3A-S/3A-U Valves

Product Description

The Glass-Trac Type 3 Offset Gauge Valve has the Outside Screw & Yoke design which prevents excessively hot and corrosive fluids from contracting stem threads, causing possible malfunction. The stem backs directly off the regrindable valve seat using the positive, non-rotating stem principle. The valve is offset for ease in gauge cleaning and comes in both screwed (S) and a union (U) gauge as standard. On special order, tubular (T) gauge or other type connection can be supplied. Type 3 valves are used with Reflex and Transparent Gauges in working pressures up to 4000 psi.
