Features & Benefits
Substantial PFA liners for 3″ through 12″ sizes and PTFE liners for 14″ through 24″ size. Benefit is resistance to permeation leading to extension of product life and operator safety because of lack of atmospheric leakage.
Live loaded stem sealing system. Benefit is atmospheric sealing integrity and no manual adjustment over the life of the valve.
Low torque. Benefit is smaller operators taking up less space, ease of operation and cost savings with less expensive automation packages.
Improved disc design leading to less deflection at higher pressures and tighter in-line seal
ISO 5211 Actuator Mounting Pad for standardized actuator mounting
Live loaded self-adjusting shaft seal with triple O-ring protection
Blow-out proof shaft design for additional operator safety
Extended body and disc liner above the shaft seals provide optimum protection of the O ring shaft seals from corrosive media
PTFE atmospheric seal protects internal components from atmospheric corrosion and provides locating ring for actuator mounting
Fully encapsulated bottom shaft eliminates potential leak path at bottom of valve and eliminates the necessity for further sealing elements
