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 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…

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…

The electronic double-seat electric regulating valve realizes pressure compensation and valve shut-off by using two sealing lines on the valve core barrel to seal at the same time. The valve seat has upper and lower valve core balls. The thrust of the fluid acting on the upper and lower valve cores is opposite in direction but close in magnitude. The single-seat control valve is larger, but the le…

There is a wide range of valves available in the market for different purposes and applications. But when it comes to handling liquids with suspended solids, there is no better option than the Eccentric Plug Valves. These valves are considered to give high performance and are designed with high safety standards, yet they are economical. They also have higher rangeability, precise control, and h…

Double Block and Bleed Ball Valve: DBB Ball Valve is a combination of one or more block/isolation ball valves, and one or more bleed/vent valves, usually ball or needle valves. Double block and bleed valves operate on the principle that isolation can be achieved from both the upstream and downstream process flow / pressures. This is achieved by two ball, gate, globe, needle, etc.…

The accumulation of slag, dirt or any foreign matter in the pipeline may hinder the working efficiency of the plug valve and seriously damage the key parts of the valve. The inside of the pipe must be thoroughly cleaned with air or steam. When tapping the pipe, measure the size and length of the pipe thread to avoid filling the pipe with the valve seat and disc.…
