Danfoss Pilot Valves for Pilot Operated Servo Valves Data Sheet
Summary
These precision pilot valves are essential components for controlling large-scale servo valves in complex refrigeration systems. The manual provides comprehensive technical data on various valve types, including constant-pressure, differential-pressure, solenoid, and high-pressure models. Applicable to common non-flammable refrigerants, such as R717, this system ensures highly accurate pressure control regardless of the main valve size. Users can achieve advanced operational functions by connecting multiple valves in series or parallel, maximizing efficiency and reliability in HVAC/R applications.

Frequently Asked Questions
What gases and refrigerants are compatible with these pilot valves?
Compatible with all common non-flammable refrigerants, including R 717, and non-corrosive control gases/liquids (depending on the sealing material).
Where can I mount multiple pilot valve functions?
Multiple valves can be mounted in series or parallel on an ICS or PM main valve to achieve many functions.
Are these valves suitable for high-pressure applications?
Yes, there are high-pressure versions available (HP) and they are designed for various pressures, up to 7 bar g in some models.
What is required for connecting pilot lines?
Pilots can be connected directly into a main valve or via an external pilot line using a CVH housing.
