Introduce:
Ball valve , opening and closing parts (ball) driven by the valve stem, and around the axis of the ball valve for rotating movement of the valve. It can also be used for fluid regulation and control, the hard seal V-type ball valve with V-type core and surfacing carbide metal valve seat has a strong shear force, especially suitable for containing fiber, small solid materials and other media. The multi-pass ball valve in the pipeline can not only flexibly control the medium confluence, shunt, and flow switch, but also can close any channel and make the other two channels connected. This type of valve shall generally be installed horizontally in the pipeline. Ball valve according to the driving mode is divided into: pneumatic ball valve, electric ball valve, manual ball valve.

The fluorine-lined butterfly valve is engineered for aggressive chemical and ultra-pure applications. Its fluorine lining resists chemical attack from various compounds, while a flexible 360-degree backup liner ensures bubble-tight shut-off. This maintenance-free valve features redundant shaft seals, a 90-degree clockwise operation, and zero leakage. Main parts and materials Name/Material WCB CF8 CF3 CF8M CF3M Body […]
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.
