Product Description


Lined Butterfly Valve

DOXI ® Butterfly Valves are a good choice for Corrosive Chemical solution!
Its special feature is the PTFE seat ring design. The interference between the PFA Lined disc and the raised central area of the seat ring shuts off the flow completely. The resilient elastomeric seat cushion ensures reliable shut-off for the life of the valve. 
The upper and lower positions of the seal ring, where the stem passes through, use a triple seal design to prevent leakage to the atmosphere.
Triple Seal Prevent Leakage
Primary Seal: Seat. 
Secondary Seal: O ring
Tertiary Seal: Taper PTFE seal ring
