The new STEVI AS Y-pattern process
valve from ARI-Armaturen delivers
power and tight shut-off for up to
1,000,000 strokes. The self-adjusting
stem sealing system, comprising
spring loaded PTFE-V-ring unit and
burnished stem with double bearing,
ensures a tight seal.Water hammer is
reduced to a minimum due to the
damped closing function.

The valve is said to deliver
exceptional economy in the form of
energy savings. The flow-optimised
Y-pattern body design facilitates
large strokes and good flow
capacities, and a 31% energy saving
can be achieved.

Reliability is said to be assured even
at high differential pressures due to
the use of three different spring
strengths as standard.
