GAUGE VALVES
Overview
GAUGE VALVES provide reliable isolation, venting, and block-and-bleed functionality for pressure gauges, transmitters, switches, and instrumentation devices. Designed for safe gauge removal, calibration, and system isolation, ACE gauge valves are manufactured from 316/316L stainless barstock and engineered for high-pressure, high-temperature environments.
All ACE gauge valves are fully interchangeable with Swagelok®, Parker A-LOK/CPI®, SSP®, Tylok®, Ham-Let®, DK-LOK®, and Superlok®, ensuring cross-brand compatibility for OEM panel builders, analyzer systems, and process instrumentation loops.
Available in inline, angle, block-and-bleed, and vented configurations up to 10,000 PSI.
