One Way Rubber Sealing Valves

One-Way Rubber Sealing Valve Materials

Custom Gasket Mfg. provides one-way sealing valves such as flapper valves, umbrella valves, and duckbill valves. Additionally, we work closely with our customers to create custom rubber sealing valves to meet their needs, industry standards and to withstand harsh, chemical conditions. The rubber molding tolerances for one-way rubber valves are complaint with rubber molding industry standard RMA A2 Precision tolerances.

Custom Gasket’s industry expertise will point you in the right direction by assisting in your rubber valve design for your flow parameters.

Flapper Valves, Umbrella Valves, Duckbill Valves and Custom Rubber Check Valves

One-way sealing valves are used to facilitate a unidirectional flow of fluid. Depending upon the application this either causes a forward flow or prevents backflow in a device. Our flapper, umbrella, duckbill and custom valves are produced from a wide variety of rubber compounds, including medical and food-grade silicone and hydrocarbon-resistant fluorosilicone rubber in order to handle a broad range of tolerances and temperatures.

All one-way rubber sealing valves allow fluid, either a liquid or a gas, to flow through it in only one direction. The design and structure of one-way check valves make them widely applicable in pressured fluid environments. The elastomeric compound offers itself to be low-maintenance, rust-free, and highly responsive to very subtle pressure changes. Flapper Valves accomplish this by containing a hinged flap or disk that swings in one direction only. Umbrella Valves feature a ball or rounded shaped end which snaps easily into a mating plate or receptacle. Duckbill Valves allow positive pressure to open the valve and negative pressure to close off flow. Our custom one-way rubber valves offer a solution to unconventional unidirectional flow requirements.
