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.
