The Kerotest Double Block & Bleed Needle Valves are built for applications with pressures up to 10,000 psig (689 bar). The design combines isolation and venting in a single valve, eliminating the need for tubing and fittings. This operator-friendly valve design features fully captured stems, consistent sealing during system depressurization or repressurization under a range of pressures, and a low-torque, easy-turn ergonomic handle.
