ANSI 150# through 2500# full port and reduced port available in any alloy, forged body valve sizes: 1/4” through 12” socket weld, butt weld, NPT, R.F. Flanged, R.T.J. Flanged


    Sealing Capabilities
  • The seat is at an angle which prevents media from building up. As back flow occurs, the seat is flushed clean prior to contact with the piston. Class VI leakage available with TFE Seats.

    • Full Area Flow
  • The Port opening on the valve is a full port. This is unlike other piston check valve designs which have a reduced port opening. Thus, more flow is available with the Jarecki Piston Check Valve. Please note, however, some of our designs are standard port. Please specify upon your inquiry if you have a preference.

    • Compact Design
  • The relatively small size of the valve makes it easy to install and handle. The light weight construction also makes it cost competitive

    • Spring Loaded
  • The piston is spring loaded so that the valve can be mounted vertically or horizontally. The springs are contained with minimal area exposed to the media. Guides properly locate the piston during the closed and open position. This prevents the piston from binding up inside the valve and insures a good reliable shut-off.
  • High pressure
  • High temperature
  • Chlorine
  • TiCl4
  • Steam
