TRUE SINGLE UNION BALL VALVES TSU-P (PINNED) SERIES

Spare pin serves as a tool for valve servicing/repair
(remove from handle to assist in pin removal when servicing valve seat)
Praher's unique pinned 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.

TRUE SINGLE UNION BALL VALVES TSU-T (THREADED) SERIES

FEATURES

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.
