[0002] The pressure reducing and sustaining valve has the functions of both reducing pressure and sustaining pressure. It can maintain the pressure stability by adjusting the flow rate while reducing the pressure of the fluid or gas. This valve device is very useful in some occasions where precise pressure control is required. For example, in the petroleum and chemical industries, high-pressure fluids and gases need to be reduced in pressure and sustained in order to ensure the safe and stable operation of the system.

[0003] At present, in the actual application of pressure reducing and sustaining valves, traditional pressure reducing and sustaining valves mostly install supporting accessories such as solenoid heads and pilot valves on the outside of the valve body through iron sheets, and they need to be connected by pipe fittings. Therefore, it is more troublesome to carry out maintenance in the later stage, and after long-term use, the connection strength of the iron sheet decreases, which may cause accessories to fall off.
