Danfoss 027B1120 Pilot Valve

The Danfoss 027B1120 is a high-performance EVM NC solenoid pilot valve engineered for precision on/off control within ICS Flexline, PM, and ICF large servo-operated main valves. This normally closed pilot valve facilitates reliable operation in demanding environments, supporting a maximum working pressure (MWP) of up to 65 bar (943 psig). Its versatile design allows for direct installation into the top cover of a main valve—eliminating the need for complex welding or separate pilot lines—or integration into a CVH housing for external pilot line applications.

Constructed with a robust steel body and stainless steel internal components, the 027B1120 is fully compatible with R717 (Ammonia), R744 (CO2), and non-flammable HFC/HCFC refrigerants. It features a technical kv value of 0.34 m³/h and is designed to operate within a temperature range of -60°C to +120°C (-76°F to +248°F). This pilot valve is intended for use with Danfoss solenoid valve coils, ensuring high-accuracy temperature and pressure regulation across all main valve sizes.

Key Benefits

• Universal Compatibility: Fits all sizes of Danfoss ICS, PM, and ICF main valves, simplifying inventory and field replacement.
• High-Pressure Capability: Rated for systems up to 65 bar, making it ideal for modern CO2 (R744) refrigeration transcritical and subcritical cycles.
• Direct Mount Design: Screws directly into the main valve assembly, reducing potential leak points and installation time for technicians.
• Durable Internals: Features PTFE (Teflon) valve seats and non-asbestos gaskets for superior chemical resistance and long-term sealing integrity.

Common Questions

Can the 027B1120 be used as a standalone valve?
Yes, when mounted in a Danfoss CVH housing, the EVM pilot can function as an independent solenoid valve for small-capacity applications or external control lines.

Is this pilot valve compatible with flammable hydrocarbons?
No, Danfoss does not recommend the use of this pilot valve series with flammable hydrocarbons; it is optimized for Ammonia, CO2, and standard HFC/HCFC systems.

Does the valve come with the required gaskets?
Yes, the 027B1120 is supplied with the necessary gaskets for immediate installation into the main valve cover.
