Gauge Valves with Single Vent Port, Needle Pattern – H Series
*PRODUCT IMAGE IS REPRESENTATIVE PROVIDED BY THE MANUFACTURER. DO NOT MAKE BUYING DECISIONS SOLEY BASED ON THE IMAGE. PLEASE VERIFY SPECIFICATIONS MEET YOUR REQUIREMENTS.
Parker's single block gauge valves with vent are needle type valves designed for safe and reliable control of flow into a wide range of measurement and analysis instruments such as pressure gauges, pressure transmitters and pressure switches. These gauge valves also allow for venting/draining of any process media that may be trapped, following isolation of the instrument for maintenance and/or removal purposes.
Parker's gauge valves are available with a wide array of connection types and sizes. For the ultimate in safety, reliability, speed, and ease of installation all valves can be specified with integral tube connections utilising Parker A-LOK® (Two Ferrule) or CPITM (Single Ferrule) compression fitting technologies. This will also ultimately reduce overall user costs. As standard, gauge valves are offered with the traditional external thread and nut or inverted (internal thread) design to inlet and outlet connections. They can also be supplied with integral swivel gauge adaptor to the outlet through a socket weld, generally conforming to ANSI B16.11.
The valves have a 1/4" NPT side port for the optional fitting of a captive bleed/vent valve or a blank plug. When a tube connection is required, Parker’s unique PTFree connectTM option to the side port is recommended. This system enables users to assemble tube lines without the need for PTFE tape or liquid sealant.
