How To Choose A Motorized Valve

When the valve is closed, you must be sure that it is in the range of pressure.

 

Valves are generally used to handle hot fluid or cold fluid.It is very important to determine how low or high temperature is the medium of the valve. There are different materials, such as ceramic, stainless steel, and PVC are used in the manufacture of valves.Each of them is applied to a certain temperature range.

 

Specific applications and fluid control systems are designed to handle different types of fluids.Some valves are used to deal with dams and reservoirs of hydroelectric power plants.There is also used for the normal flow of chemicals.There are a number of special design, used for radioactive material, to ensure that the valve will not leak radiation.

 

It is also important to make sure whether the fluid is corrosive.These are helpful for choosing the body material. This step is also used to ensure the safety of the valve staff.

 

To prevent actuator in the middle of over torque, This function not only protects the valve, but also protects the actuator itself. The torque is set by the setting device.

 

Actuator runs to close and open the limit position automatically stop (with a set of working modes).

 

electric actuator automatic detection of three-phase power supply terminal of the access, by the appropriate logic operation, the decision of the implementation of the operation of the mechanism when the AC contactor, in order to ensure the electrical connection to the right. If there is no automatic phase adjustment function, may be due to damage to the valve and connection order error, Because of the automatic phase adjustment function, the actuator power supply wiring can not consider the sequence.

 

When the actuator receives commands for the opposite direction, it automatically adds a time delay, to prevent unnecessary wear of the valve shaft and gear box.

 

Motorized valve actuator has a perfect power supply shortage protection function. It uses a combination of monitoring voltage and current method, It can't only detect the phase of power supply when the motor is at rest, also can detect the power shortage in the operation of the motor. So that prohibit motor operation, to avoid the lack of phase operation caused by motor overheating Notice:The vast majority of the motor phase is in the motor running process.
