CONCENTRIC BUTTERFLY VALVE
A concentric butterfly valve is an extremely cost-saving choice for low-pressure applications and is widely used for many industries like water treatment, marine, fire fighting, HVAC and Agricultural.
Main Features:
Compact Design
With shorter face-to-face and light designs, it’s very space-saving for piping design compared to other valve types.
Low Emission and anti-blowout stem design
Packing made by pre-compressed flexible graphite rings, the roughness of the stuffing box and the stem is well controlled to ensure lower torque and better sealing. The live-loaded gland flange is available to adjust the compression of the packing seal. The space ring and gland design can prevent the stem to be a blow-out.
ISO 5211 Top Mounting
Lockable Hand Lever
Different End Connections Available:
Dead End Service
When the valves need to be installed at end of the pipe and one side has no connection with the ant pipe/flange, the valve needs a special design like threaded holes and bi-direction sealing.
