The pressure regulator can basically be said to be a pressure reducing valve, the working principle of the pressure reducing valve is as follows: the high-pressure medium is charged into a relatively large cavity through a small hole to achieve pressure reduction, in fact, by interception of the pressure reduction, the two sides of the diaphragm or piston are out of the mouth, one side is the pressure given artificially, and the control of the small hole size of the valve stem and diaphragm (piston) connected, so that as long as a fixed pressure is given, then the pressure out of the mouth will always be equal to this pressure, this artificial given pressure can be provided by the spring or air source or hydraulic source.
In addition, we have other accessories such as Circular machine oiler, Control Panel, Adjustable Yarn Bobbin Cover, Synchronous Belt, Needle Cylinder and so on.
According to the use and function, main parameters, pressure, medium operating temperature, special purpose (that is, special, special valve), drive energy, structure, etc. are classified, among which the most commonly used classification method is to divide the control valve into nine categories according to the structure, 6 for straight stroke, 3 for angular stroke.
Pressure reducing valves are divided into compact pressure reducing valves, medium flow pressure reducing valves, conventional high pressure reducing valves, secondary pressure reducing valves, and low pressure large flow pressure reducing valves according to the characteristics of use.
Compact pressure reducing valve: PR series compact pressure reducing valve, single-stage diaphragm pressure reducing structure, stainless steel diaphragm pressure transmission, stable output, suitable for pure gas, corrosive gas and non-corrosive gas; Features, corrugated diaphragm ensures precise pressure regulation; metal-to-metal diaphragm sealing; Spring loading to adjust the pressure; Built-in filter; Panel mounting is optional.
Medium flow pressure reducing valve: PM series medium flow pressure reducing valve, single-stage diaphragm pressure reducing structure, stainless steel diaphragm pressure transmission, stable output, mainly used in medium flow gas system;
