2- or 3-part screwed control ball valve with one or two integrated control discs. Trunnion mounted ball and protected metal-to-metal seat design. Double Block and Bleed (DBB) Double Piston Effect (DPE) design possible. Coatings and surface treatment for medium-contacted parts available.
The control ball valve with its design variants artec-N, artec-P and VariTEC is a control valve for an extensive range of applications. It is used to control a wide variety of processes in power stations, chemical plants, oil and gas industry, steel industry and others. The control ball valve is characterized by excellent wear resistance, high control quality, robust design, and lowest permanent pressure loss. It is particularly qualified for challenging control tasks with high pressure drops, cavitation, and erosion conditions. The straight flow through and the rectifying effect of the control disc effectively protects the body parts and the pipeline from wear.

Features
- High wear resistance due to design principle: ball/seat ring overlap, trunnion-mounted ball, control disc arrangement and design, WCB-coated internal parts
- Multi-stage pressure reduction possible
- High control accuracy
- Individually adapted control disc design
- Vibration-free and low noise
- Turn-Down Ratio max 200:1
- Self-locking
The control ball valve is also available in EN Standard (S.221/1-001). According to specific requirements, the control ball valve can also be designed differently from the below listed options.
