HB59 Series Block & Bleed
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, cost and installation time are also reduced. A 1/2" FNPT adaptor can accommodate a tube fitting for remote removal of bleed waste. The HB59 is typically used on applications where waste must be returned to the line or holding vessel, as is common with hazardous media or EPA-targeted hydrocarbons.
- 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
