ICS1-50A/ICS3-65D pressure regulating valve produced by Danfoss product details

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. ICS valves can be used on the high and lowpressure 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

• Designed for industrial refrigeration  applications for a maximum working pressure  of 52 bar g/754 psi g. • Applicable to HCFC, HFC, R717 (Ammonia) and  R744 (CO2). • Direct coupled connections. • Connection types include butt weld, socket  weld, solder and threaded connections.  • Low temperature steel body. • Low weight and compact design. • 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. • Maintenance spare part kit available for  ICS 100-150. • Modular Concept: – Each valve body is available with several  different connection types and sizes. – Valve overhaul on ICS 25-80 is done by  replacing the function module. – Possible to convert ICS pilot-operated  servo valve to ICM motor operated valve.

• Manual opening. • 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 directly into the ICS valve,  thus eliminating the need for solder/weld  connections or external pilot lines.  • Pressure gauge connection port to measure  valve inlet pressure. • The top cover can be rotated into any possible  position without affecting the operation of the  valve. • To get an updated list of certification on the  products please contact your local Danfoss  Sales Company.
