On-off electric valves are also called two-position electric valves, which have outstanding advantages and are widely used in industrial production processes. For example, in industries such as power plants and petrochemical industries, the worksites in these industries have high risk factors and high labor intensity, which is very unsafe for frontline operators.
1. High temperature resistance and chemical corrosion resistance;
2. The electric valve has a simple structure and a long service life;
3. Wide application range, suitable for almost medium, high viscosity;
4. Its explosion-proof cost is low.
Motorized valve are usually composed of electric actuators and valves. The electric valve uses electric energy as power to drive the valve through an electric actuator to realize the opening and closing action of the valve. So as to achieve the purpose of switching the pipeline medium.
Regulating electric valve action is an analog quantity, which is a continuous position signal. Therefore, the remote control of the electric valve requires the output of the analog quantity of the distributed control system, so that the valve can be opened or closed to any position. Since remote control cannot see the working status of the on-site valve, feedback information needs to be introduced into the distributed control system. At this time, the analog signal is introduced into the distributed control system.
The workmanship is in place, and the quality is very good at a glance!
Regular customers, the cooperation has been very happy!
The workmanship is fine, the size is right, the design is in place, and the service is attentive and attentive!
Motorized valve is a power supply to drive the motor rotation, thus opening or closing the valve of a device, and withstand voltage shocks. The rotating range of the electric valve is adjustable. The rotating range can be adjusted by inputting the specified current and voltage signals.
Motorized valve mechanisms are prevented from advancing too far by using a set of electrical limits which cut the motor supply when a valve is either fully opened or closed. When the valve needs to be adjusted again, the motor's direction is simply reversed to turn the valve in the opposite direction.
COVNA is a motorized valve manufacturer over 22 years in China. We offer motorized ball valve, motorized butterfly valve and motorized gate valve and motorized globe valve for your project. If you have any need about motorized valve, please feel free to contact us.
This little known plugin reveals the answer. Rotary or quarter turn motorized valves are the valve type with the quickest actuation times and typically use a cam or central spindle advance mechanism. These valves are among the most common motorized valve types and include ball and butterfly valve varieties.
