The JAMESBURY TORQ-HANDLE spring-return handles provide reliable automatic closing (or opening) of manual ball valves immediately upon release of the handle.
These handles may be held in the operating position either by hand, by a cable or by a fusible link option designed to release in the event of a fire.
A rugged, completely enclosed spring assures quick and automatic cycling of the valve to its designated failure position when the handle is released or the fusible link melts.
An electro-thermal link option is also available, to allow the handle to be released from a remote location.
TORQ-HANDLE spring-return handles are available completely assembled and tested on 1/4" through 2" (DN 8 through 50) ball valves, or they can be furnished separately, with a hardware kit for field mounting to existing valves.
They can be mounted to provide either spring-to-close or spring-to-open operation.
