      Electric control valve|Pneumatic control valve|Pneumatic shut-off valve|Self-operated regulating valve

      The electric regulating valve is a commonly used regulating valve type and is an important execution unit instrument in industrial automation process control. With the increasing degree of automation in the industrial field, more and more applications are being applied in various industrial production fields. It is suitable to install the upper end of the working piston in the lower part of the horizontal pipeline. The temperature sensor can be mounted in any position and the entire length must be immersed in the controlled medium. The electric regulating valve mainly relies on the electric actuator to drive the opening and closing of the regulating valve. The electric actuator can accept the analog signal from the current or voltage of the control system, and adjust the parameters such as the flow rate and pressure of the pipeline medium by controlling the different opening degrees of the regulating valve. Purpose, to achieve remote automatic control.

      Pneumatic shut-off valve adopts lip-type elastic sealing ring structure design to ensure the reliability of sealing. For low-pressure, ultra-low pressure or vacuum working ball valves, the leaf spring-loaded valve seat sealing structure can ensure the long-term reliable sealing of the ball valve. The seat material of medium and high temperature ball valves can be selected from para-polyphenyl or metal materials. It can be used with solenoid valve and valve position switch box to realize remote cut-off control. The pneumatic shut-off valve is powered by compressed air. The valve stem drives the valve core to rotate 90° in the valve body to achieve full-open-closed action. The pneumatic shut-off valve can be divided into soft sealing seat and metal sealing valve according to its sealing performance. seat.
