Frese ALPHA flangeventil

Frese ALPHA Wafer

Flanged ductile iron

The ALPHA valve is particularly designed and manufactured for the automatic balancing of both cooling and heating circuits. With the ALPHA cartridge as an integral part of the valve, the flow is limited at the specified even under fluctuating pressure conditions.

This Frese ALPHA wafer-type valve can contain, depending on the size and the design flow, up to 85 Frese ALPHA cartridges.

Specification

The valve shall operate by means of automatic balancing stainless steel cartridges with replaceable orifice plate and internal diaphragm. The pressure class of the valve shall be PN16/PN25. The valve housing shall be made of ductile iron. The valve shall comply with flanges according to EN/ANSI standards.
