Electric control valve is a hydraulically operated valve with solenoid valve as pilot valve. Commonly used in water supply and drainage and industrial systems in the automatic control. According to the electric signal remote control to open and close the pipeline road system, to realize remote operation. Valve closing speed is adjustable, smooth closing without pressure fluctuation. Electric control valve structure is novel, customized on demand, good sealing effect, low resistance, high flow, good sensitivity, long service life and so on. Manual control device is added to this valve, when power failure or circuit failure, this valve can still open or close.

The solenoid valve can be used with AC 220V, or DC 24V, and can be used with normally open or normally closed type according to the occasion. When the valve from the inlet end of the water supply, the water flow through the needle valve into the main valve control room, when the electromagnetic pilot valve is open, the water in the control room through the electromagnetic pilot valve, ball valve out. The ball valve opening degree is greater than the needle valve opening degree, the main valve control room pressure is low, the main valve is in full open state. When the electromagnetic pilot valve is closed, the main valve control room water can not flow out of the control room, the control room pressurization, pushing the diaphragm to close the main valve.

Electric control valve valve body streamlined design, low fluid resistance, large flow, body cover, piston cylinder connection sealed by the gasket and sealing ring, the valve body, piston cylinder, piston double guide, smooth movement, all stainless steel piston cylinder, integral casting piston, NBR sealing ring, removable valve seat, structure, conception, easy maintenance and replacement, piston cylinder with guide holes, appropriate increase in the damping, so that the piston movement is more stable. The piston cylinder with deflector holes, appropriate increase in damping, making the piston movement more stable.
