Danfoss Randall 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.
These valves, based on traditional designs but
improved by on-going product development,
are second to none in terms of robustness,
dependability and operating efficiency. Higherthan-
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, and yet there is no price premium for the
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.
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 caters for virtually all needs, ie. 2-
port, 3-port diverter or mid-position, metric sizes
15mm, 22mm and 28mm with copper
compression fittings and imperial sizes 1/2", 3/4"
and 1" BSP threaded.
