Alpha Model Dynamic Type Balancing Valves  >>  Frese ALPHA Threaded Ball Valves

Frese ALPHA Threaded Ball Valves

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.

Specification
The valve shall operate by means of an automatic balancing cartridge with replaceable orifice plate and internal diaphragm. The pressure class of the valve shall be PN25. The valve housing shall be made of DR brass.

1. Brass valves Female/Female
Pressure rating shall be no less than PN25 equal to 2500 kPa static pressure. The valve housing shall be made of DR brass.

2. Brass Valves with union and handle
The valve shall consist of a flow limiting cartridge and an integral ball valve with handle. The housing shall have an external mechanical stop to ensure a 90° turn. It must be possible to fasten the information tag following the flow cartridge on to the handle. Pressure rating shall be no less than PN25 equal to 2500 kPa static pressure. The housing shall have one fixed threaded end and one union end for easy of installation. The valve housing shall be made of DR brass.

3. Ductile Iron Valves
The valve shall be made from ductile iron type GGG40 or corrosion resistant RG6 and shall operate by means of one or more flow limiting cartridges. The pressure class shall be PN16/PN25 upon certification. The valve shall comply to flanges according to EN/ANSI standards.

4. Flow limiting cartridge
The flow limiting cartridge shall regulate the nominal flow with anaccuracy of +/- 10%. Min 0,004 l/s . The cartridge shall offer possibility to change flow by means of an orifice plate. The cartridge shall be made of DR brass or stainless steel. The cartridge shall be constructed with an internal rubber diaphragm to avoid internal leakage and noise.

5. The Manufacturer
The manufacturer shall be ISO 9001 certified.
