Self-operated Micro-pressure Regulating Valve
Introduction:
The self-operated micro-pressure regulating valve belongs to the series of self-operated pressure regulating valves, and is a self-operated valve that does not require any external energy. Valves controlled by the medium’s own energy.
Application:
The self-operated micro-pressure regulating valve adopts a balanced single-seat valve, and the set value can be adjusted arbitrarily during operation. Therefore, it is suitable for micro-pressure automatic adjustment of various industrial furnace combustion system fuel gas, petroleum products in process or oil depot storage tank protection gas and heat treatment protection gas.
Features:
1. The adjustment spring is designed above the membrane actuator, which is convenient for on-site debugging.
2. There is no packing, there is no friction in the up and down movement of the valve stem, and the upper seal is absolutely reliable.
3. The sensitive components of the actuator are extremely sensitive, and a very small pressure change will be sensed.
4. The valve body is in the form of four-way.
5. Balanced structure, not affected by the pressure in front of the valve.
