STF filling valve, Taifeng filling valve

Where are the cheaper filling valves produced? I heard that Shandong Taifeng Hydraulic is an old factory that specializes in producing filling valves for more than 20 years. It is of high quality and low price. Welcome to buy it
The series of filling valves belong to the stop valve type and are mainly used for large-flow filling of various types of cylinder plug cavities. Or drain the fluid to increase its idle speed and return speed. It can be installed in the pipeline through high-pressure flange stacking, so installation and maintenance are very convenient and can replace imported products. This series of liquid-filled valves are normally closed, and their working principle is similar to that of a hydraulically controlled one-way valve. The flow direction r can flow freely, while the flow direction r is controllable. When there is control pressure at the port, the one-way valve opens r. When the port pressure is relieved, the one-way valve closes r differently.
Characteristics of liquid filling valve
. Low opening pressure and good self-priming performance
. Smooth flow channel design and small flow resistance
. Low control pressure and reliable reset
. Intermediate flange The installation and connection form is convenient for maintenance
. Compact structure and small overall size
