The ARI-EURO-WEDI from ARI-Armaturen is a soft-seated shut-off valve with throttle characteristic that releases or shuts off the volume flow in the system. ARI offers the EURO-WEDI in different versions. The flanged design is available in FTF-14 (short design) / FTF-1 (long design) and the threaded design in the length FTF-14 (short design). The material for all versions is grey cast iron (5.1301). The EURO-WEDI, flange connection, is available in pressure ranges PN 6 and 16, threded connection in pressure range PN 16. The nominal diameter are DN15-200 (flange connection), DN15-50 (1/2‘-2’) (threaded connection). The temperature range is from -10°C to +120°C (briefly up to +130°C).

The fully encapsulated EPDM cone has an almost linear flow characteristic (throttle characteristic). Thanks to the self-centring throttling plug (dual function of shutt-off and throttling). The EURO-WEDI is absolutely reliable in terms of tight shut-off (leakage rate A according to DIN EN 12266). Our patented elastic double seal (EDD), combined the stem sealing c/w a scraper. The scraper removes any deposits from the spindle surface and guarantees tightness to athmosphere. In addition the encased EPDM plug relieves the stem seal (back seat) in fully open position.

Thanks to the internal stroke limiter (lower installation height), the locking device, the non-rising handwheel and the position indicator as standard device, the EURO-WEDI achieves ideal handling, even in space limited assembling areas.

The durability of the valve is important for us. When used in cold water/air conditioning systems, the standard insulating cap with dew point barrier protects against condensation and prevents corrosion on the valve (corrosion protection). The standard anti-rotation device (double-guided plug) and the fine-thread stem (slow immersion of the plug towards the seat = gentle on the material) provides a long service life.

Energy efficiency is becoming increasingly important. The ARI-EURO-WEDI can be fully insulated according to the German Building Energy Law (GEG). Further energy and cost savings result from the favourable zeta values (<= 1.2).

Flow regulating valves ASTRA®

ASTRA®

Static flow regulating valve

• Material: grey cast iron (EN-JL1040)

• Non-rising handwheel with travel limiter and digital display (DN250-500 travel indicator)
• DN250-500 with V-port plug, seat-guided over the entire stroke
• Integrated pressure gauges as standard, located on the flanges.
• Optional pressure gauge extensions
• Insulating cap with dew point barrier

• Adjustable with the ARImetec-DX measuring device

ASTRA® D

Dynamic flow limiter – for automatic hydraulic balancing of heating, ventilation and air conditioning systems

• Nominal sizes: DN50-800
• Pressure ratings: PN16/25
• Temperature range: -10-110°C
• Material: ductile iron (EN-JS1030)
• Maximum energy savings by limiting the flow regardless of the differential pressure over the valve – thanks to integrated automatic inserts (avoidance of oversupply)
• Cost and energy savings thanks to easy-to-insulate wafer type with a compact overall length of 170mm of all nominal sizes.
• Reduction of operating costs and setting security through firmly defined limitation of the volume flow (no manual readjustment, no complicated installation since inserts are set in the factory)
• Complete insulation possible in accordance with the Gebäudeenergiegesetz - GEG
• Integrated pressure gauges as standard

ASTRA® DC

Pressure independent control valve

• Nominal sizes: DN50-150
• Pressure ratings: PN16/25
• Temperature range: 0-120°C
• Material: grey cast iron (EN-JL1040) / nodular iron (EN-JS1024)

• Consists of an adjustable volume flow controller, a differential pressure controller and a modulating control valve - for maximum energy efficiency under changing conditions (with electric actuator or handwheel)
• Perfect control of the system through fully modulating control with full valve authority and maximized ΔT - regardless of any fluctuations in the systems differential pressure
• Cost savings as no additional control valves are required in the system (reduction in the total number of valves due to the combined 3-in-1 design)

• Integrated pressure gauges as standard

ZESA/GESA®

The new ZESA®/GESA® NEXTG3N generation of butterfly valves from ARI-Armaturen ensures less turbulence thanks to an optimised disc design. This results in shorter inlet and outlet pipework sections. From DN 250 onwards, you benefit from the low weight and high stiffness of the honeycomb disc. The polygonal connection of shaft and disc ensures stable operation of your plant thanks to high torque transmission. These innovations lead to greater efficiency, which is reflected in improved Kvs values, greater ease of servicing and a more compact plant design.
