Cast Steel Stainless Steel Electric Self-Operated Temperature Regulating And Control Valve
Product introduction:
ZZWPE Series self operated electric temperature control valve is an advanced temperature control equipment that combines the advantages of electric actuators and self operated temperature control valves, enabling automatic, fast, and accurate temperature control. Self operated electric temperature regulating valves are widely used in various industrial and civil fields, such as chemical, pharmaceutical, food, textile, heating, etc., to improve the energy efficiency and safety of equipment.
A self operated electric temperature control valve is to drive the valve body through an electric actuator, change the flow rate and direction of the fluid medium, and achieve the purpose of temperature control. Electric actuators are composed of servo motors, reducers, position sensors, etc., and have the characteristics of high precision and fast response. A self operated temperature regulating valve is composed of a valve body, valve core, spring, etc. It changes the position of the valve core by sensing the temperature changes of the fluid medium, thereby regulating the flow rate and direction of the medium.
In a self operated electric temperature control valve, when the temperature sensor detects a temperature change, it will transmit a signal to the electric actuator. After receiving the signal, the electric actuator will drive the valve body to change the position of the valve core to regulate the flow rate and direction of the medium. During this process, the function of the spring is to provide the original positioning force to ensure the stability of the valve core in its initial position. At the same time, the spring can also provide a certain restoring force when the valve core is disturbed, to ensure that the valve core can quickly recover to the correct position.

Product features:
1. Self operated electric temperature control valve can directly replace the temperature bulb and self-supporting regulating valve, no need to separately connect the temperature controller and actuator, it is the perfect combination of a regulating system and a self-support valve.
2. Single-phase AC power supply of AC220V and a temperature sensor to form a self-contained temperature control system for on site use.
3. The actuator has a highly integrated FDY-258T temperature control module, which combines the temperature controller and actuator to achieve mechatronics integration and simplify the temperature control system.
4. High control accuracy, fast response speed, stable and reliable performance, and long working life.
5. Wide adaptability range, capable of temperature control.
