Main advantages

• It realises the function of 2 control valves, reducing installation costs and requiring only one actuator

• Defined leakage in the passage through a defined gap between the rotary segment and housing, thus ensuring a minimum flow through the closed connection

• No vibration fractures, after positioning, the stem is free of forces and torques

• Straight flow-through permits a permanent pressure loss < 0.1 bar whilst guaranteeing constant control performance

• Optimal piping due to arrangement of the pipe axes in one plane

The ARTES desuperheater is a control valve that regulates the temperature of steam by spraying cooling water.

Typical places of use of a desuperheater

• in steam generators of power plants and other industrial systems

• special applications using other media have also been realised

Basic technical data

• Nominal pipe size: from DN150 (6”)

• Nominal pressure class: PN400 (ANSI class 2500)

• Temperature: up to 620°C

Main advantages of the ARTES desuperheater

• The cooling water is always injected into the centre of the pipe, regardless of the quantity

• The perfect combination of rotary movement, nozzle design and nozzle controlling ensures reliable and precise cooling in all load cases

• The use of high-grade materials helps to prevent vibration fractures in the functional components and ensures reliable operation without interruptions

• With its large rangeability, ARTES desuperheaters offer outstanding quality of control. The control performance is continuous across the entire controlling range

• The valve is permanently leak-tight to the outside

• The item can be actuated by means of electric, pneumatic or hydraulic actuators

Steam-atomising desuperheaters are cooling systems for controlling the temperatures of steam and hot gases. Their task is to reduce temperatures in pipelines, or to provide process steam with a precisely defined temperature.

Typical places of use

• Steam cooling, production of saturated steam

Basic technical data

• Nominal pipe size (steam pipe): from DN150 or 6”

• Nominal pressure class:
  up to PN400 (ANSI-class 2500)

• Temperature: up to 600 °C

Main advantages

• Good heat exchange and low vaporisation time

• Excellent control performance at partial load

• Large rangeability possible

• Cooling to saturated steam temperature possible

• Low thermoshock hazard

• Short distance to temperature measurement

• Better mixing due to turbulence of the motive steam

• Good vaporisation even at low vapour pressures
