Product Description

DOXI VALVE 

High Performance Teflon PTFE PFA FEP Lined/Lining/Coated/Seated Butterfly Valve
DOXI ® Teflon Butterfly Valves are a good choice for Anti-Corrosive Chemical Industrial solution!
Its special feature is the PTFE seat ring design. The interference between the PFA lined disc and the raised central area of the PTFE 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: PTFE Seat
Secondary Seal: O ring
Tertiary Seal: Taper PTFE seal ring
The through holes uniformly dispersing the disc surface make the Teflon material adhear to the disc perfectly possible.
The axle sleeves coated with ptfe material make lower torque of the valve to facilitate automation.
