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.…

Monel alloys, cast nickel alloys, Hastelloy, etc. are all materials used to manufacture special purpose valves. Nickel Alloy: Also known as Monel alloy, it is an alloy made of metal nickel as a matrix by adding copper, iron, manganese and other elements. Monel is a high nickel-copper alloy with good corrosion resistance. Monel alloy is a Ni-Cu alloy in nickel-based corrosion-resistant alloys. …

The safety valve is a special valve that is in a normally closed state under the action of external force. When the pressure of the medium in the equipment or pipeline rises beyond the specified value, it discharges the medium to the outside of the system to prevent the medium pressure in the pipeline or equipment from exceeding the specified value. . Safety valves are automatic valves, mainly use…
