Product description

The electric high temperature and high pressure gate valve is suitable for the pipelines of various systems of petroleum, chemical, hydraulic, and thermal power plants with a nominal pressure of PN16.0-32.0MPa and a working temperature of ≤540℃ (where P57170V is 570℃). Road medium.

Features

1. The middle cavity of the valve adopts a pressure self-tightening sealing structure with good sealing performance.

2. The sealing surface of the valve disc and the valve seat is made of cobalt-based hard alloy surfacing welding, which is wear-resistant, high-temperature resistant, good scratch resistance and long service life.

3. The valve stem is treated with anti-corrosive nitriding, which has good anti-corrosion and scratch resistance.

 4. High temperature creep resistance design.

5. The depth of the bonnet stuffing box is reasonable, the packing is added with corrosion inhibitor, and the sealing is reliable.

6. The valve has an upper sealing structure to ensure that there will be no leakage at the valve stem when the valve is opened and running.

7. The structure of the opening and closing parts can be designed into different forms such as single plate, double plate, parallel double plate, etc. according to user requirements
