Strainer valve (TH-STV)
The strainer valve (filter valve) is also called filter: its a device that performs filter pretreatment. The filter valve is the filter equipment necessary for the use of hydraulic control valves and sophisticated mechanical products that are prone to clogging. It is an indispensable device of the pipeline series for transporting media. It is usually installed at the inlet end of equipment such as hydraulic control valves, pressure relief valves, pressure relief valves, and fixed water level valves. It is used to eliminate impurities in the media and prevent particulate impurities from entering. The channel creates a wall plug to protect the fittings on the equipment pipeline from wear and blockage. When cleaning is required, just remove the detachable filter cartridge and reload it after processing, so it is extremely convenient to use and maintain.

Strainer features
- The filter valve net adopts a stainless steel double-layer net structure, which is durable and has the characteristics of advanced structure, small flow resistance, and convenient sewage discharge.
- It can be used in various media such as water, steam, oil, nitric acid, urea, oxidizing media and so on.
- According to user needs to set the mesh number of the filter, the general water network is 18-30 mesh, the ventilation network is 40-100 mesh, and the oil network is 100-480 mesh.
- The Y-shaped filter can also be combined with the telescopic joint to form a Y-shaped rod telescopic filter with adjustable installation length.
- Filters can be made according to user requirements.
