More variants on show at Achema

Valves for any situation

At Achema 2018, the ARI is expanding its valve range with further variations Picture: ARI
ARI’s extensive portfolio of valves for the process industry comprises 20,000 products in more than 200,000 variants. At Achema 2018, the valve manufacturer is expanding this range with further variations. A brief summary of the most important new additions is provided below.

The butt weld end version of Zetrix, the metallic sealing, triple offset premium process valve, is a new addition to the ARI range. It is available in sizes DN 80 to DN 600 for PN 6 to PN 40 (class 150/300). Also new from ARI: the fully lugged, wafer flange version is now additionally offered in DN 80 to 600 for PN 63/100 (class 600). For several years, this sophisticated range of process valves with metallic sealing and a self-aligning sealing ring has been rounded off with a double flanged version. Zetrix valves combine extreme reliability and durability. All models have a stellited seat and are fire-safe tested with bidirectional gas-tight shut-off and zero leakage according to EN 12266-1 and API 598.

For critical applications

Everything is possible with the new Stevi Vario – the variable, compact control valve which impresses with its wide diversity. In particular, the changeable, variable trim and the different actuator designs provide users with incredible flexibility. The Stevi Pro high-performance control valve for professional control, especially in critical applications, further extends the range. The stainless steel variant can now also be supplied by ARI with a stainless steel bellows. With its optimised characteristic quality, high precision and performance are guaranteed. And thanks to the blow-out proof stem and shaft guided plug – as well as a two-ply bellows seal on request – the Stevi Pro is safe even in harsh industrial environments.

More bellows valves

The ARI bellows valve range, already very versatile, has likewise been expanded. For the first time, ARI can now offer the process industry Faba Supra MD bellows valves for PN 63 to PN 160. When fitted with a balancing plug, these valves are even safer
to use (optional from DN 65). They are reliably tight, even at high pressures, owing to the bellows seal, serrated seal and stellited marginal plug (ideal hardness gradient: Stellite 6/Stellite 21).

Focus on safety

The safety valves product group has been extended yet again. In future, ARI customers can optionally order any Safe valve in stainless steel – up to size DN 250 including a stainless steel bellows. The bellows not only provides backpressure compensation; it also seals and protects the spring chamber and the guides. The two-fold safety due to the separate balanced piston, which acts redundantly with the bellows and is supplied as a standard feature, is a another decisive advantage. Increased safety is possible on request in the form of two ARI combinations: Safe Combi-C (change-over valves) and Safe Combi-R (rupture discs).
