ARI-ASTRA®

Combined flow regulating valve – straight through with flanges and special spindle seal

Description

eClass-No.:	37010203
Application:	Heating facilities, AIR conditioning facilities
Medium:	Water, water with cold-protection, etc.

High performance for you through the latest ari technology:

Ideal regulating properties through equal percentage characteristic up to a stroke of approx. 45% (linear characteristic curve in the regulating range above 45% stroke)
Exact adjustment accuracy through documented flow characteristic (in accordance with IEC 534 / VDMA 24423; measurement by „Delft Hydraulics“)
Tight shut-off through regulating plug with ptfe soft seal (also suitable for contaminated media)
Reliable seal through integrated, well-established and tested double seal system
(EDD / ASTRA® DN 15 – 200)
V-port plugs withstanding high dynamic forces within the entire stroke (DN 250 - 400)

Cost-effectiveness through simple handling:

Fine adjustment through user-friendly digital display design: accurate to 1/10 handwheel rotation; zero point adjustment can be fixed reliably; easy to read from above (position indicator at DN 250 – 400)
Cost savings through maintenance free design
Cost effectiveness through quality: exact compliance with your quality standards from the time you place your order through quality assurance in accordance with DIN ISO 9001
Variable measuring instrument connections (angle connections can be fitted)
Easy operation even in cramped spaces through upright handweel
Fast and easy to insulate through screw-down globe valve (in accordance with German energy saving regulations (EnEV))
Easily accessible measuring instrument connections above the flange
Dew point barrier integrated in the insulating cap
User-friendly through standard „open / closed“ display

Information / restriction of technical rules need to be observed!

ARI-Valves of EN-JL1040 are not allowed to be operated in systems acc. to TRD 110.

A production allowance acc. to TRB 801 No. 45 exists (acc. to TRB 801 No. 45 EN-JL1040 is not allowed.) The engineer, designing a system or a plant, is responsible for the selection of the correct valve.

Resistance and fitness must be verified (contact manufacturer for information, refer to Product overview and Resistance list).
