Self tight seal double gate valve

The connection gate valve is suitable for cutting or connecting channel medium on the pipelines of various systems in oil, chemical, hydraulic and thermal power stations with nominal pressure PN20.0~32.0MPa and operating temperature less than 540oC (which P57170V working temperature is 570 C).

Structural characteristics
1, design and manufacture according to JB/3595, E101 and other standards.
2, the use of the flow path equal diameter structure, greatly reduces the flow resistance coefficient and energy loss, significantly improve the valve life and performance.
3, the valve middle chamber adopts the pressure self tightening type sealing structure, and the sealing performance is good.
4. The sealing surface of the gate and the valve seat is made of hard alloy surfacing. It has good wear resistance, high temperature resistance, corrosion resistance and abrasion resistance.
5. The surface of the stem is corrosion-resistant and nitriding. It has good corrosion resistance and scratch resistance.
6, the structure of the opening and closing parts can be designed as single board, double board and parallel double board according to user's requirements.
7, equipped with multi turn electric device, remote control and local operation can be realized.
8, Z62Y series for double gate valve design, automatic correction process error, always keep the sealing surface 100% degree of fit, especially for users on-site maintenance.
