General Information
Break-proof, tight-closing check valves made of PVC-U or PP and PVDF resp. The liquid-tightly enclosed metal core of the valve piston guarantees a complete shut-off already at low working pressures. The valve is distinguished by freedom from maintenance and simplest design.
The sizes DN 15 to DN 50 can be retrofitted with a FEP-coated shutting spring providing a safe closing function at horizontal or vertical installation with overhead valve body.
