New all-stainless-steel cryogenic solenoid valves come in two configurations — SV91 Series, and SV95 and SV97 Series — in normally open and normally closed models. Fluid temperature range is 450 to 400°F, depending on the valve. SV91 valves use a shear-seal design — a gate-type configuration for optimal flow rate with minimum turbulence. The unit's small size and low-power consumption make it suitable for high-volume cryogenic transfers, thermal chambers, and bleed valves. The SV95 and SV97 Series are poppet-style valves for high-cycle applications. Designed with constantload Teflon or PFA seal disks, the valves deliver bubbletight shutoff.
