Hex Valve HB59 Integral Block and Bleed Valve

Hex Valve's HB59 is a block and bleed valve designed for more critical services. It combines a fully packed, backseated block valve and a fully packed, backseated bleed valve into a single assembly to minimize connections, leak points, and installation time. The HB59  is typically used on applications where waste must be returned to the line or holdings vessel, most commonly with hazardous media or EPA-targeted hydrocarbons.
