Parker Hannifin HGVS8PBV Gauge Valve Plug Bleed Valve

The Parker Hannifin HGVS8PBV Gauge Valve Plug Bleed Valve is a compact, purpose-built device that provides a controlled outlet for venting or purging pressure from a gauge line in hydraulic and pneumatic systems, enabling safe depressurization during installation, testing, or maintenance of instrumentation. It uses a 1/2 inch NPT threaded connection to mate with standard gauge ports and fittings, delivering a straightforward, leak-tight bleed path without requiring adapters or custom hardware. This part, identified by the HGVS8PBV designation within Parker's HGVS gauge valve family, is designed for plug-type bleed operations—placing a dedicated bleed point directly on the gauge line to relieve residual pressure efficiently. Ensure the 1/2 NPT port matches your system and that the bleed valve is suitable for your process fluid and operating conditions to support reliable, repeatable gauge maintenance and safe servicing of instrumentation lines.
