A gapless gate valve (also known as knife gate valve) made of wear-resistant rubber developed by international advanced technology. 【Processing capacity】: 1.6MPa/cm² 【Scope of application】: Xinhai Knife Gate Valves are in the form of large opening and large closing, and are mainly used for abrasive and corrosive slurry media under the conditions of full opening and full closing, such as cyclone feeding, double-circuit pipeline, etc.
Xinhai Knife Gate Valve has a long service life, and its lining is made of wear-resistant rubber developed with unique nano-formulation technology.
The sealing performance is strong, and the wear-resistant rubber elasticity of the inner lining is higher than 80%, which ensures that the seal does not leak and is not easy to cause water hammer impact;
The flow port is not easy to be blocked, due to the wear-resistant rubber valve lining, the surface is smooth and neat, and the blocking situation is almost zero;
Simple structure, easy operation and maintenance;
No pressure loss.
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.
