SUPERFREEZE well-designed and constructed low pressure drop refrigerant stop cum check valve are butt-weldable directly to steel piping, thereby eliminating potential leaky flanges or treaded joints, and simplifying installation. The important features of these valves are non leak packing and back seat design. In valve open condition, if inlet pressure drops below outlet pressure, the valve acts as check valve and do not allow reverse flow of liquid.


Refrigerants : Suitable for all common refrigerants including R-717 (Ammonia), R-134a, R-404, neutral, gaseous and liquid media
Temperature Range : -46oC to +116oC (-50′ F to 240′ F)
Temperature below : -60 F at lower pressure

Leak proof sealing : Non Metallic special polymer seal and taper seat provides leak proof sealing.
Back seating & gland packing : The heart of SUPERFREEZE shut-off-cum valve is the Patented stem packing
and backseat design
. This Patented design is used exclusivelySUPERFREEZE valves and virtually eliminates stem leakage.
