Pressure Relief Valve

  • SV010


Pressure Relief Valve

Pressure Relief Valve, also called Safety Relief Valve, One Way Valve & Check Valves, is a elastic diaphragms or sealing gasket for used in pressure relief valves controller devices. 
Pressure Relief Valves include many shapes according to designs and applianc es like   umbrella valves, duckbill valves, membrane valvesdispensing valve, air control one way valve, flange valves etc.
Pressure Relief Valve
Pressure Relief Valve, its diaphragm can be used in low or high pressure systems to control or limit the air with valves. Xiamen Better Silicone Company can make compression mold tooling or liquid silicone rubber injection molding ( LSR Molding) and produce different shapes translucent elastomeric silicone rubber sealing valves & Gasket in the 0.1 mm thickness range according to customer's designs drawings, samples or ideas etc.

Pressure Relief Umbrella valve
Pressure Relief Umbrella Valvealso called pressure relief mushroom valve, can be classified by shapes like with or without hook, air controller pressure demands with different thickness diaphragm edges etc, which is mainly used in air control device like medical resuscitators, diving equipments etc. Some medical umbrella valve is also used in liquid & water controller device like diaphragm pump, toilet products, automotive fuel tanks, outlet valves etc.
Notes: Pressure Relief Umbrella valve with hook should be made of high tensile elastic silicone materials by three layer mold plates for avoid hook damage when production.
Generally, much softer, much better.

Pressure Relief Duckbill valves
Pressure Relief Duckbill Valves is one kind of non-return valvescheck valve or one way valve, which is unique and one-piece silicone rubber components that act as backflow prevention devices or check valves, and elastic lips which in aim to prevent backflow or allow forward flows.

Pressure Relief Duckbill valve is also called slit cutting valve, which need to punched by die tooling after silicone rubber compression molding or LSR injection production. This process is key to air duckbill check valves quality.

Pressure Relief  Duckbill Valve not only take full advantage of elastomeric silicone physical properties, and also need make the most of die or slitting cutting usage. Generally, duckbill valves hardness, cutting area and slit cutting technology which key to non return valve quality. Duckbill Check Valve has a wider range of application than air umbrella valves because of good 
controller functions for  air or liquid fluid .
