The ZSHWB Series is a high-performance double eccentric butterfly valve designed for both regulation and shut-off functions. It features an advanced eccentric structure in both the valve disc and sealing ring, ensuring excellent sealing performance, easy maintenance, and a long service life. This makes it ideal for use in various industries such as metallurgy, oil, chemical engineering, power generation, and natural gas processing.
Butterfly valves are a type of quarter-turn valve that uses a disk to control the flow. The disk is mounted in the center of the pipe and connected to an actuator outside the valve. Rotating the actuator turns the disk either parallel or perpendicular to the flow, allowing for quick shut-off. Unlike ball valves, the disk is always present in the flow, which may cause a pressure drop regardless of the valve position.

Stainless steel internal accessories
ensure minimal maintenance.
No special tools are needed for
maintenance, so the operation is very simple and convenient.
Unconditionally providing super
quality stainless steel floating ball.
The design of filter screen structure
can effectively prevent the impurities in the system from entering the air
release valve to ensure that the valve's automatic exhaust function is normal.
When the system equipment discharges
water, the air release valve can suck in a certain amount of air to eliminate
the negative pressure in the system and improve the fluidity of discharging
water.
