The electric single-seat control valve is a top-direction single-seat control valve, which has the characteristics of simple structure, good sealing performance, large flow rate and reliable use. The effective and sufficient top guide system overcomes the vibration when the opening is small, and the effective service life is longer.
The electric single-seat control valve consists of an electric actuator and a single-seat control valve. There is a servo system in the electric actuator, no need to be equipped with a servo amplifier, the input signal and power supply can control the operation, the connection is simple, the spool of the regulating mechanism adopts the top guide, which is very suitable for strict leakage requirements, and the pressure difference between the front and the back of the valve is low. , And there is a certain viscosity and fiber-containing media.
Features of electric single-seat control valve :
1. The emergence of electric single-seat control valve is later than that of pneumatic control valve, but its use range is more and more extensive. Because no air source is needed, it is more convenient to install and use, and it can work as long as the power supply and the control signal are connected.
2. The electric single-seat control valve adopts a balanced valve body structure, which has small axial unbalanced force, large allowable pressure difference and good stability.
3. The sleeve is highly interchangeable, easy to assemble and disassemble, and easy to maintain.
4. The electric control valve is composed of two parts: electric actuator and control valve. Electric actuators have two types of linear stroke and angular stroke, which are combined with linear and angular stroke control valves respectively. For example, single-seat control valves, double-seat control valves, sleeve control valves, etc. are straight-stroke control valves.
