H Series Motorised Valves
Rotary-Shoe and Paddle Types
Features
These valves are developed to provide robustness,
dependability and operating efficiency. Designed
to withstand higher-than-usual test pressures,
support bearings at both top and bottom
of the shoe and paddle spindles and tough
polycarbonate actuator covers are some of the
features which ensure this added quality.
H Series valves are normally purchased as separate
valve bodies and actuators, but are available as sets
for some of the more popular combinations, see
Product Selection Guide for details. Actuators are
fitted to the valve bodies on site for convenience
of installation and serviceability.
The H Series Motorised Valves, working in
conjunction with time controls and thermostats,
are used in domestic and commercial central
heating, hot water and chilled water systems to
control the flow of water in the system.
They are designed and built for long term operation
under arduous conditions of high temperatures
and rapid pressure fluctuations.
Available as either rotary-shoe or paddle types,
H Series valves offer the specifier and installer
whatever he decides is appropriate for the job.
The range includes 2-port, 3-port diverter or midposition, metric sizes 15mm, 22mm and 28mm
with copper compression fittings and imperial
sizes 3/4” and 1” BSP threaded.
• Suitable for heating and cooling applications
• Proven reliability
• Long working life
• Actuators and valve bodies supplied separately
for convenience
• Easy installation and wiring
• Industry-standard fittings and wiring colours
• Robust construction

Sizing The pressure drop across an H Series valve can be
determined from this Kv diagram.
The chart, which shows the Kv values of all H Series
valves as diagonal lines, can be used to determine
pressure drop when the flow rate is known (m3/h).
It can also be used to read off pressure drop values
when the heating load (kW) is known.
A vertical axis, scaled in kW for systems working at
temperature differences of either 11°C or 20°C, is
included in the chart.
Alternatively, pressure drop values can be
calculated using the formula:
∆P = Q
Kv
2
( )
Where:
Q = Flow rate (m3/h)
Kv = Co-efficient of Flow (m3/h)
∆P = Pressure Drop across the valve (bar)
Kv values of each valve type and size are shown in
the table opposite.
By following a vertical line downwards from this
point, a pressure drop of 0.11 bar can be read off
the horizontal axis at the base of the chart.
2) To determine the pressure drop across a 22mm.
2-port paddle valve (Kv = 5.8), for a 20 kW heating
load in a system working at an 11°C temperature
difference, follow the horizontal line from the 20
kW point on the appropriate right-hand vertical
axis until it crosses the diagonal 5.8 Kv line.
By following a vertical line downwards from this
point, a pressure drop of 0.072 bar can be read
off the horizontal axis at the base of the chart.
Examples of chart use:
1) To determine the pressure drop across a 22mm.
3-port paddle valve (Kv = 6.1), at a flow rate of
2.0 m3/h, follow the horizontal line from the 2.0
m3/h point on the left-hand vertical axis until it
crosses the diagonal 6.1 Kv line.
