It is extremely important to automate the systems of a boat and to have reliable and trusted products in the nautical industry. Since its foundation in 1968, Comparato has specialized in the production of actuators for motorised valves, which is the company’s core business and leading production area.
Comparato brand is built on values such as quality and reliability, addressing a market that demands a high level of specialisation and continuous pursuit of innovative technologies.
Application of motorised valves
Motorised valves are essential on ships, yachts, and boats for fire-fighting systems and sea intakes management, where they shut off hydraulic circuits when engines are off. Both 2-way and 3-way valves are used to divert between sea intake and bilge water when needed.
Automation is also critical for handling wastewater, redirecting it to collection tanks, treating ballast water, managing transverse balancing systems, and disposing of oily residues. Motorised valves in these applications ensure that flows are redirected to collection tanks if they don’t meet standards for oily residues.
A wide and varied range
In a sector with limited space, Comparato motorised valves offer an automated and removable system controlled from a panel, providing significant time and cost advantages for operators and maintenance personnel. The company’s expertise has led to a broad range of motorised valves for various applications, including distribution systems, cabin heating, and wastewater management. Specifically, Comparato products are used in two main areas: the engine room and on-board services.
In the engine room
PRO Range motorised valves are designed for extreme applications. Models like Diamant PRO 11 Nm, Compact PRO 22 Nm, and Universal PRO 40 Nm feature IP67 or IP68 protection and various AC or DC power supply options, making them versatile. Ball valves in sizes from 1/4″ to 4″ and materials like stainless steel, PVC, cast iron, and brass are recommended to prevent corrosion in harsh conditions. Butterfly valves with stainless-steel lenses and NBR sleeves are ideal for ballast systems, handling seawater for ballast based on load distribution.
Pneumatic versions and actuators up to 350Nm complete the range. Notable functions in PRO Range actuators include:
- Fail-Safe with backup supercapacitors for emergency operations during power failures
- SMART technology for maximum control precision
- Direct communication with modern BMS (Building Management Systems)
The SMART PRO series offers Wi-Fi or MODBUS protocols for remote control, analysis, and diagnostics. Comparato motorised valves support both ON/OFF and MODULATING control for various applications.
On-board services
Motorised mixing valves with integrated electronics, like 3-way control valves, ensure temperature precision and user simplicity. They feature a control unit and display with functions for fixed-point temperature settings and 0-10V voltage control. Applications include maintaining constant heat transfer flows or managing domestic water temperature. For small spaces or pre-assembled hydraulic kits, the Sintesi motorised valves offer a compact design ideal for thermoregulation and cabin temperature management. For pool water treatment, 2-way/3-way PVC valves are highly effective.
Comparato‘s flexibility also allows for custom solutions like motorised bronze valves, ON/OFF actuators for fluid diversion based on temperature or time, and swimming pool temperature management kits.
In addition to motorised valves, there is a whole range of hydraulic components that Comparato is able to produce according to special and specific design, such as stainless-steel manifolds, filters, separators and manifolds that can be used for various operations.
