Check Valves
Economic price, sold in bulk. Because the Original MPC Check Valves are manufactured in the U.S., high volume requirements are not a problem. We package our check valves in quantities large enough to justify a substantial price break in piece price & shipping charges over the small order distributor. To help keep our prices low, we manufacture the most popular sizes in the most popular materials.

Recommended for systems between 1/2 psi minimum back pressure and 15 psi max back pressure. The Original MPC Check Valve's exceptionally reliable performance is due to the interior design. It functions by sealing against a concave surface, we recommend at least one half PSI of differential/back pressure forcing the flat diaphragm material to conform to the sealing surface.

Simple, compact, three-piece design that is light weight. The Original MPC Check Valves are molded and assembled with the innovative expertise that can only be gained by over 30 years of experience in making them.

Functional reliability from -70 to 210 degrees Fahrenheit. Our materials were chosen for their functional reliability in the extreme environmental elements. Check with Sales regarding the details of the materials of the check valve you require.

Sonic welding will not come apart under recommended conditions. The Original MPC Check Valve in ultrasonically welded to hermetically seal the two halves with 97% of the full material strength.

Acutely sensitive to pressure differentials as low as 1/2 PSI. Ideal for all vacuum pneumatic and some fluidic applications.

Fast response between nearly a free flow condition and no flow condition, may be cycled as fast as once per second. Cycle testing of our valve design has proven that under controlled conditions it will withstand 1.8 million cycles. Contact sales with the specifications of your application to find the valve specifically suited for you.

Ultra low leak rates. Less than 2 cubic centimeters per minute. Call or email Sales for information on which check valve is suitable for your application.

Effective in any orientation under recommended conditions. The Original MPC Check Valve can be installed in tubing that is horizontal, vertical, or on an angle. Flow is not affected by gravity.

Five port sizes. (nominal inside diameter of the tube in which it fits) 1/8", 3/16", 1/4", 5/16" and 3/8".

Three housing materials. nylon type 66, polypropylene and PVDF

Four diaphragm materials. fluorosilicone, Viton, silicone and EPDM
