high pressure cut-off valve opening and closing of the component is attached to a flat or tapered plug surface of the disc, the disc along the linear moving fluid.

stem movement is for bar type ( Stem type, hand wheel does not move up and down) And lifting lever ( The handwheel with the valve stem rotation) , the body installed on the nut. High pressure cut-off valve is only applicable to full open and close, are not allowed to adjust and throttling. The structure of the high pressure cut-off valve advantages: 1. The design and manufacture of high voltage power station valve with ANSIB 16. 34 and E 101 standards, can be used directly and export equipment form a complete set. 2. Inside the valve cavity using the tight sealing structure. Inside the cavity pressure, the greater the sealing performance, the better. Branch pipe welding on both ends to meet different acceptance requirements. 3. Body and cover with sufficient strength and rigidity. The channel is smooth, fluid resistance is small. 4. Disc and seat sealing surface adopt Stalli cobalt-based hard alloy. Sealing surface with high hardness, wear resistance, high temperature resistant, corrosion resistance, scratch resistance, etc. It's a long service life. 5. The stem by proton nitriding and surface nitriding treatment, has good corrosion resistance and scratch resistance. 6. Hood filling and packing depth is reasonable, packing with corrosion inhibitor, reliable sealing, auxiliary switch assembly stability. 7. Valve has a sealing structure, to ensure that the valve when the valve opens not leak to the outside of the valve stem. Check valve can be divided to rotate the check, according to different structural type, high pressure booster door vertical check valve, check valve, etc. Described in the rotating disc check valve with disc shape, and revolve around described the seat of rotation of the channel. Because the valve passage streamlined, movable resistance is less than the activities of the lift check valve resistance, suitable for low flow, low activity of the valve. Replacement of large diameter often places, but not suitable for pulsating flow, sealing function than to ascend.
