ICS
ICS pilot-operated servo valves belong to the ICV (Industrial Control Valve) family.The valve comprises three main components: valve body, function module and top cover.
ICS pilot-operated servo valves are pilot operated valves for regulating pressure, temperature and ON/OFF function in refrigeration systems.
ICS valves are designed for low and high-pressure refrigerants.The small sizes are designed for MWP of 65 bar, while large sizes have MWP of 52 bar.
ICS valves can be used on the high and low-pressure sides, in wet and dry suction lines and in liquid lines without phase change (i.e. where no expansion takes place in the valve).
The function of ICS valves is dependent on the pilot pressure applied from either a pilot valve or external pilot pressure source.
ICS 1 pilot has one pilot pressure connection and ICS 3 pilot has three pilot pressure connections.
Features and benefits
- Designed for industrial refrigeration applications for a maximum working pressure (MWP) of:
- Direct coupled connections. Connection types include butt weld, socket weld, solder and threaded connections
- Lightweight, compact steel body designed for low temperatures
- V-port regulating cone ensures optimum regulating accuracy particularly at part load
- Function module has a QPQ surface treated insert and a steel piston ring ensuring precise control accuracy
- ICV 4 in., 5 in. and 6 in. ANSI with NPT threaded pressure outlet in the outlet of the valve
- Replaceable Teflon valve seat for ICS 25-80 and Maintenance spare part kit available for ICS 100-150
- Modular Concept
- The ICS valve is a multifunction valve where several pilot valves can be mounted into the pilot ports
- The standard range of pilot valves can be used on all sizes of ICS valves. Pilot valves can be either screwed directlyinto the ICS valve, thus eliminating the need for solder/weld connections or external pilot lines
Pilot valves for ICS Flexline™
As market trends moves in the direction of higher pressure Danfoss introduces a new line of pilot valves. The new pilots cover all regulation, types, and ranges needed in ammonia and CO₂ applications. Full backwards compatibility ensures smooth transition. The new line of pilots for ICS valves reduces the number of variants from eight to only four simplifying ordering, inventory management and storage.
The high quality Pilots are based on the patented Danfoss membrane package and to ensure long durability the CVC, CVP and CVPP are surface treated and the CVE made of stainless steel.
Product Highlights
- Single platform for all specifications
- Easy ordering
- Simple inventory management
- Backwards compatibility
- Less shelf space required (store & stock)
ICS, pilot operated servo valve
ICS is a compact, pilot operated servo valve. An ICS valve comprises three main components: a valve body, a function module and a top cover. The function of the ICS valve is defined by the pilot valves connected.
