The 091-400C210/120LZ is a horizontal-body Rotalock compressor service valve sized for a 1 inch - 14 TPI Rotalock thread with a 5/8 inch sweat compressor-side connection, 7/8 inch sweat line-side connection, and a 1/4 inch SAE flare service port on the LEFT side. This is the type of service valve installed at the suction or discharge port of a semi-hermetic refrigeration compressor (Copeland, Emerson, Bitzer, Carlyle, Frascold) where the refrigeration technician needs to isolate the compressor from the system AND have a service port available for gauge readings, refrigerant recovery, evacuation, and charging. Rotalock service valves are wear parts in commercial refrigeration. The schrader cores fail, the packing nuts loosen, the seats erode from repeated isolation cycles. A failed Rotalock valve means a compressor that cannot be serviced without pumping down the entire system. For supermarket refrigeration racks, walk-in cold storage, ice plants, food processing facilities, and industrial chillers, having spare Rotalock valves on the truck or on the shelf is the difference between a four-hour service call and a four-day shutdown. The 1-14 Rotalock thread with 5/8 x 7/8 sweat configuration is one of the most common combinations in commercial refrigeration, sitting between the smaller 1/2 x 5/8 valves used on light commercial and the larger 1-1/4 x 1-1/8 valves used on heavy industrial. This valve fits the medium-duty range that covers the majority of supermarket rack circuits, walk-in condensing units, and commercial ice machines. King Surplus has 644 units of this Rotalock service valve available, brand new in the box, sourced from Refrigeration Sales, Inc. surplus. Single units ship same or next business day from Texas. Substantial volume pricing available for HVAC and refrigeration wholesale distributors, supermarket facility managers, refrigeration service contractors, and industrial cold storage operators stocking spare parts.
