The Danfoss 042H1126 is a 1-piece solenoid valve from the EVRA32 series, designed for use in a wide range of refrigeration and air conditioning applications. Here is a detailed description of its key features and specifications:
Design and Construction:The Danfoss 042H1126 solenoid valve boasts a compact, robust design, with a hermetically sealed body made of brass and a diaphragm made of PTFE. This material combination ensures excellent chemical resistance, making it suitable for use with various refrigerants and fluids. The valve is also available in several variants to cater to different pressure classes.
Operating Principle:This solenoid valve operates on the principle of a normally closed valve that opens when an electric current is applied to the solenoid. The valve's internal mechanism consists of a plunger that moves inside the coil when the current flows through it, which in turn opens the valve. When the power is turned off, the valve returns to its closed position due to the spring force.
Performance and Compatibility:The Danfoss 042H1126 solenoid valve can handle a maximum operating pressure of 13.8 bar (200 psi) and a maximum fluid temperature of 70 C (158 F). It is compatible with various refrigerants, including R134a, R407C, R404A, R410A, and R422D. The valve can be easily integrated into refrigeration systems, such as compressor units, condensers, and evaporators, to control the flow of refrigerant or other fluids.
Electrical Requirements:The Danfoss 042H1126 solenoid valve has a voltage range of 12V DC to 24V AC, making it suitable for use with various power sources. The valve comes with a 1.5-meter (5 feet) long wiring harness that includes a 3-pin connector for easy connection to the control system or wiring harness.
Installation and Maintenance:The installation of the Danfoss 042H1126 solenoid valve is straightforward. It should be mounted in a convenient location, preferably close to the fluid source and control system. The connection points for the power supply, fluid inlet, and fluid outlet should be properly sealed to prevent leaks and contamination. Regular maintenance, including cleaning and checking for leaks, is recommended to ensure optimal performance and longevity.
Conclusion:The Danfoss 042H1126 1-piece solenoid valve from the EVRA32 series is a versatile and reliable solution for controlling fluid flow in various refrigeration and air conditioning applications. Its robust design, wide compatibility with refrigerants and fluids, and easy installation make it a popular choice for professionals and DIY enthusiasts alike. With its excellent performance, durability, and energy efficiency, the Danfoss 042H1126 is an essential component for any refrigeration system.
