Product Overview: The self operated pressure regulating valve does not require external energy, and uses the energy of the regulated medium as the power source to introduce an actuator to control the position of the valve core, change the pressure difference and flow rate at both ends, and stabilize the pressure before (or after) the valve. It has the advantages of sensitive action, good sealing performance, and small pressure set point fluctuations, and is widely used for automatic control of pressure reduction and stabilization of gas, liquid, and steam media. There are two types of actuators: membrane type and piston type; There are two types of functions: post valve pressure regulation for pressure relief (B-type) and pre valve pressure regulation for pressure relief (K-type). The nominal pressure ratings of products include PN16, 40, and 64; Valve body diameter range DN20~300; There are three levels of leakage: Level II, Level IV, and Level VI; The flow characteristic is fast opening; The pressure is adjusted in stages from 15 to 2500kPa. It can be combined as needed to meet the user's working conditions.

200X pressure reducing valve is a kind of valve used for parallel connection of fire water and domestic water in the water supply system, used to allocate the direction of water supply.
Check valve can regulate the opening and closing speed. When the pump starts or stops running, it can be adjusted to the best opening or closing speed with the on-site adjustment.It is suitable for mining enterprises and high-rise buildings to reduce water hammer and water hammer in direct water supply and drainage system by water pump, so as to achieve the effect of safe closing.
The 500X relief/hold valve is mainly used in fire fighting or other water supply systems to prevent system overpressure or to maintain pressure in fire fighting water supply systems.
400X flow control valve is a kind of valve used to allocate the direction of water supply in parallel water supply system for fire protection and domestic use.
The 600X electric control valve is a hydraulic operated valve with solenoid valve as the guide valve.
700X water pump control valve is a kind of reverse valve installed at the outlet of water pump in high-rise buildings and other water supply systems to prevent the backflow of media.
Flange pressure reducing valve from the general thread of the pressure reducing valve, its connection flange, this is a control valve in the body of the opening of the opening and closing of regulating the flow of medium, the medium pressure is reduced, at the same time with the aid of the role of the valve after pressure adjust the opening of open-close part, keep the valve after pressure within a certain range, under the condition of the inlet pressure changing, keep the outlet pressure within the scope of the set, protection appliances for production from then on.
Model 200P pressure reducing valve is a direct acting type adjustable pressure reducing valve, using diaphragm type hydraulic operation, can be installed horizontally or vertically in water supply, fire fighting system or other clean water system.
