The features of solenoid valve are fast open and fast close, low cost, compact design, easy to install. Meanwhile, it suitable for small machine. But it has a limited size range for choice. The motorized valve could be motorized ball valve, motorized butterfly valve, motorized gate valve and motorized globe valve to achieve start, stop, regulate and separate the flow rate. Motorized valve has signal feedback and it means it could be controlled remotely and let your project more automated.
Compare with a solenoid valve, a motorized valve could achieve more function but higher cost. Meanwhile, as an actuator and valve manufacturer, COVNA will provide the quality motorized valve and solenoid valve for your project. Helping you save time and cost.
Sep 10, Product Item. Motorized ball valve. Actuator Options. Connection Options. Flanged, threaded, welded, tri-clamp, double union or wafer. The trim of air directional control valve moves along axial direction of seat to control intake and exhaust. After working air pressure is input to valve port, trim is pressed against seat under the action of spring and gas pressure, compressed air cannot flow out from valve port; The trim moves downward and leaves the seat after the stem is subjected to a downward force, compressed air can be output from one port to the other.
In another case, the trim leaves the seat under the action of spring force, compressed air flows from one port to the other. The trim is pressed against the seat to close valve port under upward force of the stem, the flow path is closed, no compressed air flows out from valve port. Solenoid valve is suitable for some special process requirements, such as leakage, special fluid media, etc.
Air directional control valve is an accessory of the heating and heating system, and is generally used in electric water heaters, solar water heaters and centralized hot water supply systems. It has good effect on gas medium and small diameter liquid, low cost and convenient maintenance. Air directional control valve has a larger working force than solenoid valve, and maximum working pressure is larger than that of solenoid valve.
In combination with a positioner In combination with a positioner, the solenoid valve provides additional emergency shutdown to extend the control function of the valve assembly.

Hooked up as required. Safety function SIL. Type of protection. However, the motorized valve needs to add a reset device. The action principle of solenoid valve is the straight stroke, for the diaphragm or pilot. The action principle of motorized valve is the angle stroke. It has double-sided sealing and not easy to leak.
The action principle of solenoid valve is the straight stroke, it sealing by the spool itself gravity and the force of the electromagnet to achieve. So the solenoid valve can only be installed horizontally, other installation may cause it leakage. Motorized valve actuator switch action in place, then by the internal micro-switch power. Longer service life than solenoid valve, and stable performance.
The structure of solenoid valve is simple, low protection level, easy to be affected by external dust and air, temperature. Basically, protects the actuator from dust and moisture.
