  • 01

    The flow port is not easy to be blocked. Due to the wear-resistant rubber valve lining, the surface is smooth and tidy, and the blockage is almost zero; 

  • 02

    Wear-resistant index id over 128% and its service life is 2-4 times longer than ordinary valves under the same working conditions;

  • 03

    Xinhai wear-resistant rubber as liners of knife gate valve owns high resilience up to 80% and high sealing performance, no leakage;

  • 04

    Simple structure, convenient operation and maintenance;

  • 05

    No pressure lose.

Product Structure

Xinhai knife gate valve is mainly a manual gate valve. Xinhai Mining can also manufacture the electric and pneumatic gate valve according to the needing of customers. Three kinds of gate valve can be carried out by the remote control. In addition, the valve body is fitted with oil nipple to reduce the friction on gate and force moment of opening and closing of the valve. Spool made of the wear–resistant rubber, has the small specific gravity, is easier to replace.
