Product Advantage

Simple structure, good interchangeability and low price.

The valve stem seal is not easy to deform, avoids normal valve stem leakage, and the overall support is good, stable and firm.

The less seat rubber, the less likely it is to swell, making it easier to keep torque within the proper range.

The two-piece valve stem with pinless connection has a simple and compact structure, and is very convenient for maintenance and disassembly.

The butterfly plate has the function of automatic centering, and the butterfly plate and the valve seat are closely matched

The phenolic back seat is non-shedding, stretch-resistant, leak-proof and easy to replace.

The gear operated U-shaped butterfly valve is mounted between two flanges. Butterfly valves are held in place by bolts or studs and nuts between the flanges. Of course, it is not possible to disconnect only one side of the piping system from the valve with this type of installation.
A butterfly valve is a valve that isolates or regulates the flow of a fluid. The closing mechanism is a disk that rotates.

All surfaces of the valve interior is clean, dry and free from grease before painting. The valve surfaces coated with epoxy coating approved for drinking water applications.
