Silicone Umbrella Valve, the best made from 100% high elasticity.

    Notes:The mechanical and physical properties of fluoro silicone rubber are very similar to silicone. 

    Fluorosilicone rubber & FVMQ is noted for its resistance to fluro organic solvents and petroleum based fluid.

    Most of automotive & machine's mushroom valves is made from fluorosilicone materials.

  • Mushroom Check Valves Hardness, generally less 55 Shore A which mainly depends on umbrella hook designs

  • Mushroom Valve Packaging: PE Bag with air inside in aim to prevent deformation & out of shape

Mushroom Check Valve Design Guide

Umbrella Valves have three key designs & sizes and two key diaphragmatic surface demands: 

  • Mushroom Shaped Diameter: bigger than one-way valve holes

  • Hook Height: same to plastic & metal panel's height

  • Stem Diameter: same or maller than assembly holes

  • Outside Diaphragmatic Surface: EDM process or texture surface for dust proof

  • Inside Diaphragmatic Ring Edge Surface: Polish or high-polishing for sealing function

Our Advantage for producing Mushroom Valve

  • Minimize the parting line (joint line) to make beautiful surface

  • Do matte smooth coating on Ear Plug's surface, which can  comfortable contact and anti-dust effect.

  • Adopt FDA and Medical grade material during the whole manufacturing procedure, including silicone material, pigment (for customized color) and release agent.

  • Process mold tool by precision Mirror surface EDM machine, which make silicone ear plugs higher precision so as to produce exactly suitable dimension for individual's ears.

  • (Notes: Mirror surface EDM machine processing is usually used for high precision silicone rubber compression mold tool, LSR(liquid silicone rubber) or Plastic Injection Mold, especially the precise processing on some complicated aspherical surface of mold base, which makes components higher quality, more precise dimension and more exact dimensions for your applications)
