Overview
The Georg Fischer Type 343 ball valve is a manually operated 2″ DN50 ANSI ball valve designed for industrial and commercial flow control applications. Built with CPVC (chlorinated polyvinyl chloride) housing and equipped with EPDM seals, this valve delivers reliable shut-off and flow regulation across hydraulic, pneumatic, pump, and plumbing systems. Swiss-engineered and manufactured to ISO standards, the Type 343 combines durability with chemical resistance for demanding environments.
Key Features
- Manual lever operation for intuitive open/close control
- CPVC housing material provides superior chemical resistance and temperature stability
- EPDM seals ensure reliable performance across wide fluid compatibility ranges
- 2″ ANSI threaded connection for standard industrial piping integration
- Compact, space-efficient design suitable for retrofit and new installations
- Swiss precision manufacturing meets international quality standards
