Product Detail

VITAL PFA lined butterfly valve is a full bore design to minimize pressure loss and provide maximum flow capacity. The flow port and internal parts are fully covered with PFA for excellent corrosion resistance.

Benefits
PFA liner is "locked-in" to body, disc, & stem. Eliminates liner collapse under vacuum.
Injection molded PFA lining is free from pinholes, cracks, swelling, and local uneven thickness
Excellent corrosion resistance due to PFA lining and TFM seats
More economic than a valve made from high-alloy materials
Low torque, smaller actuator, cost and weight saving
High flow capacity & unrestricted flow
Bi-directional bubble tight
Easy for actuator automation

Features
All wetted surfaces fully coated with PFA
2-piece off-center split body
Anti-blowout stem
Straight bore design
Durable TFM seat, zero leak
ISO-5211 mounting pad

Applications
Sulfuric acid
Nitric acid
Hydrochloric acid
Phosphoric acid
Chlorine
Bromine
Sea water
