Pressure & Level Regulation

Danfoss ICS Servo-Operated Main Valves

Danfoss Authorized Distributor (China) Wenzhou Phonetoo is an authorized Danfoss distributor in China — listed in the official Danfoss dealer directory.

Danfoss ICS Servo-Operated Main Valves for industrial refrigeration systems, supplied by Wenzhou Phonetoo Electromechanical Co., Ltd. — an authorized Danfoss distributor in China. Contact us for availability, pricing and delivery time.

ICS pilot-operated servo valves are the modular heart of Danfoss industrial refrigeration control. One main valve body accepts a wide range of pilots — solenoid, pressure-regulating, temperature or motorized — to build exactly the function the system needs.

Full specifications available on request. Tell us your refrigerant, operating conditions and required capacity or connection sizes in the RFQ form and we will confirm the exact Danfoss model and code number for your application.

Code numbers

Ordering codes for Danfoss ICS pilot-operated servo valves: valve bodies, function modules and top covers from the parts programme, complete factory assembled valves, ICSX parts and ICV PM valve housings. Confirm the exact type and code number in your RFQ and we will quote it.

Frequently asked questions

What is the Danfoss ICS valve?

The ICS is a pilot-operated servo main valve for industrial refrigeration. Fitted with one or more pilot valves, it controls refrigerant flow by modulation or on/off — used for pressure, temperature and level control duties.

What pressure is the ICS 50 rated for?

The ICS 50 belongs to the small-size range (DN 25–80), rated for a maximum working pressure of 65 bar. Large sizes DN 100–150 are rated 52 bar.

Which pipelines can the ICS be installed in?

The ICS can be applied to any pipeline in the refrigeration system, including liquid lines, suction lines and hot gas lines — selection depends on the pilot valve configuration.

Which refrigerants is the ICS suitable for?

The ICS is applicable to HCFC, HFC, R717 (ammonia) and R744 (CO₂).

How is the ICS controlled?

The main valve is controlled by pilot valve(s): depending on the pilots fitted, it provides modulating control or on/off control in line with the control signal.

What is the difference between ICS and a direct solenoid valve like the EVRA?

The EVRA is a self-contained solenoid valve for simple on/off duty. The ICS is a servo main valve whose function is defined by its pilot valves, so one valve body can serve as a solenoid valve, regulating valve, check valve function and more.

Is this a genuine Danfoss product? How long is delivery?

Yes. We are an authorized Danfoss industrial refrigeration distributor in China, listed in Danfoss China’s official authorized dealer directory. All valves are brand-new, genuine stock with valid warranty. We ship from China; express delivery takes about 1–2 weeks to most destinations worldwide.

Can you help select the right ICS configuration?

Yes — tell us the application (e.g. liquid line solenoid, hot gas defrost, suction pressure regulation), refrigerant, pipe size and pressure rating, and we will propose the valve plus pilot valve combination.
