What is the electric valve driver?
The valves on the chemical process of the device may be at a long distance from the control rooms or high in the air on the towers or raised tanks. The electric valve drive can be used to control them remotely without manual valve rotation. Although all these drives run on electricity, designs may vary significantly and come in different sizes to match different valve applications. Power can be direct current (DC) or alternating current (AC) depending on the plant design. A key factor in all electrical controls is available for torque or power available from the electric motor to open and close the valve.
When the valves are rarely used or handled sticky or abrasive materials, the valve may be difficult to turn at first. Plant designers will specify valve drivers with extra torque to prevent these control problems. Manual control wheels or handles can be added to the action bike to help VolThe valve will try to move the valve. There are different ways to protect the engine, including the torque -limiting sensors, the engine overheating or electric current. These monitor the excessive force of the valve opening, the engine winding temperature or the power flow and switch off the engine to protect it. Regardless of the design, drivers should be purchased with overload protection to prevent valve failure.
On-off-off electric valve The valve is completely open or on, or vice versa when a signal is sent to it. They usually have a limit switch that closes the drive engine when the valve is fully open or closed. The on-off drivers do not provide any flow control and are used primarily on the storage tank or delivery pipe, where simple controls are needed.
Proportional control is another option for the electric valve driver. JackThe approach controller can be connected for opening and closing slowly or faster on the basis of the signal sent from the controller. This allows the valve to control the flow of raw materials into reactors, changing liquid flow or cooling to check the temperature or speed of tank or truck filling to prevent overflow.
The heating and cooling device can use the electric valve drive to control the shock absorber and the valve. The shock absorbers are metal plates suspended inside the valve and furnace pipes. When the furnace turns on and off, the controller can open and close the shock absorber to control the venting gases leaving the furnace. Similar shock absorbers can be installed in the fresh air that enter the furnace to check the air used to combine gas or heating oil, usually associated with sensors that monitor the gases leaving the furnace. Setting the flow air flow and venting current can provide maximum combustion efficiency.
Electrical drivers on the furnace valves MOHou control gas or oil flows into the burner or water flow to the boilery that circulate hot water through the heat building. The heat pumps have a reverse valve that switches the direction of the flow of refrigerant when switching from heat to air conditioning. The electric valve drive can control the valve based on the switch to select heat/cooling in the thermostat inside the building.
