Components

Swagelok pneumatic on / off valve -40 confirmed with Swagelok Sample Tested! Swagelok SS-4 UW-VCR-TF valve Swagelok® U series bellows-sealed valves enhance reliability, versatility, and safety—with a secondary containment system that prevents leaks to atmosphere even if the primary seal fails. ■ Gasketed or welded body-to-bellows seals ■ Stem tips for shutoff or regulating service ■ Flow coefficients (Cv) from 0. 36 to 5. 3 ■ Variety of end connections: ■ Swagelok tube fittings— 1/4 to 1/2 in. and 6 to 12 mm ■ Tube socket weld ends— 1/4 to 3/4 in. ■ Tube butt weld ends— 3/8 to 1 in. ■ Female VCR® face seal fittings— 1/4 and 1/2 in. 1) Leak rate checked “out of the box” 2) 50 cycles (no pressure) 3) 20 Cycles (20 Bar Ar) 4) Leak rate checked 0, 20, 50, 100, 150, 190 Bar Using the PHOENIXL 300 He Sniffer: Lowest detectable leak rate for helium < 5 x 10 -12 mbar l /s All Measurements: q PHe=200 bar 5 x 10 -12 mbar l /s Robert Becker/Theodoros Katopodis 11/5/2020 12

Swagelok M 31 Metering Valve Used in LHCB!

Swagelok G 42 Ball-Valve Testing Every 40 G series and 40 series ball valve is factory tested with nitrogen at 1000 psig (69 bar) or at its maximum rated pressure if less than 1000 psig (69 bar). Seat tests have a maximum allowable leak rate of 0. 1 std cm 3/min. Used extensively in LHCB! To prevent any “leak-through” this purge valve is also capped

Model: 600 -9 LT ½” Tube Model 600 -9 LT/ 316 SS/ ½” VCR/ 25’ Cable/ Remote 9500 Electronics/ Flow Rate and Total Display/ 4 -20 m. A Output Sample Ordered Accuracy: 0. 5% of Full Scale or 2% of reading - whichever is better Repeatability: Better than 0. 2% of reading Response Time: Liquids less than 1/2 second, Gases 1 to 2 seconds typical (4 to 8 seconds worst case) Pressure Drop: Negligible - completely unobstructed straight thru flow path Flow Element: Construction meets NEMA 4, 7 & 9 explosion proof requirements Flow Wetted Parts: 316 S. S. standard, also many exotic metals and coatings available to suit requirements Calibration: Liquid CO 2 Line Size: ½” Tube Flow Range: 1 – 24 grams/second Temperature: -40°C Pressure: 100 Bar Delivery: 4 – 6 weeks F. O. B. : Trevose PA Operating Principle: The Model 600 -9/9500 operates using a constant temperature system that employs two RTD sensors: one for sensing temperature, and one for sensing flow. The flow sensor is heated to a precise temperature above that of the fluid passing by. The fluid conducts heat off the sensor in direct proportion to the mass flow rate. The temperature sensor is used to set the heat on the flow sensor and correct changes in the fluid temperature. Thermal Instrument's thermal mass flow meters consist of one piece; a flow element with a bridge controller, signal conditioner with power supply, flow signal, A/D converter, linearizing network, 4 -20 MA DC, flow output, operational flow display, and totalizer.
