ARI-Armaturen’s new STEVI®AS Y-pattern process valve offers shut-off for up to 1,000,000 strokes. The self-adjusting stem sealing system, composed of a spring loaded PTFE-V-ring unit and a burnished stem with double bearing, ensures a tight seal on closing with zero leakage.
Water hammer is reduced to a minimum due to the damped closing function. Suitable for a wide range of applications in processing technology, mechanical engineering and plant construction, the new STEVI®AS further extends the comprehensive range of specialist valves available from ARI-Armaturen.
The STEVI®AS is highly versatile due to the bidirectional approach flow to the plug, and flexibility is further extended with a range of optional components including travel limiter, limit switch (inductive or mechanical), handwheel for emergency operation, 3/2-way solenoid valve or NAMUR adapter plate.
