The Orbit Rising Stem Ball Valve offers a unique, highly-reliable valve with positive shut-off and repeated re-sealing capability. The key to the success of the valve is the rising stem that lifts the ball away from its seat before turning, so that the seats are protected from wear and degradation from the rotation.
Some of the key features of the valve are:
Multiple sizes and pressure ratings
Raised face flange
-50 deg F to 500 deg F (-45.5 deg C to 260 deg C) operating temperatures
Applications include hot oil systems, mole sieve dryers and equipment isolation
Unique design mechanically energizes seal by cam action
Single-seat design
Bi-directional sealing with zero leakage
Injectable packing
Self-cleaning
In-line repairable
