Regulation balancing Valve - 12.000-13.000 | Brandoni

Brandoni 12.000 / 13.000 – Differential Pressure Control Valve

Brandoni 12.000 / 13.000 are automatic flow control valves with variable orifice. Series 12.000 operates with a diaphragm, while 13.000 uses a piston and V-port for enhanced flow modulation and stable control under varying load conditions.

Control Functions

With appropriate pilot circuit configuration, the base valve can be adapted for:

• upstream or downstream pressure regulation
• pressure sustaining or relief
• differential pressure control
• level control
• flow limitation
• automatic ON/OFF
• isolation on excess flow

Difference Between 12.000 and 13.000

12.000 uses a diaphragm with guided stem, bonnet, and spring. Preferred for general pressure regulation in water distribution networks.

13.000 uses piston and V-port. Suitable for applications requiring precise flow characteristics, stable control under variable loads, or operation at higher pressure classes.

Industrial Applications

Applied in pump stations, water supply networks, industrial water systems, distribution circuits, tank filling lines, and branches requiring hydraulic balancing or overpressure protection. Compatible with water and non-aggressive fluids.

Selection Criteria

Selection should be based on DN, flow rate, available differential pressure, required pilot function, PN, cavitation conditions, and pilot circuit maintenance requirements.
