- Handle can be used as tool to adjust threaded seal carrier.
Praher's unique spanner wrench handle provides for easy valve seat servicing - just pull handle off ball stem & use as a tool (see picture). Praher's unique threaded true single union ball valve design provides for:
- user friendly handle operation - union nut load does not transfer onto ball seat, thereby providing user with easy handle operation even if valve not operated for a long period of time.
- "below grade - blocked seat flooded suction design" - valve seat will not blow out from static pressure if union nut removed.
