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.
Features/Benefits:
- Block valve isolates the downstream process fluids, and the bleed valve exhausts upstream fluids, enabling instruments to be removed without disturbing the permanent piping installation on the bottom
- The ¼” NPT bleed plug is located 90 degrees to the left and may be removed and replaced with exhaust piping to direct the fluids to a safe location
- DPE dust cap for bonnet and stem (non-packing)
- Body and bonnet material: ASTM A182 F316 stainless steel or A105 carbon steel
- Finish: Stainless steel is passivated; Carbon steel is zinc plated
