Unloader valves (max 800 bar)

Emiltec offers a specialized selection of unloader valves designed for extreme high-pressure applications, with the max 800 bar category encompassing professional-grade valves capable of handling pressures from 350 bar up to 700 bar. These heavy-duty components are engineered for demanding industrial cleaning environments where conventional valves cannot perform.

Industrial-grade construction and materials

The unloader valves in this category feature robust construction with stainless steel bodies, primarily utilizing Aisi 303 stainless steel that ensures exceptional resistance to very high pressures. This premium material selection provides the structural integrity required for continuous operation in challenging industrial environments, including applications involving sandblasting, paint removal, and surface preparation processes.

Performance range and specifications

Our max 800 bar category encompasses by-pass valves with diverse performance capabilities to match specific application requirements. Flow rates range from 40 l/min to 250 l/min, with maximum working pressures spanning from 350 bar to 700 bar. This versatility ensures optimal valve selection for various pump configurations and industrial cleaning systems requiring extreme pressure capabilities.

Applications in demanding environments

These high-pressure unloader valves are specifically designed for industrial cleaning applications where standard valves cannot withstand the operational demands. Primary applications include industrial cleaning equipment, sandblasting systems, paint removal machinery, surface preparation processes, and descaling operations within steel mills. The valves handle the extreme pressures necessary for removing rust, preparing surfaces for coating, and hydrodemolition tasks.

Advanced features and configurations

Several models in this category offer advanced features including integrated microswitches for system integration, knob-included configurations for manual adjustment, and "easy start" systems that facilitate pump startup procedures. Some valves are available in multiple configurations to suit different installation requirements and operational preferences.

Leading manufacturers and quality assurance

Emiltec's max 800 bar catalog features unloader valves from renowned manufacturers including PA, Mecline, Hawk, and R+M. Each valve represents Made in Italy or Made in Germany quality standards, combining precision engineering with proven reliability in extreme pressure applications. The obsessive attention to design and construction details ensures these components can withstand the demanding conditions of industrial cleaning operations.

System safety and professional integration

These extreme high-pressure valves play a critical role in system safety by regulating pressure and protecting pumps from overload conditions. When the delivery line is closed, the valve diverts water to bypass, allowing the pump to operate without excessive strain. This fundamental protection mechanism extends equipment lifespan and prevents costly damage in industrial settings where pressures regularly exceed 300 bar.

Expert selection and technical support

As an ISO 9001:2015 and ISO 14001:2015 certified company based in Reggio Emilia, Emiltec provides specialized technical guidance for selecting the appropriate unloader valve for extreme pressure applications. Our experienced sales staff offers expert advice on valve sizing, pressure ratings, flow requirements, and proper integration with industrial-grade plunger pumps and high-pressure washing systems designed for professional industrial cleaning environments.
