Technical Data Sheet

The Series 20000 introduces an advanced solution in the field of 2/2-way normally closed solenoid valves, thanks to its combined acting operating principle, which merges the benefits of both direct and pilot-operated systems. The sealing diaphragm, similar to that used in the 18000 Series, is directly lifted by the moving core during the actuation phase, allowing the valve to open even without upstream pressure—a key advantage during system start-up or in depressurized lines. Its mechanical structure features a sleeve in AISI 304 stainless steel with laser-welded fixed core, paired with a yellow brass body, ensuring high durability, mechanical strength, and reliability for professional hydraulic applications.

The 30 mm (8000BH) or 36 mm (10000BH) coil, with Ø14 mm bore and class H insulation (up to 180°C / 356°F), is designed to withstand continuous cycles and harsh environmental conditions without loss of efficiency.
Sealing is ensured through selectable gaskets in NBR, EPDM, or FKM, depending on the fluid type and required temperature range. The internal design supports high differential pressures, even with large flow orifices, while maintaining a smooth and consistent operation.

In addition, the IP65 protection rating safeguards the coil from dust and moisture, ensuring reliable performance even in industrial environments.
Available with female threads in 3/8", 1/2", 3/4", and 1", the Series 20000 is compatible with standard installation layouts. With a maximum working pressure of 20 bar (290 psi), this valve is the ideal choice for systems that require reliable operation even without line pressure, combining performance, safety, and long-term efficiency.

Thermohydraulic systems, autoclaves, machine tool cooling systems, washing systems, irrigation systems, fire prevention systems, sanitation systems, pressure washers.

OPERATES WITHOUT MINIMUM PRESSURE
Thanks to its combined acting system, the valve can open even with zero upstream pressure, ensuring immediate operation during start-up or in depressurized circuits.


DESIGNED FOR HEAVY-DUTY APPLICATIONS WITH HIGH COIL STRESS
The 30 mm or 36 mm coil, with class H insulation (180°C / 356°F), ensures reliable and continuous performance even under intense cycling, thermal peaks, or harsh industrial conditions.


HIGH DIFFERENTIAL PRESSURE MANAGEMENT WITH LARGE FLOW ORIFICES
The internal design allows the valve to handle significant pressure differences, even with enlarged passage sections, delivering smooth and consistent actuation.


COIL PROTECTED AGAINST HUMIDITY
With IP65 protection and a dedicated enclosure, the coil is safeguarded against dust and moisture, ensuring reliable operation even in challenging environments.
