High performance

ALFA VALVES SERIES S96-S97-S98

Alfa Valves is a producer of soft seat, metal seat and fire-safe seat HIGH PERFORMANCE butterfly valves.

The valves are manufactured according ISO 9001 Quality Assurance and is designed and tested to meet or

exceed the most general industrial standards and are a result of a long time experience in the design and

manufacturing of valves.

Wafer-Lug and Double flange design for bi-directional dead-end

service acc PN10/16 and Ansi 150 ratings.

The double eccentric offset assure a low operation torque and

easy replaceable liner system without bolts. The S96, S97 and

S98 valves have a Disc stopper to prevent Disc over travel.

The Disc design gives a maximum flow and minimum resistance

and creates max, Cv values. The outside diameter of the Disc

is polished for max. valve life time.

The one piece stem design gives higher strengh and lower

valve torque.

The V-Packing are designed to give max. resistance to pres-

sure both low and high pressures. Special packings like Grafoil

are available for high temperature applications and are standard

on our fire safe design valves and on our metal to metal valves.

All valves are tested according Internaltional standards like

API 598-MSS SP 61-BS 6755 and Ansi B 16.104.

SOFT SEATElasticityofthePFTEorPTFE(R)seatandfluidpressure assures perfect “bubbletight”sealing.

METAL SEATThis version offers very high sealing capability with an unusually low leakage rate.

FIRE SAFE SEATAfterafirewhenthePTFEseat has burned away, the supplementary metal sealing seat activates auto-matically and prevent from excessive flop.
