Check valve (ZH)
Product Introduction:
When ventilation is on, positive pressure opens the blades. When ventilation stops, the blades or counterweight automatically close due to gravity, achieving a check valve function that prevents backflow. The opening angle of the blades depends on the wind speed. It features a simple structure, stable performance, flexible operation, and corrosion resistance.
Product Parameters:
Valve pressure resistance: 500Pa;
Applicable medium: Air, flue gas;
Leakage: Reverse leakage conforms to the airtight valve air leakage regulations in JB/T436.
Product Applications:
Installed in ducts
Keywords:
Damper and silencer

Metal shell (chip, array type) muffler
This type of silencer consists of silencing elements, a metal outer shell frame, internal support components, and connecting components. The silencing elements and shell plates are modular and assembled on-site. They can be quickly disassembled and reassembled, making disassembly and assembly convenient and facilitating maintenance and repair.
