W Series Valve
Product Overview
Patented Technology
The one-piece casting valve body and damage-free sealing system can achieve reliable sealing, avoid scratches and wearing. The self- cleaning design effectively cleans interior of the valve body to prevent blocking. The performance is safe and stable, and the switch is smooth.

When the gate valve is closed, the sealing surface can only rely on the medium pressure for sealing, that is, only rely on the medium pressure to compress the sealing surface of the gate to the other side of the valve seat to ensure the sealing surface seal, which is self-sealing. Most of the gate valves are forced to seal, that is, when the valve is closed, relying on external force to compress the gate to the valve seat for ensuring the sealing performance of sealing surface. The valve body is precision casted, and the precise geometrical dimensions make the interior of the valve body do not need any finishing to ensure the sealing of the valve.


• Many actuating structure can be selected such as manually operated and pneumatically operated; different actuating structure can be conveniently adjusted according to the working conditions; 

• One-piece casting valve body ensures strength and sealing, with stable performance and long service life; 

• A variety of connection flange standards are available and can be installed on various pipes; 

• No gate plate or gate rod packing is required, thus prevent packing leakage pollution; 


It is commonly used in coal, power, environmental protection and other industries for controlling the transportation of solid and liquid mixed two-phase flow medium.
