New Compact Gauge Valve

Lightweight and compact, Swagelok’s (USA) new compact gauge valve is designed with a smaller footprint and for maximum performance. The design provides quick, convenient access for the isolation and venting of pressure gauges. The valve can be used with Swagelok pressure gauges. The pressure gauges are positionable with tube adapter ends, eliminating threaded connections and leak points.

The smaller, lightweight footprint reduces the need for supports, which place additional stress on a system. A streamlined body features Swagelok tube fitting end connections for leak-tight performance, reduced
installation time and cost, plus robust tube grip and vibration resistance.

The design incorporates a purge valve for easy bleeding of trapped fluid pressure between the valve seat and gauge upon shutoff. The purge valve is machined directly onto the body, eliminating potential leak points while allowing the user to safely release the fluid before removing the gauge. A permanently assembled purge cap is crimped to the valve body for operator safety and to prevent accidental disassembly.

“Gauge maintenance can be very time consuming and operators want to avoid unnecessary downtime with their process lines,” said Mike Adkins, product manager, valves for Swagelok Company. “By incorporating
both an integral purge valve and tube fitting end connections, we are reducing leak potential and installation time for greater efficiency.”

Available with either ½ in. or 12 mm Swagelok tube fitting end connections, the Swagelok compact gauge valve is constructed from 316 stainless steel. The valve is rated for temperatures up to 450°F (232°C) depending
on stem and packing. A soft-seat stem with PCTFE stem tip is available, and users can choose from UHMWPE, PFA, or PEEK packing. The valve is rated for pressures up to 4,000 psig (275 bar).
