Frequent Interrogation

These valves are commonly used in marine, offshore, and water treatment systems, where corrosion resistance and reliable flow control are essential.

Aluminium bronze offers excellent resistance to seawater, brine, and chemical attack, making it ideal for harsh environments that would damage standard materials.

A wafer pattern design allows the valve to be clamped between flanges using through-bolts, keeping the overall assembly compact and easy to install in tight spaces.

The valve is powered by a Valpes electric actuator, which automatically opens or closes the butterfly disc when signalled, providing smooth, accurate control.

Yes, modulating versions are available that work with 4–20 mA or 0–10 V control signals, allowing precise adjustment of valve position for accurate flow management.

They are popular in marine cooling systems, desalination plants, chemical dosing, and HVAC automation, thanks to their corrosion resistance and dependability.

Yes, all Valpes electric actuators feature a manual override and a clear visual position indicator, enabling safe operation during power loss or system maintenance.

Standard sizes range from DN50 to DN300, with larger diameters available upon request depending on torque and actuator configuration.

Absolutely. Valpes actuators are IP67-rated, offering complete protection against dust and water ingress, perfect for outdoor or marine installations.
