Danfoss 034N0083 CPCE 15 Hot Gas Bypass Pressure Regulator 5/8 Inch ODF 406 PSI

Description

The Danfoss 034N0083 is a CPCE 15 hot gas bypass regulator designed to maintain evaporator pressure and refrigeration system stability during reduced cooling loads. Danfoss part number 034N0083 features 5/8-inch ODF solder connections, a factory pressure setting of 0.4 bar (5.8 psig), and a maximum working pressure of 28 bar (406 psig). Its pressure-responsive regulation allows hot discharge gas to bypass the condenser expansion circuit and enter the low-pressure side of compatible refrigeration and air-conditioning systems.

Technical Specifications

Information About 034N0083

The 034N0083 is a Danfoss CPCE series hot gas bypass regulator belonging to the manufacturer's pressure and temperature regulating valve product group. Its mechanical construction incorporates a pressure-operated regulating mechanism, 5/8-inch ODF copper tube connections, and an embossed flow-direction arrow for correct installation. The valve is designed for refrigeration systems requiring compressor capacity regulation through hot gas bypass, particularly when evaporator loads decrease below normal operating conditions. Its operating characteristics include a 0.4 bar factory setting, a 260 psi differential pressure rating, and a refrigerant medium temperature range from -50°C to +140°C.

Key Features:

• Hot Gas Bypass Regulation: Redirects compressor discharge gas to the low-pressure side to maintain evaporator pressure during reduced cooling demand.

• Valve Series: CPCE 15 pressure-operated regulator for refrigeration capacity control.

• Connection Size: 5/8-inch (16 mm) ODF solder connections on both inlet and outlet.

• Factory Pressure Setting: Preset to 0.4 bar (5.8 psig).

• Maximum Working Pressure: Rated for 28 bar (406 psig) refrigerant pressure.

• Maximum Test Pressure: Withstands specified testing pressure up to 31 bar (450 psig).

• Differential Pressure: Rated differential pressure of 18 bar (260 psi).

• Medium Temperature Range: Supports refrigerant temperatures from -50°C to +140°C.

• Flow Direction Indicator: Embossed one-way arrow identifies the required refrigerant flow direction.

• Injection Compatibility: Supports applications using an LG liquid-gas mixer for hot gas injection.

• Mechanical Regulation: Pressure-responsive operation without an external electrical power supply.

• Regulatory Approvals: cULus Listed, EAC, and applicable RoHS-related certifications.

The 034N0083 delivers the reliability and precision required for refrigeration capacity regulation, evaporator pressure stabilization, and hot gas bypass control under varying cooling loads.
