Block & Bleed - HB50 Series

HB50/51 Series Block & Bleed

Overview

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 the technician to direct the high pressure fluid away from himself before changing the instrument. The HB50 can also be threaded into a Hex Primary Block Valve (such as the Hex HG46) to provide secondary block and bleed functions on multiple instrument installations.

The HB51 Series is similar to the HB50 but utilizes a bleed screw in lieu of a bleed valve.

Features

  • Reduce Costs and Installation Time - Hex block and bleed valves minimize threaded connections while combining multiple valve functions.
  • Fully Backseated Bonnets - Prevent accidental stem removal and blowout. The unique design of our fully backseated bonnets minimizes emissions.
  • Non-Rotating Tip (NRT) Stem - Provides tight, repeatable shutoff without the galling or cross-socring that occurs on ball type stems. Because the NRT conical stem tip stops rotating when it contacts the seat, further torque turns the stem, but not the tip, protecting the tip from damage.
