  • Plast-O-Matic CK Check Valve

    ,

    Plast-o-matic® type CK valves are self-closing thermoplastic check valves that have a patented diaphragm design which assures dependable, repetitive, bubble-tight sealing and can be mounted in any position. Because they are self-sealing, they’re not dependant on gravity, mounting position or reverse flow, a significant improvement over ball check valves. No internal sliding or loose parts to slam or vibrate eliminates chattering and ensures silent operation.

  • Plast-O-Matic CKD Check Valve

    ,

    Plast-o-matic® type CKD valves are compact diaphragm check valves that are designed to prevent reverse flow or extremely corrosive and ultra pure liquids. They utilize a flexible elastomer disc for their sealing action. This sensitive disc offers very low pressure sealing, is self-centering, and requires extremely minimal pressure to move to the open position.

  • Plast-O-Matic CKM Check Valve

    ,

    Plast-o-matic® type CKM valves are self-closing thermoplastic check valves that have a patented diaphragm design which assures dependable, repetitive, bubble-tight sealing and can be mounted in any position. Because they are self-sealing, they're not dependant on gravity, mounting position or reverse flow, a significant improvement over ball check valves. No internal sliding or loose parts to slam or vibrate eliminates chattering and ensures silent operation.

  • Plast-O-Matic CKS Check Valve

    ,

    Plast-o-matic® type CKS valves are self-closing check valves that feature a normally closed design which is self-sealing, not dependent on gravity, mounting position or reverse flow, and a significant improvement over ball check valves. Leak-free sealing protects against the potential hazards created by reverse flow of corrosive liquids such as acids, caustics, and chlorine solutions.

  • Plast-O-Matic MPC Check Valve

    ,

    Plast-o-matic® type MPC valves are miniature plastic check valves that are designed for exceptionally high quantities of tubing check valves at an exceptionally low cost. They feature superior sensitivity, very rapid response, low cost, and application flexibility. They also utilize a flexible elastomer diaphragm and can be installed in any position.
