Butterfly Valve
J-VALVES
Structural Features
Cast Steel Material: The valve body is made of cast steel, which has high strength and good corrosion resistance. It can withstand relatively high working pressure and temperature, and is suitable for a variety of media.
Lug-Type Structure: Adopts a lug-type design. The bolt holes at both ends of the valve body allow for easy installation and disassembly, eliminating the need for flange connections. This reduces installation space and costs, while also facilitating maintenance and overhaul.
Soft Seal Design: Uses soft seal materials such as Nitrile Butadiene Rubber (NBR) or Polytetrafluoroethylene (PTFE), which offer excellent sealing performance and chemical corrosion resistance. It is suitable for a variety of media, including water, air, and oil.
Valve Stem Sealing: The valve stem is equipped with a specially designed sealing structure to prevent medium leakage and ensure operational safety.
Flexible Operation: Equipped with a manual or pneumatic operating mechanism, it is easy to operate and can quickly realize the on-off control of the valve, meeting different operational needs.
