Pneumatic membrane single-seat control valve can be divided into 5 aspects, namely according to use and function, medium working temperature, pressure, special purpose and according to principle, function and structure. Pneumatic control valve is to use compressed gas as the power source, the cylinder as the actuator, and with the help of valve positioner, converter, solenoid valve, position reten…

The pneumatic single-seat regulating valve is composed of a pneumatic multi-spring diaphragm actuator and a low-flow resistance single-seat valve. The new type of actuator has a low height and low weight, and is easy to install and calibrate. The new valve body has a compact structure, a smooth flow channel, and a large flow coefficient. . In order to achieve interchangeability, the pneumatic sing…

Pneumatic regulating valve is composed of pneumatic actuator and regulating valve.…

Electric regulating valve is a device suitable for flow regulation in computer monitoring system. Generally used in unattended thermal stations. Electric regulating valve consists of valve body, driving mechanism and transmitter. The temperature control valve is a device for self-operated flow regulation through the temperature sensor package, and does not require an external power supply; while t…

The control valve has eight functions in total, and the eight functions of the full-function ultra-light control valve are excellent, so it is called "full-function valve".…

The angle control valve has a simple flow path and low resistance, and is generally suitable for forward use (installation). However, in the case of high pressure drop, it is recommended to use the angle-type control valve in reverse to improve the unbalanced force and reduce the damage to the valve core, and at the same time, it is also beneficial to the flow of the medium and avoids coking and c…

Pneumatic membrane three-way control valve adopts cylindrical thin-walled window-shaped valve core guide, which is different from the bushing guide of plunger-shaped valve core. Equipped with multi-spring actuator, it has the advantages of simple structure, light weight, small volume and convenient disassembly and assembly. and other advantages. It is widely used in the process of precise control …

The pilot-operated sleeve control valve has been widely used in automatic control systems due to its small size, compact structure, good sealing effect, high shut-off capacity (up to nominal pressure), wide application range and long service life. . The valve can be used as a vent shut-off valve, especially for high temperature, high pressure and large-diameter shut-off applications.…
