What is a Latching Valve?

In a pulse valve, the reversal is carried out by a short current pulse to a magnet.

What are the benefits of Buschjost Latching Valves?

• Single coil system with permanent magnet

• Bi-stable solenoid valves

• Switching to OPEN/CLOSED position by short pulses of current

• OPEN position maintained without power consumption

• Extremely low power consumption

• Low self-heating

• Supplied by battery or solar power

• Valve can be switched from OPEN to CLOSED position with a pulse of current of reverse polarity

• Pulse design in combination with 82400 Click-on® series of valves

Where are they used?

These solenoid valves are suitable for applications with a battery or solar power supply

How do they work?

The force exerted by the permanent magnet is not enough to attract the plunger against the force of the spring. The valve is closed. A short pulse of current assists the force of a permanent magnet to operate the solenoid valve. After an interruption in the current, the permanent magnetic maintains the operating position reached without any power consumption.

An approximately 30 millisecond pulse of current is enough to guarantee switching. The valve is open. Another pulse of current of the same duration but reverse polarity forces the spring-assisted plunger back onto the seat of the valve. The valve is closed.
