A Fluorine lined wafer butterfly valve is a compact valve designed to clamp between two flanges in a pipeline, featuring four alignment holes. It provides a strong seal with a rubber or EPDM seat. Unlike lug-style valves, it cannot serve as an end-of-line valve and requires full line shutdown for maintenance.

The design and manufacture comply with the basic structure of Chinese national standards (the butterfly shaft coincides with the center of the valve body/seat)
A.D71F4 fully lined valve body, the whole village/butterfly plate, the whole village layer/lining layer, the butterfly plate and the butterfly plate shaft double D cooperate with
B.D71F46 fully lined valve body, full lining/plate, full lining/lining and butterfly plate into one
C.D71F4(46)/P semi-lined valve body is all solid/the butterfly plate is stainless steel/the butterfly plate is matched with the doubled of the butterfly plate shaft.
Their slim design saves space and makes them easy to install in systems with tight space constraints.
Wafer butterfly valves are economical due to their simple design and lower material requirements compared to other valve types.
They fit easily between flanges, without requiring additional bolts or fasteners, simplifying the installation process.
With fewer moving parts, they are easy to maintain and have a longer service life, reducing operational costs.
Wafer butterfly valves offer effective sealing, preventing backflow and ensuring system integrity across various applications.

Y type Strainer is an indispensable filter device in the pipeline system of conveying media made by stainless steel. It is usually installed at the inlet end of pressure reducing valve, pressure relief valve, fixed level valve or other equipment to remove impurities in the media to protect the normal use of valves and equipment. The characteristics include advanced structure, low resistance, convenient blowdown and so on. Applicable media can be water, oil, gas. Generally, the water network is 18 to 30 mesh, the ventilation network is 10 to 100 mesh, and the oil network is 100 to 480 mesh.
