Product specification
Small pressure loss due to flow-enhancing housing
Corrosion-resistant
Metal-free, therefore no media oxidation
Free of plasticizers, therefore physiologically indifferent
High impact toughness but risk of breakage at low temperatures
Good mechanical stability
Very good dielectrical properties
Good chemical resistance
Hardly inflammable

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.
