Control Ball Valve Type W

Control Ball Valve Type W

The ARTES control ball valves W is a control valve that has been specially designed for pressure and quantity regulation. The design makes it possible to securely shut off the medium in addition to its regulating function. The valve has been designed for use with liquid and gaseous media, for example water and steam.

Media

Steam, hot gases

Typical places of use

• Feed water control valve
• Start-up control valve
• Fill level regulation (feed water container, drums)

Basic technical data

• Nominal pipe size: DN25 … DN800 (1″ … 32″)
• Nominal pressure class: PN16 … PN400 (ANSI class 300 … 2500)
• Temperature: up to 600 °C

Main advantages

• The purely metal seal of ball and seat ring ensures the seal in the ball passage
• The valve is permanently leak-tight to the outside
• The straight flow-through of the valve permits a per manent pressure loss of 0.2 bar whilst guaranteeing constant control performance
• Fast adaptation of the valve to changes in operational requirements by replacing the control discs
• Controlled multi-stage pressure relief is possible
• highly resistant to wear due to its tungsten carbide coating
• Simple installation and removal, also for welded version
