How to Find Valve Pressure Drop
The pressure drop in psi (kPa), equivalent ft (m) of pipe, or feet
of water (kPa) may be calculated from Figs. 3 through 8 as
follows:
1. Calculate the flow rate to heat the zone.
2. Determine the Cv (kV) rating of the motorized valve.
3. Select the graph corresponding to the Cv (kV) rating
(Fig. 3 through 8).
4. Determine the pressure drop across the valve using the
following procedures for calculating pressure drop.
PRESSURE DROP IN PSI (KPA)
1. Locate the flow rate at the bottom of the graph.
2. Draw a line upward from the flow rate to the intersection
of the curve.
3. Draw a line from the intersection to the left edge of the
graph to determine the pressure drop in psi (kPa).
PRESSURE DROP IN EQUIVALENT FT (M) OF PIPE
NOTE: Both 1/2 and 3/4 in. pipe conversion scales are avail-
able for this determination.
1. Locate the flow rate at the bottom of the graph.
2. Draw a line vertically to the top of the graph. Determine
the pressure drop for either the 1/2 or 3/4 in. pipe.
PRESSURE DROP IN FT OF WATER (KPA)
1. Locate the flow rate at the bottom of the graph.
2. Draw a line upward from the flow rate to the intersection
of the curve.
3. Draw a line from the intersection to the right edge of the
graph to determine pressure drop in ft of water (kPa).
