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.
