IER Fujikura Umbrella Check Valves are designed to be a normally-closed valve, allowing flow in one direction. The valve opens and closes at present pressures for each rubber material option. We offer a wide range of pre-engineered sizes and can custom design a valve to meet your specific application needs.
Typical applications for the valves include fluid control, dispensing, emission control, pumps and medical equipment.
The valves are highly responsive to minor pressure changes and offer precise metering and control of fluids, while delivering repeatable, stable flow during operation. The valves seal to a leak-free, air-tight closure.
Molded material options:
• Nitrile,NBR
• Fluorosilicone,FVMQ
• Fluorocarbon,FKM
• Silicone,VMQ
• Ethylene Propylene,EPDM

I am currently using an EPDM Bunsen valve in my battery to act as a one-way >3psi burp valve. When I consider the height of the required chimney and the valve body, the overall height of the valve unit is ~6mm above my cover. I would like to reduce the height requirements of the valve by using an umbrella valve. I have space inside the battery to accommodate the stem of the umbrella.
So my specs would be…
~3psi burp pressure
>1psi positive reclosure seal
EPDM material
The smaller diameter the better
Any color will work
Please let me know what you think and send me some test samples if they are available.
