BKVALVE
Butterfly Valves

 With a disc to stop or allow substances from entering, the butterfly valve featured with easy to manipulate is the common pipe component.

 Compatible with different end flange to suit various pipes, concentric or resilient-seated butterfly valves in Bkvalve is ideal for handling granular food, chemicals, and other liquid media. Because of the middle stem manipulating the disc, media flowing through the pipe has zero contact with the body.

 Controlling the flow efficiently and accurately is achievable with Bkvalve’s butterfly valve, as it is produced by molding based on your-required measurement. Targeting specific industries is accessible thanks to the versatile and reliable quality of our zero offset butterfly gate.

Gate Valve

 Companies utilize gate valves as a controllable barrier that can open or close. Most Bkvalve gate valves use a wedge-shaped plate that does not obstruct the flow when the valve is open. The design of the gate valve allows workers to minimize pressure in the valve and allow access to the pipes for regular cleaning.
