VA Valve Balls
Available valve balls materials for Verderair VA series pumps
Acetal
Wide range of solvents resistant and whitstands extreme fatigue. Good level of abrasion resistance. Not for use with acids or bases.
PTFE
Widest chemical resistant. Extreme corrosion resistance but limited abrasion resistance.
BUNA N
Good for water, petroleum based and hydrocarbon fluids. Not for use with strong solvents or chemicals.
Geolast
Good abrasion resistance. Similar chemical compatibility as Buna N.
Hytrel (TPE)
Often used as substitute for Buna N
Santoprene
Good abrasion and chemical resistance. Not for use with solvents or hydrocarbons. Often substitute for EPDM.
Fluorelastomers (Viton)
High level of corrosion resistance with acids. Good resistance for steam and unleaded fuels.
Polychloroprene
Very soft rubber. Good for abrasion. Limited resistant for corrosion.
Polychloroprene weighted
Polychloroprene with metal insert. For use with high viscous and high density fluids
Stainless Steel 316
High level of corrosion and abrasion resistance. Can handle halogenated carbons.
Hardened steel
Moderate chemical resistance. Good abrasion resistance.
Available valve balls materials for Verderair Almatec series
Stainless Steel 316
High level of corrosion and abrasion resistance. Can handle halogenated carbons.
BUNA N
Good for water, petroleum based and hydrocarbon fluids. Not for use with strong solvents or chemicals.
EPDM
Good general chemical resistant. Not for use with hydrocarbon fluids!
PTFE
Chemical inert. Can be used in almost all chemical applications. Limited abrasion resistant.
Cylinder valve PTFE
Chemical inert. Can be used in almost all chemical applications. Better suction capabilities then valve balls.
