Valves that have not been cycled for a period of time may have a higherinitial actuation torque. To increase service life, ensure proper valve performance, and preventleakage, apply only as much torque as is required to achieve positive shutoff.TestingEvery JB series needle valve is factorytested for bubble-tight shutoff at100 psi (6.8 bar) differential pressure.Shell testing is performed to arequirement of no detectable leakageat 1000 psig (69 bar) for valves withPTFE packing or 3000 psig (206 bar) forvalves with Grafoil packing.Cleaning and PackagingAll JB series needle valves are cleanedand packaged in accordance withSwagelok Standard Cleaning andPackaging (SC-10), MS‐06‐62.Options and AccessoriesAngle-Pattern ValvesInsert A after JB in an ordering numberwith B2, B3, and C dimensions listed.Example: SS-2JBABall Stem Tip MaterialAdd -CC for 440C SS or -ST for cobaltbasedalloy to the ordering number.Example: SS-2JB-CCRegulating StemsValves with 316 SS regulating stemshave a maximum flow coefficient (C v ) of0.24 (0.09 with 1/8 in. tube fitting endconnections).
