Marine chiller expansion valves regulate refrigerant flow in refrigeration systems, ensuring optimal cooling efficiency. They maintain precise pressure and temperature control within the system. These valves are crucial for reliable performance in marine environments.

Marine Chiller Expansion Valves:

- Size: 1/4" to 1" (DN6 to DN25)

- Grade: R22, R134a, R404A, R407C, R410A compatible

- Viscosity: N/A (flow rate dependent on refrigerant type)

- Buoyancy: N/A (not applicable)

- Material: Brass, stainless steel, or phosphor bronze

- Operating Pressure: 150 to 600 psi (10 to 40 bar)

- Temperature Range: -40°C to 120°C (-40°F to 248°F)

Marine Refrigeration Systems:

- Size: 1/2 HP to 100+ HP (compressor capacity)

- Grade: R22, R134a, R404A, R407C, R410A, or ammonia (NH3)

- Viscosity: Refrigerant-dependent (e.g., R134a ~ 0.2 cP at 25°C)

- Buoyancy: N/A (system-specific, refrigerant gas properties vary)

- Material: Copper, aluminum, stainless steel (piping), carbon steel (condenser/evaporator)

- Operating Pressure: 10 to 300 psi (0.7 to 20 bar) depending on refrigerant

- Temperature Range: -60°C to 80°C (-76°F to 176°F) for standard systems
