Product profile
The 400X flow control valve consists of a main valve, a flow regulating valve, a needle valve, a pilot valve, a ball valve, amicro-filter and a pressure gauge. By adjusting the opening of the main valve, the fiow through the main valve remainsunchanged. Flow control valve uses hydraulic self-control, does not need other devices and energy, easy maintenance, flowconitrol is siable. Fiow conirol valve producis are widely used in high-ise buildinas, living areas and other water supply networksystems and urban water supply projects.
Working principle
When the valve is fed water from the inlet end, the water into the main valve control room through the needle valve, and flowsout of the main valve control room through the pilot valve. At this time, the main valve is in a fuly open state. The main valve canbe set at a certain opening by setting the fow control valve above the main valve. Adiusting the opening of the needle valve ancadiusting the spring pressure of the pilot valve can keep the opening of the main valve at the set value. When the pressurechanges, the pilot valve can be automatically adjusted to keep the flow constant.
