WebMar 3, 2014 · An EPIV Is a Belimo Electronic Pressure Independent Valve, a valve that continuously modulates in order to provide the correct water flow rate by electronically monitoring the actual water flow rate through the valve and adjusting its position accordingly. It has no mechanical pressure independence cartridge because it does not … Pressure independent control valves will often be abbreviated to the letters PICV. This is a type of valve found in Hydronic systems, meaning water based, which provide heating and cooling in buildings. These valves are basically a number of different valves conveniently combined into one unit. This saves … See more There are many variations of this valve. As you can see, their design changes as the size of the valve increases but their operating principle is almost the same.Let’s look at a smaller version to understand how it … See more So where do we use PICV’s? Well as briefly mentioned earlier, we use PICV’s in hydronic heating and cooling systems. These are found for … See more First let’s look at the control valve. The control valve acts like a normal valve. It has a cone which moves up and down to decrease or increase … See more In a hydronic heating or cooling system, we have pumps which boost the pressure and circulate the water. As we saw, some systems have pumps which vary their speed to change the … See more
WebApr 9, 2024 · As stated in the description of the PICV working principle, the use of PICVs limits the maximum flow at part-load conditions and thus avoids the mentioned increase of direct energy demand ... WebJul 10, 2024 · They are used to measure the differential pressure across the valve to ensure it is in excess of the minimum required for it to operate as a pressure independent control valve. How is a 2-Port PICV different to a 2-Port control valve? A PICV combines 3 valve functions in one housing: 1. Automatic balancing, 2. Differential pressure control, 3.
