Danfoss servo control of the level main valve（ICS25/40/50 / ICS3-65）Product introduction
Danfoss industrial ammonia refrigeration system level regulator ICS series pneumatic solenoid valve
Summary: ICS servo main valve is one of the members of the family of a new generation of industrial control valves ICV. ICV products - ICS - industrial control servo valve - ICM - industrial control of electric valve ICS servo main valve has introduced the concept of modular design, consists of three modules: the valve body, function modules and the valve cover. ICS is controlled by the pilot valve of the main valve, pressure level of the refrigeration system and can be used in all kinds of pressure, temperature and the switch control system. ICS can be used in the refrigeration system of high/low voltage side, wet/dry way back to the trachea, and no phase change of liquid pipeline (for example, there is no throttling, the expansion of the piping) ICS valve function depends on the pilot valve or an external pressure source. ICS1 has a pilot valve interface, three pilot valve ICS3 interface. Pilot valve can be installed directly on the ICS valve, can also be mounted on the external pressure on the tube. A ICS valve should be installed at the same time a few pilot valve can achieve a variety of different regulating function. ICS valve bonnet can connect pressure gauge, to monitor the body in setting set-up or pilot valve inlet pressure. ICS valve manual adjustment screw on the end cover can manually open the main valve.
Features: s refrigeration applications for industrial design, the maximum working pressure 52 bar / 754 psi, g
S ICS 25-150: suitable for common refrigerants, including ammonia, carbon dioxide, and non-corrosive gas, liquid
S welding interface directly
S connection mode including butt welding, socket welding, brazing and threaded connection resistance to low temperature carbon steel valve body
S design is compact, light in weight
S optimization design with v-shaped LiuKou valve core, to ensure that provide the best adjustment ability in partial load
S function module for the QPQ surface treatment (black), steel piston ring valve has precise adjustment accuracy
S the idea of modular design
- every body has a variety of different welding methods and size are optional
- only replace function module to complete update of the valve
- without having to change body, it can realize the ICS between servo valve and the ICM electric valve to replace each other
S manual open function
S ICS is a multifunctional valves, several pilot valve can be installed at the same time
S all pilot valve adopts screw connection, can be directly spiral twist on ICS main valve of all sizes, don't need to be welded or separate conduit connections
S ICS on the main valve can connect pressure gauge, so it can measure the inlet pressure of the valve body
S ICS main valve cover can be installed on the valve body from any direction without affecting the function of the valve
Technical parameters: ICS valve through the pilot valve open servo valve, it needs to open is a very small pressure difference. When the differential pressure at the ends of the valve body is 0 bar / 0 p s I, I C s valve will remain closed. When the valve differential pressure is 0.2 bar / 3 psi or above, ICS will fully open valve. When the valve pressure difference in 0.07 psi to 0.2 bar bar / 1/3 psi, ICS valve opening will open in proportion according to pressure difference.
ICS can main valve and 1 to 3 pilot valve interface configuration used together. Connection mode: ICS valve shall be connected by a variety of ways to install D: butt welding, DIN (2448).
S A: butt welding, ANSI (36.10 B)
S J: butt welding, JIS (S 602 B)
S SOC: socket welding, ANSI (16.11 B)
S SD: brazing, DIN (2856).
S SA: brazing, ANSI (16.22 B)
S FPT: FPT pipe thread (ANSI/ASME B 1.20.1)
Two of the three pressure pilot valve interface (S1 and S2 interface) as the series connection and the third interface (P) and S1 and S2 interface in parallel. This provides different pilot valve connection configuration, so it can provide a variety of different control function.
S technical data
Suitable for all kinds of flammable refrigerants not include ammonia, carbon dioxide and non-corrosive gas/liquid medium. Not recommended in combustible hydrocarbon occasions, if you need more detailed information, please contact with guangzhou, zhuo trade co., LTD.
S temperature range: - + 60 ℃ / 120 ℃ (76 ℉ / + 248 ℉)
S surface protection ICS25-150: the outer surface of galvanized processing, can have
Effectively prevent corrosion pressure maximum working pressure range: 52 bar
S the main valve fully open differential pressure: minimum of 0.2 bar (3 psi);
- the largest open differential pressure (MOPD), (only used for electromagnetic valve from time to tome
Meaning), under normal working conditions
- 10 W a.c, up to 21 bar (305 psi)
