BOSCH 0 820 026 552 – 5/2-Way Double Solenoid Valve

Description

### BOSCH 0 820 026 552 – 5/2-Way Double Solenoid Valve

The BOSCH 0 820 026 552 is a high-performance 5/2-way double solenoid valve, designed for precise control of compressed air flow. The valve is designed for reliable and repeatable operation, making it ideal for the control of double-acting pneumatic cylinders. Its bistable operation means it holds its position even after the electrical signal is removed. This makes it an energy-efficient design for applications where the valve needs to maintain a state for extended periods.

This valve is shown attached with two BOSCH 1 824 210 223 solenoid coils, which are rated for operation on a 24V AC or 48V AC electrical supply at 50Hz.

Key Features

• 5/2-Way Function: The valve has five ports and two positions, which is the standard configuration for controlling double-acting pneumatic cylinders.
• Double Solenoid Actuation: The valve is shifted by a solenoid on each side, providing control over its two positions.
• Bistable Operation: The valve holds its position even after the electrical signal is removed, which conserves energy.
• High Pressure Rating: The maximum pressure is typically between 10 and 12 bar.
• ISO Code 355: This is a standardized identifier for this specific valve type, ensuring compatibility.

About this Valve Function

The diagram on the label indicates a 5/2-way double pilot valve, commonly referred to as a double solenoid valve in electrical applications.

• 5/2-way: This denotes the valve’s configuration. It has five ports (one pressure inlet, two work ports, and two exhaust ports) and two positions. This design is a standard for controlling the extension and retraction of double-acting pneumatic cylinders.
• Double Pilot: The diagram shows that the main valve’s spool is shifted by compressed air signals, not a direct mechanical force. The valve has two control ports, labeled 14 and 12, each controlling one of the two positions.

Because the valve has two pilot inputs, it is bistable. It holds its position even after the air signal is removed. A new signal to the other pilot port is required to switch it back.
