Combination Valve Of Butterfly Valve/Check Valve/Strainer Is Online

The combination valve produced by HEBEI BESTOP INDUSTRY SUPPLY CO., LTD which integrates butterfly valve, strainer and check valve, It has the functions of cutting, filtering, check and remote intelligent control. It effectively solves the different needs of customers in different process pipelines and saves cost and space.

Cutting part : the opening and closing of the medium is controlled by the butterfly valve, the operation is simple and the torque is small.
Filtration part : multi-row U-shaped filter effectively filters the impurities in the medium and removes the dirt in the fluid medium. The butterfly valve opens, the filtration system enters the running state, and the butterfly valve closes the filter chamber automatically before and after closing. It can open the valve cover of the filter chamber and the screw plug or valve at the bottom of the valve, remove the filter screen for cleaning, and clean the dirt in the filter chamber.
The check part : open by the pressure of the medium downstream to overcome the torsion of the spring, and seal by the torque generated by the spring and the sealing specific pressure generated by the pressure of the medium upstream to prevent the medium backflow, thus effectively preventing the occurrence of water hammer phenomenon.
Remote intelligent control part : when needed in the field operation system, the medium pressure, temperature and other data in the system can be carried out according to the working condition system. The driving device is electric, which can remotely operate the opening and closing and adjust the opening Angle, and can also be timed switch.

The perfect combination structure of the multi-functional combined valve(butterfly valve+check/butterfly valve+strainer)is compact. It has both the excellent function of filtration and the function of cutting off before and after itself. It is convenient to install, saves the installation space and raw materials, and reduces the use cost of customers. It can also be different materials according to the working medium and other factors, select different driving modes such as manual / pneumatic / electric, and install on vertical / horizontal pipelines.Widely used in water supply and drainage, building control, central air conditioning, seawater desalination, heating and other pipeline system fluid cut-off, open, media filtration, backflow prevention, as well as remote monitoring media pressure, temperature, etc.
