Types and working principles of common flow control valves
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 can also be called a full-function valve
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".… -
Installation method and application skills of positive and negative angle control 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 diaphragm three-way control valve parts material
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 … -
Key points of structural design of pilot-operated Sleeve control valve
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.… -
What are the pneumatic diaphragm single-seat control valves, and how are the control valves classified?
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… -
Features and working principle of self-operated temperature control valve
The self-operated temperature control valve is composed of a temperature sensor and a control valve. It is an energy-saving product that does not require external energy and uses the temperature change of the controlled medium to automatically adjust. The product is suitable for various gases, steam, hot water, Automatic temperature control in various heat exchangers where oil, etc. are the medium… -
Installation and maintenance of self-operated pressure regulating valve
Self-operated pressure regulating valve does not need external energy, uses the energy of the medium to be adjusted as the power source, introduces the actuator to control the position of the valve core, changes the pressure difference and flow at both ends, and stabilizes the pressure before the valve (or after the valve). It has the advantages of sensitive action, good sealing performance and sm…
