Product overview

      The electric high temperature and high pressure gate valve is suitable for the pipeline of various systems of petroleum, chemical, hydraulic and thermal power stations with nominal pressure PN16.0-32.0MPa and working temperature ≤540℃(of which P57170V is 570℃) to cut off or connect the pipeline medium.

Product characteristics

1, the valve cavity adopts pressure self-tightening sealing structure, good sealing performance.

2, the sealing surface of the valve disc and seat is made of cobalt-based cemented carbide surfacing, wear resistance, high temperature resistance, good abrasion resistance and long service life.

3, the valve stem by anti-corrosive nitriding treatment, has good corrosion resistance and abrasion resistance.

4, high temperature creep resistance design.

5, the valve cover stuffing box depth is reasonable, filling with corrosion inhibitor, reliable sealing.

6, the valve has an upper sealing structure to ensure that the valve stem will not leak when the valve is opened.

7, the structure of the opening and closing parts can be designed into single board, double board, parallel double board and other different forms according to user requirements
