Self-operated Pressure Reducing Valve
Introduction:
The self-operated pressure reducing valve adjusts the flow of the medium by controlling the opening of the opening and closing parts in the valve body, and reduces the pressure of the medium. Within a certain range, when the inlet pressure is constantly changing, keep the outlet pressure within the set range to protect subsequent living and production appliances.
Application:
Self-operated pressure reducing valve is composed of valve body, valve seat, valve core parts, etc. It is an energy-saving product that can automatically adjust the pressure by relying on the pressure change of the regulated medium itself without external energy. It can be used for non-corrosive liquids.
Pressure control devices for media such as , gas and steam. Self-operated pressure reducing valves are widely used in petroleum, chemical, metallurgy, light industry and other industrial sectors, as well as in urban heating and heating systems for deceleration and pressure reduction and stabilization of gas, liquid and steam media in various equipment (used for post-valve pressure reduction) ) Automatic control of pressure relief and pressure stabilization (for pre-valve pressure control). The pressure reducing valve can choose different spool structure types and different actuators according to the different working conditions of the user to achieve the ideal control effect.
Features:
1. The pressure reducing valve does not need an energy-saving automatic control system with external driving energy, and the equipment cost is low, which is suitable for hazardous environments.
2. The structure of the pressure reducing valve is simple, and the maintenance workload is small.
3. The set point is adjustable and has a wide range, which is convenient for users to adjust continuously within the set range.
4. Compared with the cylinder type mechanism, the diaphragm type actuator has higher detection accuracy and more sensitive action.
5. The pressure balance mechanism is adopted in the valve, so that the regulating valve has sensitive response, accurate control and large allowable pressure difference.
