for High Pressure
Unexcelled in workmanship, material and design. Made with metal-to-metal joint between top and bonnet, with another leakproof joint around the valve stem. The disc is held in place by a bronze noncorrosive spring, and the tension at all times holds the composition disc against the upper seat, making leakage impossible under all circumstances. The disc holder, which holds the composition disc forming the lower seat in the valve, is spun on the disc carrier in such a way that it may revolve, and allows the carrier to take its seat properly when closed.
The Syracuse Packless Standard Globe Valve is of bronze
and is especially adapted for high pressure steam systems. Send for "Inside Information on The Syracuse Packless Radiator Valve"
