Product Description:

The Danfoss 027H8200 is very strong and protects against rust, making it great for usage in tough conditions. This valve is made of low-temperature steel and has a zinc-chromated surface. It can handle a maximum working pressure of 52 bar g (754 psi g) and can work in a broad variety of temperatures, from –76° F to +248° F (–60° C to +120° C).

Users may utilize the 027H8200 with a wide range of refrigerants, such as HCFC, HFC, R717 (ammonia), and R744 (CO₂). This makes it useful for both old and new refrigeration systems. Because it is small and light and has a direct-coupled connection mechanism, it is easy and quick to install. The V-port regulating cone is an important aspect of this valve. It makes sure that the regulating is as accurate as possible, especially when the load is low. Both of these parts help to make sure that the control precision is high and that the module lasts a long time.

The ICS main valve is controlled by a pilot, and the sort of pilot valves employed determines what it does. The main valve and the pilot valve(s) may work together to regulate the flow of refrigerant in either a modulated or an on/off way, depending on how the pilot is set up. The valve has a manual spindle that lets one open the valve plate by hand when one need to. For the function module to work properly, the pressure (p3) below the servo piston must be equal to the pressure (p4) at the valve outlet. This is made possible by a specified clearance. The opening degree is controlled by the p2 pressure on top of the servo piston, which must be equal to or greater than the outlet pressure (p4) for the valve to work properly.
