Berluto is a renowned manufacturer of pressure regulating valves and fittings for water, energy and industrial applications. As a valve manufacturer, we have been working in partnership with Berluto for many years and offer you the complete portfolio – from standard valves to individual special solutions. We provide you with manufacturer-independent advice, modify valves according to your requirements and supply complete systems from a single source.
For precise pressure control in water, steam and process lines.
Protection and barriers for sensitive systems.
For aggressive media, high temperatures or special standards.
Customization and integration into existing systems – including automation.
Efficient drainage
and filtration for steam and condensate systems.
Pneumatic and electric actuators, limit switches, solenoid valves and accessories – for the efficient automation of your processes.
Constant outlet pressure in compressed air and nitrogen networks despite a fluctuating inlet pressure.
The pressure-balanced series 6 needs low actuating forces even at a high inlet pressure.
Pressure maintenance in steam and hot water circuits up to 190 °C, without auxiliary power.
The series 5 is a single-seat diaphragm valve in gunmetal with a flanged connection.
The setpoint is matched to the operating point via interchangeable springs.
Diaphragm-controlled and spring-loaded – neither power nor control air required.
Fluctuations in the inlet pressure do not carry through to the set outlet pressure.
PED 2014/68/EU and AD2000 regulation HP0 for pressure equipment.
Valves for heating, steam and water applications in accordance with European standards.
Low actuating forces even at high inlet pressure – for larger nominal sizes.
The series 5 is designed as a single-seat diaphragm valve in gunmetal with a flanged connection.
Temperature versions of both series up to 190 °C.
The setpoint range can be changed via interchangeable springs.
We trade in Berluto pressure control valves and supply from the manufacturer range. The two series described below are the ones we supply most often – we can source the complete Berluto range, including series not listed here.
Both series are diaphragm-controlled single-seat diaphragm valves with inlet pressure compensation and a flanged connection. They regulate without auxiliary power – the diaphragm area works against the setpoint spring.
Inlet pressure compensation is the decisive feature: it ensures that fluctuations in the inlet pressure do not carry through to the set outlet pressure. Without it, the outlet pressure drifts as soon as the mains pressure changes.
| Series | Design | Features |
| Series 5 | single-seat diaphragm valve in gunmetal with flanged connection | inlet pressure compensation, setpoint ranges via interchangeable springs; operating pressures up to around 25 bar, temperature versions up to 190 °C |
| Series 6 | balanced single-seat diaphragm valve with flanged connection | additionally pressure-balanced – the actuating forces stay low even at a higher inlet pressure, so larger nominal sizes and pressure differentials can be handled; temperature versions up to 190 °C |
Series 5 is the economical choice at moderate inlet pressures and smaller nominal sizes. As soon as inlet pressure and nominal size increase, the actuating forces grow quadratically – then the pressure-balanced series 6 is the right design, because it handles considerably larger cross-sections with the same spring force.
For sizing we need three figures: inlet pressure, required outlet pressure and flow rate. From these follow the series, the nominal size and the spring range.
As a rule we supply Berluto products unchanged from the manufacturer range. Where the project requires it, the following can be added for Berluto:
Yes – series, spring range and material can be selected; further connections available.
For water, energy, heating, steam and process systems as well as industrial applications.
Yes, we supply ready-to-install units including fittings, accessories and documentation.
The starting point is your enquiry with medium, pressure and temperature. From this we size the appropriate Berluto version and agree the accessories and test scope with you.
Because the inlet pressure compensation holds the outlet pressure even when the mains pressure fluctuates – and because of our many years of experience as a partner.
