ARI-ZESA® Wafer Type Butterfly Valve DN25/32 PN16
Reliable flow management with compact design and excellent sealing.
ARI-ZESA® Wafer Type Butterfly Valve is a critical component for flow control in industrial piping systems. In particular, its DN25/32 connection size and PN16 pressure class make it reliable for medium-sized lines. Moreover, the ductile iron body and 1.4581 stainless steel disc provide excellent sealing in both directions. Furthermore, it fully complies with DVGW and VP646 standards, so it is suitable for drinking water networks.
This valve features a stainless steel stem and an EPDM seal system. As a result, it offers high corrosion resistance and can operate for over 20 years without maintenance. In addition, its zeta value of 0.27 reduces energy loss, preventing unnecessary load on pumps. Consequently, it lowers operating costs and maximizes system efficiency. The technical specifications include Model Information: ARI-ZESA®, Nominal Diameter (DN): DN25/32 (1 inch / 1.25 inch), Pressure Class (PN): PN16 (16 Bar nominal), Disc Material: 1.4581 stainless steel (Duplex), Seal System: EPDM (Ethylene Propylene Diene Monomer), Standard Compliance: DVGW, VP646, EN 12516-1, Operating Temperature: -10°C to +80°C, Zeta Value: 0.27 (low energy loss).
ARI-ZESA® Wafer Type Butterfly Valve — Technical Specifications
This valve serves a wide range of applications, from municipal water distribution networks to heat exchangers. In particular, it performs successfully in industrial process flow control and integration into automation panels. Moreover, its thermal insulation cover provides energy efficiency fully compliant with the German ENEV regulation. Furthermore, it delivers equally successful performance with manual operation or electric actuators.
