Valves
Gauge / Bleed Valves
Our gauge valves isolate pressure gauges and instruments from the process line, and the bleed version vents trapped pressure so a gauge can be removed or replaced safely. Built on our needle valve design, with a non-rotating hardened stem tip and metal-to-metal seat, they fit straight onto the tapping point with a male × female NPT body.
Pressure rating
Up to 6,000 psi
Materials
SS 316, carbon steel
Sizes
1/4" to 1" NPT
Versions
Gauge, gauge with bleed
Key features
Isolates the gauge from the process, so it can be serviced without shutting the line down
Bleed version vents trapped pressure safely before the gauge is removed
Non-rotating hardened stem tip and metal-to-metal seat, as on our needle valves
Male × female NPT body that fits straight onto the tapping point, 100% factory tested
