CVA Range Catalogue (P110) - 31135 CVQ

Quarter-Turn Actuator

785 9 6

5 Hand Drive 7 Geartrain

Optional hand drive mechanism can be provided with both linear and quarter-turn actuators to allow manual operation of the valve. Simple yet durable high efficiency spur gear drive, lubricated for life with proven high reliability.

8 Anti Back-Drive Mechanism 6 Terminal Bung - Double-Sealing

The CVA standard build is capable of resisting any back drive from the valve up to 125% of the rated force. For applications where loss of power requires increased “fail-in-position” capability, an optional solenoid locking mechanism is available. The “double-sealed” terminal compartment provides a compact wiring interface for power, control and feedback indication. Four conduit entries are provided as standard with internal and external earth connection points. Control and indication circuits can be supplied certified to “IS”. Double- sealing is important as the terminal compartment is then segregated by a watertight seal from the rest of the actuator. Even if the cover is left off during installation or conduit entries for cable glands are not properly sealed, the actuator remains fully protected.

9 Output Drive

For CVQ the base conforms to MSS SP-101 or ISO 5211. CVL may be adapted to suit individual valves.
