All About Latching Solenoid Valves

While applications usually deal with a number of issues – power consumption, coil heating and extended cycle times are usually the most common. Humphrey has a solution to all these issues with one valve – called a latching solenoid valve.

What it does

Latching Solenoid Valve’s apply a short pulse of electricity to help recreate a ‘maintained’ state in the valve regardless of whether it’s open or closed. With standard solenoid valves – you’re simply applying that jolt of electricity to get a ‘momentary’ state in a valve (again – open or closed).

What makes it even more effective than its standard cousin is that the actual electrical current that’s needed to power it is incredibly short. In some cases, it only needs 20 to 50 milliseconds to do its work. Best of all – once the pulse has run through the valve itself, it will remain open or closed even after the power is removed and you coil is de-energized.

In a way – it’s a simple play on reverse polarity – which enables the signal to manipulate the valve one way or another. Simply put – positive polarity shifts the valve one way, negative polarity pulls it back the other way.

Some of the benefits include

• Remote and battery operated applications
• Situations where valves need to open and actuated for longer or more varied periods of time
• They come with built-in protection circuitry and are environmentally protected
• An excellent solution in highly flammable or combustible environments

Latching solenoid valves offer customers a tremendous energy savings potential in their applications as they operate using significantly less power than their counterparts. In addition, their continued versatility and application in newer settings such as valves for air, hydraulic and water controls – has opened a whole new window and world in which they can be leveraged; surely making them a valve that will be a staple of global manufacturing for years to come.
