Solenoid Valves: Double lock E1

Double Lock E1 solenoid valve for secure fluid flow control

The Double Lock E1 solenoid valve from HBS Valves is designed for hydraulic applications where reliable shut-off, controlled flow and safe load holding are essential. As part of the HBS Valves range of solenoid operated valves, this valve offers a dependable solution for demanding hydraulic systems that require precise fluid flow control under high-pressure conditions.

In the de-energized condition, the Double Lock E1 blocks flow in both directions, from port 1 to port 2 and from port 2 to port 1. When the valve is energized, the internal poppet opens and allows flow in both directions. This makes the Double Lock E1 especially suitable for systems where movement must be prevented when the valve is not activated.

By blocking flow in both directions, the valve helps maintain hydraulic stability and supports safe machine operation. This is particularly important in applications where static loads need to be held securely or where uncontrolled movement could affect performance, reliability or operator safety. As a compact two-way solenoid valve, the Double Lock E1 combines electrical control with mechanical hydraulic performance, making it a practical choice for automated machines, mobile equipment and industrial systems.

Designed for high-pressure hydraulic solenoid valve applications

The Double Lock E1 is developed for use in high-pressure hydraulic circuits up to 350 bar. This makes it suitable for demanding hydraulic solenoid valve applications where oil flow must be controlled safely and efficiently. In hydraulic systems, valves often need to handle high forces, changing loads and repetitive operating cycles. The Double Lock E1 supports these conditions by providing secure shut-off when the coil is not energized and free flow when electrical actuation is applied.

This HBS Valves solution can be used in a wide range of hydraulic applications, including lifting systems, mobile machinery, agricultural equipment, construction machinery, cranes, platforms and industrial hydraulic units. In these systems, controlled flow is essential for managing actuators, holding loads in position and preventing unwanted movement.

Although a solenoid valve is not always the same as a dedicated pressure control valve, the Double Lock E1 can support pressure-related functions within a hydraulic circuit. By blocking flow in both directions in its resting state, it can help isolate parts of a system and maintain hydraulic stability. This makes the valve valuable in applications where load holding, pressure retention and controlled movement are important.

How the Double Lock E1 solenoid operated valve works

The Double Lock E1 works through electromagnetic actuation. Like other electromechanical valves, it uses a solenoid valve coil to change the valve position. When the coil is de-energized, the valve remains closed in both flow directions. This means hydraulic fluid cannot pass from port 1 to port 2 or from port 2 to port 1.

When the coil is energized, a magnetic field is created, the poppet opens and flow is allowed in both directions. This makes the valve highly suitable for automatic control systems. Instead of relying on manual operation, the valve can be controlled electrically by the machine or hydraulic control system. This allows for fast response, repeatable switching and efficient integration into modern fluid power circuits.

For correct operation, the continuous duty coil must be ordered separately. This allows the valve to be matched with the correct voltage, current type and connector configuration for the installation. Selecting the right solenoid valve coil is important for reliable long-term performance and compatibility with the electrical system.

Benefits of the Double Lock E1 in industrial fluid control

The Double Lock E1 offers several benefits for industrial fluid control systems. Its main advantage is the ability to block flow in both directions when the valve is not energized. This supports load holding, improves system safety and helps prevent unintended hydraulic movement. In applications where stability is critical, this double locking function can be a major advantage.

Another benefit is its suitability for automated systems. Because the valve is electrically controlled, it can be integrated into machine control panels, PLC systems and other automated hydraulic circuits. This makes it easier to control hydraulic functions with precision and consistency.

The valve also supports compact system design. Solenoid operated valves are often used in manifolds, cartridge valve assemblies and space-limited hydraulic installations. This makes the Double Lock E1 suitable for both mobile and stationary equipment where reliable performance must be combined with efficient use of space.

While pneumatic solenoid valves are commonly used for compressed air systems, the Double Lock E1 from HBS Valves is specifically designed for hydraulic applications where higher pressures and load-holding capabilities are required. This makes it a strong choice for hydraulic systems that demand secure shut-off and controlled flow.

Choosing the Double Lock E1 for your hydraulic system

Choosing the right solenoid valve depends on the required flow direction, working pressure, medium, electrical configuration and system function. The Double Lock E1 is a suitable option when a hydraulic circuit requires flow to be blocked in both directions in the de-energized state and opened in both directions when energized.

This makes the valve especially relevant for systems where safety, load holding and controlled hydraulic movement are important. Whether used in mobile machinery, industrial equipment or high-pressure hydraulic systems, the Double Lock E1 provides dependable fluid flow control and supports efficient machine operation.

For applications that require a reliable hydraulic solenoid valve with double locking functionality, the Double Lock E1 from HBS Valves is a practical and robust solution.
