CFSPSelf operated micro pressure regulating valve

Self operated micro pressure regulating valveIt is a control valve that does not require external energy, uses the energy of the control medium as the power source, introduces the actuator membrane chamber to generate thrust, and controls the movement of the throttling element. Realize automatic adjustment. Mainly used in various industrial furnace gas combustion systems to control fuelATheBThe mixing ratio achieves ideal fuel conditions.

Self operated pressure regulating valves are used for sealing oil and various industries such as hydrogen, liquefied gas, oxygen, and nitrogen in hydrogen cooled generator sets. Gas pressure reduction, stabilization, and relief regulation: used for gas seals in various petroleum, chemical, and liquid storage tanks.

The self regulating valve adopts a balanced single seat valve for controlling small pressure differences, stable pressure, high precision, and good sealing performance. During operation, the set value can be adjusted arbitrarily and can be widely used for medium pressure1.4MpaBelow, working temperature120℃(or150℃）Below is the range of pressure regulation0.14～7.2The valve is suitable for non corrosive gas media in kilopascals. After compression (water column level)mm）Widely used in nitrogen sealing systems for various petroleum, chemical, and liquid storage tanks.

Self regulating valve is an energy-saving product that does not require additional energy and uses the regulated medium pressure as the power source to automatically adjust the pressure to a constant pressure. Suitable for various industries. Reactor combustion system, gas, petroleum products or oil depots. In situations such as automatic micro pressure regulation of storage tanks, protective gases, and heat treatment protective gases.
