4S/4U Valves

Straight-Thru Valves

Category

The Glass-Trac Type 4 Straight-Thru Gauge Valve is available with screwed (S) and Union (U) gauge connections and used with Reflex and Transparent Gauges in working pressures up to 4000 psi. The “straight-thru” valve body design is popularly used with close hook-up (side connection) gauges because the gauge side connection centers and vessel centers can be identical. (With offset valves, vessel centers must be inside or outside side connection centers.) Type 4 Valves have a ¾” NPT Male Tank Connection as standard, with other connections available on order.

Type 4 Straight-Thru Gauge Valves are stocked in carbon steel with stainless steel trims. A molded Teflon packing ring is standard at no extra cost in valves for services to 450ºF. For temperatures to 700º F, valves have wire-graphite packing. The Type 4 Valve has stainless steel ball checks to shut off the flow automatically in case of gauge glass breakage. An optional back seating stem is available on request.
