ULTRA Seal
ULTRA is an engineered fluorocarbon polymer that is rated for 500°F. Excellent for handling aggressive fluids at
high pressures, ULTRA is recommended for extended service in hostile environments involving chemical, thermal,
and mechanical stress. ULTRA has excellent thermal stability and is ideal for steam, hot gases, and a variety of
process chemicals where service can also be subject to pressure cycling.

Operator Information
Valves up to 6" CL150, 4" CL300, and 4" CL600 full port (or corresponding one size larger valve with reduced port) can
be supplied with locking handle. All valves can be mounted with gear operators for manual operation. All valves can be
mounted with actuators such as DelVal Series 21 rack & pinion pneumatic actuators or DelVal Series 25 scotch yoke
pneumatic actuators (see respective actuator brochures for further details) and other automation accessories such as
positioners, solenoid valves, limit switches, manual overrides, etc. for complete assembly.
