Offset OS&Y Valves
The Glass-Trac Type 7 Offset Gauge Valve features the Outside Screw & Yoke (OS&Y) design which prevents excessively hot and corrosive fluids from contacting stem threads. The stem uses the positive non-rotating stem principle and backs directly off the regrindable seat. This valve is offset for ease in gauge cleaning and is available in screwed (S) and union (U) gauge connections. The Type 7 Valve also has a backseating stem as a standard feature. Stainless steel ball checks are available upon request.
