ICS Flexline™ servo operated valves

Versatile functionality, flexible operation

Part of the ICV Flexline™ valve family, ICS pilot-operated servo valves comprise three main components: valve body, function module, and top cover. Designed for low- and high-pressure refrigerants, ICS valves can be used to regulate pressure, temperature, and on/off functions in refrigeration systems. Incredibly versatile, 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.

Thanks to their low weight and compact design, ICS valves are quick and easy to handle, install, and service. Designed and tested to withstand a maximum working pressure of 65 bar (943 psi) in a media temperature range of −76°F to 248°F, ICS valves are suitable for CO₂, ammonia, and other high-pressure refrigerants.

The ICS's special regulating cone V-port design allows the temperature set-point to be adjusted to a higher level, and a better COP, leading to energy savings.

ICS's modular design enables a high degree of flexibility to create a valve that meets system requirements. The common valve body for ICS is available in several different connection sizes. Different function modules in the ICS series offer a wide range of capacities and functions which can be installed in each valve body. The valves have direct weld connections allowing for high pressure and a tighter design compared to traditional flanged valves.
