U Type Butterfly Valve is a type of butterfly valve that is designed to regulate the flow of fluids or gases in various applications. This valve is named after its U-shaped body, which is similar to the letter U. It is usually used in pipelines that require quick and frequent operation, and where space is limited...
The U-shaped butterfly valve is manufactured by Chinese supplier Shanxi Guzhu Industrial Co., Ltd. Its features include small size, light weight, and easy installation and maintenance. Its structure is simple and compact, it can open and close quickly at 90 degrees, has small operating torque and has significant energy saving effect. The flow curve tends to be straight, the regulation performance is excellent, and it has the durability of tens of thousands of switching operations. Suitable for various media and wide selection of materials. Comply with EN593, ISO 5752, BS5155 and AWWA C504 standards, working pressure is 10bar, 16bar or 25bar, made of ductile iron.

Verify that the valve size, pressure rating, and material compatibility match the system requirements.
Inspect the valve and ensure that the sealing surfaces are clean and free from defects.
Install the valve between properly aligned flanges, with the disc in a slightly open position to avoid damage to the sealing surfaces.
Apply gasket material, if required, between the valve and flanges, ensuring a tight seal.
Secure the flanges using the appropriate bolt and nut combination, tightening bolts in a star pattern for even pressure distribution.
