Pressure Dependent Valves 1)What type of valve would the customer like?Ball Valve (CCV, ZoneTight, Industrial), Globe Valve or Butterfly Valve 2)Calculating the CV.What is CV? CV = The amount of water flow (GPM) through a fully open valve with 1 psi pressure drop.Why is CV important?If CV is too high, that means the valve is oversized and this will result in sloppy control and inefficient system performance.If CV is too low, that could result in insufficient flow and starve the coil.
