Control Valves


HORA’s product range covers a multiple of applications in Building Automation, Industry and Gas storage/distribution today.
It includes control valves, butterfly valves, mixing valves, and electric linear and quarter-turn actuators. HORA can supply a range of products which is probably the most extensive offered by any company in Europe. HORA is a partner to all the leading measuring and control firms, system suppliers and system houses.

Thanks to HORA’s quality, medium at pressures up to PN 40 and temperatures up to 350 °C can be safely controlled – and with diameters up to DN500. Our team of sales and technical experts is able to develop process-optimised solutions.

HORA’s actuators with micro-controller can be adjusted in situ to meet all kinds of control and regulation requirements. Through automatic self-calibration and variable adjustment, they are suitable for universal application.

HORA produces control valves in over 100,000 variations including:

   1/2″(DN15) to 20″(DN500)plug & seat valves
  Selection of Kvs values per size
  Linear or Equal% characteristics
  Extremely low leakage
  Pressures up to PN40 (40Bar)
  Valve bodies in cast iron, cast steel, SG iron and stainless steel
  Balanced plug options for greater close off pressures.
  Actuators for 24Vac, 230Vac, 0…10Vdc, 4…20mA and pneumatic operation.
  Options for IP65 housing and supplied assembled, stroked and tagged.
  Butterfly valve range up to 16″ (400mm)

HORA have a complete range of Actuators to achieve close off pressures for all applications.

If the linear actuator is blocked manually, the linear actuator will briefly move back and then retry to reach the required position. If this is still unsuccessful after a total of 7 attempts the linear actuator will be turned off in order to prevent damage to the linear actuator and the control element.

The HORA iPhone App valveRuler

An old slide rule in digital format

The good old slide rule was a highly desired tool for planners and technicians over the course of 20 years. But now it is ready to retire: The modern iPhone App valveRuler is ready to replace it.

Simple designs of valves for water and saturated steam applications can be immediately undertaken at the flick of a wrist.

  • Nominal size (DN)
  • Flow volume in m3/h
  • Mass flow in t/h
  • Flow coefficient (kv-/kvs value)
  • Pressure drop delta p

All that you need is your iPhone and some operating parameters. The intuitive user interface delivers a quick and easy result. Reference values for flow speeds and instructions on critical pressure differences support you in the correct selection of nominal sizes and kv-/kvs value. The DIN EN 60 534 based result can be sent by e-mail – to colleagues or even to us, to get an offer or to obtain further data.
