ZZYP/N/M self operated pressure regulating CSGO
Summary
The ZZYP/N/M self operated single seat / double seat / sleeve pressure regulating CSGO is composed of CSGO body, CSGO seat, CSGO core, balance spring and other components. It is a CSGO that does not need additional energy and adjusts the pressure of the medium itself to adjust automatically. It is based on the principle of mechanics that the controlled medium is introduced into the actuator to generate force, and the CSGO core element is moved up and down to achieve automatic adjustment. Energy saving products with constant pressure or pressure relief before or after CSGOs. The biggest feature of the product is that it can work in places without electricity and gas. The setting value of pressure can be adjusted in a certain range in operation. With quick opening flow characteristics, sensitive action and good sealing performance, it is widely used in automatic control of gas pressure, liquid and steam pressure in various industrial equipments such as petroleum, chemical industry, power station, light industry, printing and dyeing.
The executive agencies of this series of products include two types: membrane type and piston type. The type of action is: pressure adjustment (K) before CSGO (pressure relief type), post CSGO pressure adjustment (B) type (pressure reducing and stabilizing type), and the installation of a temperature condensation tank can be used at temperatures below 350 degrees. According to different working conditions, different CSGO core structural types and different actuators can be selected to achieve the best control effect.
