Product flow flushes any foreign material away from the seat without localized, high velocity erosive flow. LONG LIFE. Orbit Valves replace troublesome ball Valves , gate Valves , globe Valves and plug Valves . The Orbit design has performance advantages that reduce plant outage and minimize the cost of ownership.

NOTE: Never remove any part from an Orbit valve unless specifically instructed to do so in Orbit literature, or without first consulting an Orbit Representative. Incorrect procedure could result in personal injury and/or property damage. 2 ORBIT. CT-ORB-TEC/REF/2.
