Hex Options and Accessories

Purge ports are 1/8" FNPT plugged access ports on the inlet side of the shutoff valves on all Hex manifolds (except HM93/94). They allow for easy draining of impulse lines or the introduction of a purge gas or liquid seal without requiring additional tees and fittings.

Hex 1/8" Test Ports allow transmitter vent/test access, and are located on the outlet side of the manifold.

Integral tube fittings are an option if you use tubing with your instrument valves. An inverted nut and ferrule is pre assembled into the valve so you simply insert the tubing and tighten. They are available in single ferrule and double ferrule designs in Carbon Steel or 316 Stainless Steel. Available on HM10, HM13, HM18, HM45, HM50, HM53, HM57, HM58 and HN49.

Barstock hex head plugs are available in Stainless Steel or Carbon Steel in sizes: 1/8", 1/4", 3/8", 1/2" and 3/4".

Safety Handles can be utilized when there are concerns for safety, tampering or space limitations. A simple alternative to conventional T-handles, a tool is required to open or close the valve.

The Hex HK11 Universal Gauge Mounting Kit provides rigid mounting of a gauge while allowing simple maintenance and calibration. It enables horizontal or vertical mounting while providing additional support for the gauge. It also reduces the installation radius and number of components used, eliminating much of the cost associated with the large number of parts required for conventional gauge mounting.

Steam Blocks - The steam block option can be specified for processes that can thicken or solidify at ambient temperatures as is common with many chemical and petroleum products. Available on models: HM10, HM13, HM14, HM16, HM18, HM20, HM40, HM45, HM50, HM53, HM54, HM55, HM56, HM57, HM58 and HM56.

Integral Steam Tracing - Integral steamed trace manifolds are available for those critical temperature, gauge pressure or differential pressure instruments where greater heat transfer is required. These manifolds feature built-in steam passages within the manifold body to ensure maximum heat transfer capabilities.

Steam Jacketed Sample/Drain Valve - integrally-traced sample valves are available for use on sampling systems that require high temperatures to ensure a consistent liquid sample. Typically used on viscous liquids, slurries and products that tend to solidify when cooled or exposed to normal ambient conditions.

Hex Valve offers a bellows stem seal option for use on primary (root) valves as well as instrument valves for use with VOC's, hazardous materials or any application where leakage and containment are primary considerations.
