Valve body is heavy duty.
Optimal disc geometry and cavity free flow passage offers minimum flow re-
sistance and high Cv values.
Heavy duty pins connecting valve shaft to disc avoids lost motion under high
torque conditions.
Long life, easy field replaceable seat placed in body, away from flow stream,
provides bubble tight shut off. Valves are equally suitable for control and tight
shut off applications.
Low friction bearings provide maximum radial support for higher shaft loads.
The PTFE lined bearings having low co-efficient of friction minimizes operat-
ing torque and reduces actuator size. They are slip-in place type, easy for
assemble and disassembly.
Seat option includes Reinforced PTFE (15% Glass Fiber/12% Carbon/3%
Graphite), EPDM, NBR, FPM soft seats and Flexible Metal Seats to suit a vari-
ety of fluids and applications.
