HANSEN Bulletin G359d <br /> NOV 2019 <br /> T E C H N O L O G I E S <br /> Specifications, Applications, <br /> Service Instructions & Parts <br /> BUTT WELD <br /> 1/211 through 1811 <br /> Globe & Angle <br /> for <br /> SHUT-OFF VALVES <br /> Refrigerants <br /> AW300H Butt Weld Angle Valve CRN CE <br /> Canadian Registration <br /> INTRODUCTION KEY FEATURES POLISHED <br /> These low pressure drop refrigerant shut-off valves STAINLESS <br /> are designed to be butt-welded directly to steel piping, STEEL STEM <br /> thereby eliminating potential leaky flanges or threaded <br /> joints and simplifying installation. Forged and cast steel <br /> bodies are lightweight,yet have substantial wall thickness <br /> to help overcome corrosion loss. The cast steel body <br /> is rigid, reducing the potential for seat leakage due to <br /> flexing of the valve body under abnormal conditions. I NON-LEAK <br /> The "heart" of Hansen shut-off valves is the patented SEAL PLUS <br /> non-leak seal plus packing design. This seal design is PACKING <br /> used exclusively on Hansen shut-off valves and virtually 1 <br /> eliminates stem seal leakage. \ <br /> APPLICATIONS <br /> Typical uses include: <br /> Ammonia refrigeration system suction,liquid, discharge, BALL BACK SEAT <br /> �BEARINGS �FOR SEAL / <br /> recirculating liquid,hot gas,thermosyphon,and oil lines, REPLACEMENT <br /> using handwheel or seal cap models. i <br /> ANTI-SPIN <br /> Steel pipe portions of halocarbon,commercial,industrial, /SEAT DISC <br /> and air conditioning systems, using seal cap models. <br /> TAPER SEAT <br /> Valves are also available for other fluids such as propane, <br /> propylene, and glycol with compatible seals. Contact ADDITIONAL FEATURES <br /> factory with specific fluid and application details for <br /> written approval. Globe and angle valves available. <br /> The low friction, no leak stem seal design permits the Low pressure drop design <br /> use of chain actuation for crossover applications without Interchangeable handwheel or seal cap. <br /> the need to retighten the packing. <br /> Teflon seat disc. <br /> Also available as Hand Expansion Valve. <br /> Chain actuators available (11/2" or 40mm and larger). <br /> Suitable for R717(ammonia), R22, R1 34a, R507a, R404a, <br /> R744 (CO2) and other Hansen approved refrigerants. <br /> 600 psig (41 bar g) SWP valves are available. <br /> Extended neck available up through 4" (100mm) for <br /> additional insulation clearance. <br />
