Danfoss 060-121966 Pressure Control

The Danfoss 060-121966 KPI35 Pressure Control is an industrial-grade electromechanical switch designed for the regulation, monitoring, and alarm signaling in liquid and gaseous media systems. Built for durability in commercial HVAC, boiler, and pump applications, this low pressure switch features a SPDT contact system that manages motor starters and solenoid valves with precision. It operates within a pressure range of -0.2 to 8.0 bar, utilizing a high-performance bellows system to ensure setpoint stability even under vibration. The adjustable differential range of 0.4 to 1.5 bar allows for fine-tuning system cycling to prevent short-cycling of compressors or pumps. With its G 1/4 A pressure connection and IP30-rated enclosure, the KPI35 is compatible with water, air, and non-corrosive gases. Contractors favor this 060-121966 model for its snap-action contact system, which reduces arcing and extends the service life of internal components, ensuring reliable HVAC pressure regulation in demanding environments.

• Enhanced Durability: Robust bellows construction maintains setpoint accuracy despite mechanical vibrations or pressure pulsations.
• Versatile Application: Suitable for a wide range of media including air, fresh water, and neutral gases in industrial control systems.
• Field-Adjustable: Features clear scale indicators for both range and differential settings, allowing for quick on-site calibration.
• Safe Electrical Interfacing: The SPDT contact system ensures reliable switching for both normally open and normally closed circuits.
• Compact Design: Small footprint facilitates easy installation in cluttered mechanical rooms or inside OEM control panels.

What is the maximum working pressure for the KPI35?
The Danfoss KPI35 is rated for a maximum working pressure (MWP) of 18 bar (261 psi), providing a significant safety margin for standard low-pressure hydronic and pneumatic systems.

Can this pressure control be used with steam?
While the KPI35 is highly versatile, it is primarily intended for air and water applications. For high-temperature steam applications, utilize a siphon to protect the internal bellows from direct thermal damage.

Is the differential fixed or adjustable?
The Danfoss 060-121966 features a fully adjustable differential, providing the flexibility needed to match specific system requirements and prevent unnecessary cycling.
