High Performance Features
• Double Offset Stem/Disc Design
– Reduced seat wear, zero leakage, and
low torque
• Blow-out Proof Stem
– Safety and ease of use
• Energized RTFE Seat
– Zero leakage, self-adjusting for wear
and easy field replacement
• Pressure Assisted, but not Pressure
Dependent Seat Design
– Optimal performance and sealing at
high or low differential pressures
• Adjustable PTFE Packing
– Packing can be adjusted while the
valve is in service
• Dead End Rating Equal to Nominal
Pressure Rating
– Allows the control valve to function as
an isolation valve.
