Applications of the Motorised Valve and Solenoid Valve

Applications of the Motorised Valve and Solenoid Valve

There are great differences between motorised valves and solenoid valves!


Solenoid valve is a type of motorised valve; it uses the magnetic field generated by the electromagnetic coil to pull the valve core, thereby changing the on-off of the valve body, the coil is de-energized, and the valve core is retracted by the pressure of the spring.


1. What is an motorised valve?


1) The motorised valve simply uses the electric actuator to control the valve, so as to realize the opening and closing of the valve. It can be divided into upper and lower parts, the upper part is the electric actuator valve, and the lower part is the valve.


2) There are two types of motorised valves, one is the angular stroke motorised valve: the angular stroke electric actuator is used in conjunction with the angular stroke valve to realize the internal rotation of the valve within 90 degrees to control the on-off of the pipeline fluid;


3) The other is a straight-stroke motorised valve: a straight-stroke electric actuator is used in conjunction with a straight-stroke valve to realize the up and down action of the valve plate to control the on-off of the pipeline fluid. It is usually used in conjunction with equipment with a higher degree of automation.


4) The motorised valve is usually connected by an electric actuator valve and a valve, and becomes a motorised valve after installation and debugging. The motorised valve uses electric energy as power to connect the electric actuator to drive the valve to realize the opening and closing and adjustment of the valve. So as to achieve the purpose of switching or adjusting the pipeline medium.


2. The difference between the application scope of the motorised valve and solenoid valve


1) The solenoid valve has excellent anti-leakage performance, it opens and closes quickly, and has low power. It is suitable for use as a cut-off in some chemical pipelines such as corrosion and toxicity.


2) Motorised valves are mostly used for the regulation of pipeline flow. They are normally installed at the outlet of air supply and refrigeration pipelines. They can also be used in liquid pipelines. They are widely used in canned pipelines and sewage treatment pipelines for beverage production.


3. Applications of motorised valves and solenoid valves


1) Solenoid valve: It is used for switch control of liquid and gas pipelines, and it is a two-position DO control. Generally used for the control of small pipelines.


2) Motorised valve: It is used for analog adjustment of medium flow in liquid, gas and wind system pipelines, and is controlled by AI. In the control of large valves and wind systems, electric valves can also be used for two-position switch control.


3) Solenoid valve: It can only be used as switch value, it is DO control, and it can only be used for small pipeline control. It is common in pipelines of DN50 and below, and there are very few upwards.


4) Motorised valve: can have AI feedback signal, can be controlled by DO or AO, more common in large pipelines and air valves, etc.
