FOCUS ON PUMPS AND VALVES
At present, control valves are increasingly
becoming the focus of a wide variety of ap-
plications. In order to provide the customer
with a simple selection guide, GEMÜ has
now summarised all the relevant compo-
nents of a control system under the term
Process Control System, or PCS.
The PCS type combines the standard
GEMÜ control valves with mounting kit,
piping system and positioner. In this way,
the customer has the option of ordering
the appropriate control system and all the
necessary components quickly and without
error. Each nominal size has two regulat-
ing cones (linear and equal-percentage) to
choose from as standard.
The operators for the GEMÜ 554 (plas-
tic), GEMÜ 514 (aluminium) and GEMÜ 550
(stainless steel) series are available in the
form of actuators. GEMÜ 1434, 1435 and
1436 have been integrated into the PCS as
controllers. The standard versions of each
controller are regarded as basic versions.
The GEMÜ 514, 530, 532, 534, 550 and
554 series contain the nominal size range
of DN 15 to DN 50. The GEMÜ 536 globe
valve covers the nominal size range of DN
65 to DN 150.
GEMÜ is one of the world’s leading
manufacturers of valves, measurement
and control systems. Over the course of
more than 50 years, this globally focused,
independent family owned enterprise has
established itself in important industrial
sectors thanks to its innovative products
and customised solutions for process media
control.
Manufacturing is carried out at six manu-
facturing sites in Germany, Switzerland,
China, Brazil, France and the USA. A broad
based modular system and adapted auto-
mation components mean that individu-
alised standard products and customised
solutions can be combined to make over
400 000 product versions.
