Analysis of the Characteristics of Electric Three - way Control Valve

The role of the fluid on the spool in the flow of state, so the work of good stability. In addition to the valve cover bushing at the guide, the spool side and the valve seat also has the role of the inner surface of the guide area, reliable work. Servo amplifier uses deep dynamic negative feedback to improve the regulation accuracy. There are many types of electric operator, suitable for 4 ~ 20mA.DC or 0 ~ 10mA.DC electronic electric valve can direct current signal to control the valve opening, without servo amplifier. Save on automation investment, and the single-seat, two-seater or sleeve valve compared to form the same system can save a valve to simplify the system and save investment. Bellows sealed valve stem on the move to form a complete seal, all the fluid leakage. More keyword search: Regulating valve
