Product Description

Product Description

DOXI VALVE 
Lined Butterfly Valve
DOXI ® Butterfly Valves is a good choice for chemical solution!
Its special feature is the seat ring design. The interference between the 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
