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 not include this feature to allow for stem removal to facilitate calibration through the valve.

- HB26: features a "hex" head screw, but no discharge/drain tube
