Product Description

Rubber One Way Check Valve
Rubber Valves are also known as Silicone Valve, One Way Valve, Non-Return Valve, Check Valve, Air Flow Valves, which  are usually used for controlling the direction of air or fluids flow in health care, automotive, appliance or food and packaging industries, diving equipment, etc. Some common rubber valves like umbrella valve,buckbill valve, diaphragm valve, flapper valve, dispensing valve, etc. 


Umbrella Valve
Silicone Umbrella Valves, known as Mushroom Valves or Umbrella Check Valves. Rubber Umbrella Valves have round diaphragm seals & seat for air or water pressure relief and backflow controls. The stem and hooks of umbrella valve is for fixing. Umbrella valves are generally made from medical grade or food garde silicone or LSR materials. Other rubber materials like EPDM, NBR etc. are available in our company.

Duckbill Valves
Duckbill Vallve, as a elastomeric fluid-flow control components, seals or nozzles, is one type of rubber one way valves. The duckbill design aim to automatically prevent air or fluid backflow and allow forward flow.

Dispensing Slit Cutting Valves
Silicone Diapensing Valve,  also known as Slit Cutting Valve, as a elastomeric non-return valve & Check Valve in control components, which aim to automatically prevent air or fluid backflow and allow forward flow.
