Bellows Stem Seal Option
Hex offers a bellows stem seal option for use on Hex instrument valves in the control and monitoring of corrosive chemicals, hazardous materials or any application where leakage and containment are primary considerations. The bellows stem seal option can be specified on a wide range of Hex...
Bleed Valves - HB24 Series
The HB24/25/26/27 Series Bleed Valves are available individually, or optionally threaded into an unused outlet port on a variety of Hex Valve models. Used for bleeding off high pressure media, the HB24 & HB25 incorporate back-out stops to prevent inadvertent removal of the stem; the HB26 does...
Block & Bleed - HB50 Series
The HB50 features a fully packed and backseated block valve along with a bleed valve with directional discharge tube and stem stop. WIth a gauge or transmitter threaded into its outlet, the HB50 will allow pressure to be bled and blocked for simplified instrument removal. The discharge tube enables...
Block & Bleed Tee - HB52 Series
The Hex HB52 Bleed Tee is ideal for modernizing outdated, non-bleed gauge installations. During instrument maintenance, simply thread the HB52 into the outlet of an existing block valve. An instrument is then threaded into the HB52 outlet to complete the installation. A second 1/2" side outlet...
Block & Bleed - HB59 Series
For more critical services, the HB59 Integral Block and Bleed Valve combines a fully packed backseated block valve and a fully packed backseated bleed valve into a single, streamlined assembly that minimizes threaded connections. A major benefit of this design is that, while minimizing connections...
Gauge/Block Valves - HG35 Series
The HG35 gauge valve, with a male inlet and a male outlet, meets the applications requirement for a block and bleed valve without the need for a close nipple when connecting to a female port on a gauge pressure transmitter rated to 6980 psi. Other manufacturer's generally supply 1/2" NPT female...
Gauge/Block Valves - HG46 Series
Compared to traditional piping methods using gate valves, tees and nipples, the HG46 provides a quick, inexpensive and compact means of installing gauges and static pressure instrumentation. The use of the HG46 also reduces the number of threaded connections, resulting in fewer potential leak...
Gauge/Block Valves - HG47 Series
A roddable, hard seated orifice valve that overcomes the drawbacks of conventional valve designs. Ideal for use on high temperature, viscous services, the HG47 provides full port, unrestricted flow. The HG47 features an OS&Y bolted bonnet with weld or threaded connections. The accessible hard...
Gauge/Block Valves - HG48 Series
The HG48 gauge/block valve provides three outlet connections to facilitate the mounting of gauges and other static pressure instruments in a variety of positions. The design creates a compact installation with fewer leak points as compared to conventional mounting requirements due to the reduced...
High Temperature - HT01 Series
Hex HT03 and HT01 high temperature globe valves are designed for service to 1500°F at 500 psi working pressure. They are available in sizes up to 1-1/2" with NPT, socket weld, butt weld or flanged end connections. Hex high temperature valves are used as shutoff or block valves, as well as bleed...
Gauge Syphons
Hex gauge syphons act as thermal and liquid seal barriers between hot process vapors (such as steam and heat transfer fluids) and the gauge pressure instrument. It is designed to replace the large installation space requirements of the traditional "pigtail" syphon, providing maximum instrument...
