About Spring Return Handle Ball Valves
ZIPSON'S SH0 1, spring return handle (also called dead man handle) was well designed as heavy duty type for very long term operation. The
most characteristic of SH01 is with locking device for option.
The SH01 is designed to mount upon the ISO 5211 direct mounting pad. This will be very
convenient for user to replace the handle from normal type to SH01, and repair the handles
after long term operation without throwing the whole valve set. And it's very economic to stock the spring handles only.
Valve with dead-man handle can be for normally close or open, it is to prevent operator from forgetting turn the valves back to open or close. And this may cause problem or danger for  the system. Zipson SH01 have locking device for option. Only for the right one to turn the valves.

3-piece sanitary ball valve/ 207S, 2-piece flanged ball valve/ 110F/ 110T, top-entry ball valve That's allow users wisely to stock valve & spring handle separately.
