[Produktbeschreibung]

Product Overview：
PUMASON produced electric control valve is the automated production process medium flow control system is one of the most important products, it is widely used in various fluids and process conditions of the automated process control system.
PUMASON provides electric control valve, is currently the latest generation of control valves, the use of IEC international standard. Installation height than other products by 30%, flow coefficient Kv is increased by 30%, material saving energy. There are many types of design and connection flange spacing. Action also has reliable performance and accurate flow characteristics, adjustable range, seat leakage rate is small, stable operation. Multi-spring actuator design. Thus, the unique advantages of this product will be widely used in various industrial sectors to achieve quality control in effect and economic benefits.
Structural features：
PUMASON provided by the electronic type electric control valve and electronic actuator valve with low flow resistance through a combination.
1.Actuator：
1.1 Works：
When the actuator control portion receiving the signal from the controller (input signal 4 ~ 20mA.DC or 1 ~ 5V.DC) and from the opening part of the opening detection signal, and comparing the two signal amplification, to eliminate the difference between the direction of the thrust generated by the motor drive and control, by connecting to the drive spool movement, thus changing the flow valve and valve seat area, until the two parts to eliminate bias, the motor stops working, spool stop motion, in order to to automatically adjust and cut off purposes.
1.2 Features：
PUMASON produced by high-performance electric actuator. Machine with servo system without reprovisioning servo amplifier, controller, key components of advanced hybrid integrated circuit, and cast resin curing, the aging treatment, high reliability, moisture, shock; adjust the zero potentiometer, stroke, sensitivity, convenience easy; with the function switch to choose the positive and negative action, select the signal off the three states. At the same time, the executing agency with overload protection, temperature protection and compression springs ensure tight valve closure protection.
2. Body components：
PUMASON electronic electric control valve from the valve body, valve, stem, seat, bonnet, actuator and other basic components.
3.Optimization considering：
When the pressure is greater than 1.5MPa, 250 ℃ when the temperature is higher than the sealing surface should be surfacing wear-resistant alloy to improve the reliability and service life of the sealing surface. When compared with poor working conditions, working pressure greater need for smaller size and weight of the medium is not clean or work in the occasion, suggested the use of full-function ultra-light control valve.
