Commercial refrigeration equipment depends on a tightly integrated system of flow control, motion control, and electrical switching components. For OEMs serving supermarkets, convenience stores, foodservice operators, and institutional kitchens, these parts determine how reliably a unit cools, defrosts, dispenses, drains, and cycles under demanding, continuous use conditions.
Deltrol Controls offers a wide variety of dispensing valves, solenoid valves, linear solenoid actuators, and relays commonly used in commercial refrigeration OEM designs.

Refrigeration Valves
Refrigeration valves are central to refrigerant management in reach ins, walk ins, merchandisers, ice machines, and prep tables. These refrigeration valves regulate refrigerant flow through expansion, suction, and discharge circuits, helping maintain stable evaporator temperatures and efficient compressor operation. In modern low GWP systems, precise valve performance is even more critical to ensure consistent cooling while meeting environmental requirements.
Deltrol Controls refrigeration valve is compact and economical. Designed to withstand refrigerants up to 180 degrees F and operating pressures to 300 psi. Materials selected for the refrigeration valve construction include lead free brass valve body, seal options include Neoprene & Viton. Standard coil voltages include 110/120VAC & 220/240VAC.
Dispensing & Drain Valves
Fluid handling inside commercial refrigeration equipment often involves dispensing and drain valves. These dispensing and drain valves manage water, meltwater, cleaning solutions, and beverage or ice outputs. Ice makers rely on them for fill and purge cycles; refrigerated beverage dispensers use them for portion control; and merchandisers depend on reliable drain valves to remove condensate during defrost cycles. Their ability to withstand harsh sanitation chemicals and constant cycling is essential for uptime.
Commercial refrigeration OEMs prefer Deltrol Controls dispensing valves for low pressure applications requiring high flow rates. Our media separated armature design protects critical components from corrosion and foreign debris. Common applications include tank draining, and ice making equipment.
Inlet Valves- Pilot Operated
When higher flow rates or pressure differentials are present, pilot operated inlet valves provide efficient control. These pilot operated inlet valves are common in large ice makers, filtration systems, and high capacity evaporator water supplies.
Deltrol Controls pilot-operated water inlet valves with multiple configuration options provide design flexibility for engineers. Features include multiple coil voltages, inlet/outlet port connections, and flow restrictors. Commercial refrigeration applications include water system distribution, and ice making.
Linear Solenoid Actuators
Mechanical motion inside refrigeration equipment is often driven by linear solenoid actuators. These linear solenoid actuators enable controlled movement for ice dispensing gates, bin level mechanisms, vending components, and damper controls. Their repeatable linear force ensures consistent operation even in cold, humid environments.
Deltrol Controls linear solenoids are available in both AC and DC coil voltages, pull or push style. We offer D-frame, C-frame, tubular, and magnetic latching designs. Common commercial refrigeration applications include door locks, and linear actuator.
Relays
Relays control compressors, condenser fans, evaporator fans, heaters, pumps, and solenoid circuits. By safely isolating low voltage control boards from high voltage loads, relays protect sensitive electronics and extend equipment life. Commercial refrigeration applications often require high power switching.
Deltrol Controls offers one of the most extensive power relay product lines in the industry. We also offer a complete line of general purpose, magnetic latching, buzzers, and clappers. Applications include compressors, and other high-power draw components.
