Two Pieces Check Valve

Two Pieces Check Valve

The check valve assembly comprises a retainer and a valve including a dome-shaped element, and is adapted for use in a tubular member wherein the retainer grips the inner face of the tubular wall to position the valve assembly and the dome-shaped element fits against the inner wall of the tubular member. Pressure within the dome element causes it to expand and snugly engage the inner wall of the tubular member to cut off flow.

A two pieces check valve device comprising a rubber sealing element and a plastic carrier member, the assembly having primary usage in hydraulic and pneumatic systems. A through bore in the plastic carrier member receives the sealing element, which is formed with an annular groove in which the carrier member is removably secured. The through bore and annular groove may be correspondingly tapered to facilitate assembly and disassembly of the check valve device.

Although there are many check valves on the market today which operate in the low pressure area and also have reasonable rang, most of such units have unacceptable accuracy varations. But the two pieces check valve has very accurate and consistent flow characteristics over a wide rang of pressure from very low to moderately high.
