PK VALVE

CAST STEEL VALVES

  • TILTING DISC CHECK VALVES

    Today, higher velocity and pressure of piping often requires a sophisticated check valve rather than
    conventional swing type valve. PK tilting disc check valve is designed to handle such higher velocities, prevent damages due to turbulence and avoid “water hammer”phenomenon in piping systems, and it is closed quickly
    and quietly. The valve is closed quickly because its pivot(hinge pins) is shut by a very small arc.Moreover, line
    fluid flows both over and under the disc, so that valve closing is cushioned by the line fluid itself. By virtue of
    quick and quiet closing ability, up to now PK tilting disc check valve has earned good reputation as a “nonslam”
    check valve.

  • DUAL PLATE CHECK VALVES

    VALVE FEATURES & ADVANTAGES
    ' - Dual plate Check Valve is economical on installation and maintenance because installation is required less and light weight.
    - Dual plate Check Valve is possible to prevent water hammering due to closing valve disk by operating the spring in
    valve before back flow. Also Due-Check valve prevents large piping the for big gap water levels.
    - Dual plate Check Valve can apply variously in piping line because of less than existing Check Valve on restrictions
    of instaling direction.
    - Life spans is longer than existing Check Valve, and preservation and repair are simple.
    - It's possible to reduce maintenance fee due to longer durability than existing check valve, easy maintenance.E7
