L310 Latching Solenoid Valve Brochure

Product catalog summary

Overview: The document provides detailed specifications and ordering information for the Humphrey L310 Latching Solenoid Valve and associated manifolds and accessories. It highlights the energy-saving features, mechanical specifications, and electrical control requirements of the L310 valve.

Specifications: The L310 valve is a direct solenoid, latching type with a 3-port, multi-purpose function. It supports 1/8 PIPE ports and is suitable for air, inert gases, and vacuum with a pressure range of 28” Hg to 125 PSI. The valve operates within an ambient temperature range of 32° to 125°F and has a flow coefficient (Cv) of 0.24. It requires a minimum pulse width of 50 ms and consumes 12 watts of power.

Energy Savings: The L310 valve offers significant energy savings by requiring only a 50 ms pulse to shift positions, after which the latching function maintains the valve's position without continuous power. This feature is particularly beneficial for applications with long open periods or limited power supply.

Heat Management: Unlike standard solenoid valves, the L310 minimizes heat generation as it does not require energy to maintain its position, making it suitable for temperature-sensitive applications.

Applications: The L310 is versatile, supporting both normally closed and open functions, and can be used with the 410M manifold. It is compatible with Humphrey 310 and 410 Series valves.

Accessories: The document lists various accessories including DIN rail clips, pipe plugs, block-off plates, and valve mounting kits. Specific accessories for the L310 include the 8-288A mounting bracket and HS-2 DIN receptacle.

Ordering Information: The document provides a guide on how to order the L310 valve, specifying options for electrical entry, coil rotation, and voltage choices. An example order code is provided for clarity.

Electrical Control: The L310 requires a polarity switching method to operate, with wiring diagrams available for guidance. The valve uses a 2-wire system, with specific terminal designations for operation.

L310 LATCHING SOLENOID VALVE Developed from proven Humphrey 310 balanced-poppet technology, L310 latching valve is optimized for applications that demand low power consumption and low heat generation. ENERGY SAVINGS Standard single solenoid valves require electrical power while holding valve in energized position. However, a 50 millisecond pulse to L310 solenoid fully shifts valve from one position to other. Power is removed and latching function holds valve positioned, thereby offering significant energy savings. Valve remains in position until another 50 millisecond electrical pulse, of opposite...
