Imported high pressure self-operated control valve
American YLOK imported self-operated high-pressure regulating valve is an actuator product that does not require any external energy and uses the energy of the adjusted medium to realize automatic adjustment. Different forms of pressure balance structure are used in the valve, no matter whether the pressure range before the valve is large or the flow rate change range after the valve is large, it will not affect the accuracy of the controlled medium pressure value, and the action is sensitive and the sealing is good. It is suitable for explosion-proof, non-energy or automatic control systems that require self-control.
