Ball valves
High-Performance metallic sealing gastight ball valves for severe service applications
Designed to individual customer requirements, Hartmann ball valves guarantee the highest levels of safety and availability – even under extreme operating conditions. As a reliable shut-off valve, they resist aggressive media, extreme pressures and temperatures or frequent actuating operations. The metal-to-metal sealing between ball and seat rings with high quality hardfacing provides an especially long service life and minimises maintenance requirements.
The ball valves are equipped with hand lever or gearbox for manual operation. Automatic operation by means of electric, pneumatic or hydraulic actuators. Configuration variants e.g. rapid close, fail-safe-open, fail-safe close and high cycle with ≥200,000 actuations per year. We develop tailor made solutions for special process requirements.

Shut-off ball valves with trunnion mounted ball (type AST) or floating ball (type ASF)
Pigging valves also as replacement for scraper launching systems for measurements, cleaning and separation of media
Ball valves with integrated components such as strainer or non-return valve
Twin ball valves with multiple barriers in pressure direction and cavity pressure bleed off for increased safety requirements
Multi-way ball valves for diversion and changeover units
Heating jacket ball valves for media requiring an increased temperature (e.g. sulphur)
Flow Control ball valves with linear or equal percentage flow characteristic
Drill string ball valves such as Kelly valves and IBOP
