What Makes Victaulic Fire Protection Valve Systems Unique?

Since 1952, when Victaulic received the first UL approval for a grooved coupling for fire protection piping services, Victaulic has diligently continued with its mission to find faster and easier ways to join fire protection systems, eliminating the need for disassembling and reassembling components during installation.

Today, Victaulic technology includes a complete offering of fire protection systems, grooved couplings, fire protection pipe fittings, valves, devices, accessories and pipe preparation tools to meet the needs of any fire protection piping application. Victaulic valves in particular are engineered and manufactured for dependable, trouble-free performance, superior flow control and durable, long-lasting reliability.

As the originator and innovator of grooved coupling technology, Victaulic offers a variety of coupling sizes and styles for fire protection piping systems.  Our grooved systems are fast, clean and dependable ways of joining pipe as opposed to welding, threading, flanging and soldering.
