High Pressure Equipment Company has developed a line of block and bleed needle valves that deliver safe, reliable operations up to 20,000 psi. These needle valves are offered in both single and double block and bleed configurations. Both valve styles have Type 300 stainless steel tee handles with a non-rotating stem design, as well as optional wetted parts and O-rings. HiP’s (MVBB series) single block and bleed needle valves provide a small valve body/package and Teflon packing up to 400 °F (204 °C) with tube sizes of 1/4 inch, 3/8 inch , 9/16 inch medium pressure and 1/4 inch, 3/8 inch and 1/2 inch FNPT. The MVBB series is designed for calibration operations by providing controlled flow to high-pressure hydraulic and pneumatic systems through both shut-off regulation and diversion. HiP’s (DBB series) double block and bleed needle valves are manufactured from cold-worked stainless steel and 17-4-H1075, with 1/4-inch to 1-inch medium pressure, coned and threaded connections and Teflon packing from 0 °F (-17.8 °C) to 400° F (204 °C). The DBB series is designed for pressure monitoring and testing, chemical injection and drain line isolation applications.
