1/4 in. Brass Ball Valve with Locking Handle
1/4 in. Brass Ball Valve with Locking Handle
The Apex Flow 1/4 in. Brass Ball Valve with Locking Handle (#940171L) delivers the same 600 WOG, full-port performance as the standard valve, with an added stainless-steel locking handle for lockout/tagout (LOTO) compliance. A padlock can be secured through the handle to prevent accidental or unauthorized operation — an essential feature for energy isolation procedures in industrial facilities, chemical plants, and utility systems.
