SV91 2-Way Normally Closed and Normally Open Floating Seal Construction Cryogenic Solenoid Valve Valcor Cryogenic Series © 2018 valcor engineering cORpORATION pH:973-467-8400 The SV91 series is a 2-way, direct acting, floating seal design solenoid valve for control of cryogenic fluids down to -454°F. it is available in normally closed and normally open configurations. the direct acting design is less prone to hang-up during operation and the floating seal has self wiping action for tight shutoff. The SV91 series has all welded joints eliminating external leakage. along with the standard construction, Valcor offers a high flow design and a design made specifically for Lco2. consult a Valcor application engineer for help in specifying a valve. The SV91 series is a rugged construction suitable for a variety of cryogenic applications such as the following: • Food processing/freezing • Backup system for biologic freezers • Environmental chambers • Dewar transfer • Gas chromatography • Fogging machines • cryogenic surgery equipment • Self wiping floating seal design for cryogenic fluids to -454°F • Direct acting design with no minimum operating pressure • All welded construction eliminates external leakage • Special constructions for high flow and LcO2 • Pressure rating up to 1200 PSI • Straight thru flow path yields high flow with less turbulence • Mountable in any position
