Latching Poppet Valves feature direct-acting solenoid.
Press Release Summary:
With pressure range from vacuum to 125 psig and 0.42 Cv flow rate, Series 315L/415L offers 3-way and 4-way porting configurations and is available with 1/8 in. NPSF ports for in-line mounting. Momentary electrical signal changes valve's position, and magnetic latching mechanism maintains position until another signal returns valve to original position. Latching feature eliminates need for external air supply or continuous current to maintain position.Original Press Release:
Humphrey Introduces 315L/415L Series Latching Solenoid Poppet Valves
Humphrey Products Company has introduced the 315L/415L Series latching poppet valves having a single direct-acting solenoid that is designed for reliable operation. A momentary electrical signal changes the valve's position. Then the magnetic latching mechanism maintains that position until another signal returns the valve to the original position. This ensures continuous operation in a particular mode, even in the event of a facility power failure.
The latching feature on the 315L/415L Series valves enables designers to replace a double coil or double solenoid valve, saving space. It also eliminates the need for an external air supply or continuous current to maintain position, saving money. The poppet design needs no lubrication and can perform under adverse conditions. And the high 0.42 Cv flow rate in a compact size reduces the overall footprint of the design.
The 315L/415L Series valves have a pressure range from vacuum to 125 psig. The 3-way and 4-way porting configurations offer design flexibility. They are available with 1/8" NPSF ports for in-line mounting, and for use on Humphrey's range of standard and custom manifolds.
