    Bolted bonnet, swing and lift the valve sealing surface of metal.

     Body and bonnet connection form

     Class150~Class900 using bolted bonnet; by Class1500~Class2500

     Class150~Class300 check valve with stainless steel graphite spiral wound gasket; Class600 check valve can be made of stainless steelgraphite spiral wound gasket can also be used metal ring gasket;Class900 check valve can be made of metal ring gasket,Class1500~Class2500 valve with self sealing ring.

Chains Belts Guide

    Valve seat

      Carbon steel valve seat usually uses forged steel material, the sealing surface of the valve seat can according to the customer request spray welding hard alloy, NPS ≤ 10''check valve adopts a separate type is threaded into the valve seat, if the user needs towelding valve seat structure can also be provided; NPS ≥ 12 valveseat structure by welding; stainless steel check valve valve seatwith integral or in body welding hard alloy directly after processingthe seat. If the user needs, the stainless steel valve seat can also be used separate threaded and welded in seat structure.

     Structure characteristics of cast steel swing check valve

    Large diameter of the valve design with a ring, convenient lifting.

    Bolted bonnet, flange gasket type can be selected according todifferent levels of pressure;

    CLASS600 check valve can be used self tight seal pressure.

    Valve limiter, prevent the valve open position is too high and can not be closed.

     Solid pin installation precision, high strength, ensure the service performance and the service life of the valve

     Rocker has enough strength, close enough degrees of freedom tothe valve closed.

     The valve has enough strength and rigidity, the sealing surface of the valve clack can according to user requirements of surfacingmetal materials or embedded nonmetal materials.
