Humphrey Solenoid Valve HA110-4E1-PSL-1L
Humphrey is a professional American manufacturer of pneumatic components, renowned for its solenoid valves that feature high reliability, modular design, and compact structure. These valves are widely applied in automated production lines, pneumatic control systems for mechanical equipment, and industrial robotics. The HA110-4E1-PSL-1L is a TAC-grade pilot-operated solenoid valve, emphasizing low power consumption and high response speed. It is compatible with a 24VDC power supply and is specifically designed for precision pneumatic circuit control.
Core Design Features
Pilot-Operated Structure
• Low-Power Drive: Utilizing the pilot-operated principle, it requires only a small electromagnetic force to control the pilot air path, with the main valve opening through pressure differential. The power consumption is ≤4.5W (referencing the 410 model in the same series), resulting in low coil temperature rise and a 30% extended lifespan.
• Wide Pressure Differential Adaptability: It supports an operating pressure differential of 0.04–125 psig (approximately 0.28–8.6 bar) and can still start stably under low-pressure or zero-pressure differential conditions, avoiding the sticking issues of direct-acting valves.
• Bidirectional Flow Design: The valve body supports bidirectional media flow (air/inert gases) with no restrictions on installation orientation, simplifying system integration.
Modular Functional Expansion
• PSL Suffix Function: The "-PSL" designation indicates the integration of a manual emergency switch, allowing for mechanical forced opening and closing of the valve during power outages to ensure safe equipment maintenance and emergency fault handling.
• Sealing System: The valve spool seal is made of NBR/FKM materials, with a temperature resistance range of -25°C to +80°C, compatible with dry air, non-corrosive gases, and low-viscosity lubricating oil mist.
Compact Interface and Protection
• 1/8" Interface (DN6): Suitable for small cylinders (bore diameters of 20–40mm) and precision pneumatic circuits, with a flow coefficient Cv of 0.14, meeting high-speed response requirements.
• IP54 Protection Rating: The coil housing is dustproof and waterproof, adapting to dusty and humid industrial environments (such as food processing and packaging machinery).
Typical Application Scenarios
Automated Production Lines
• Pneumatic circuit control for robotic grippers (e.g., automotive welding robots), with a response time of ≤20 ms, supporting high-frequency gripping actions (>5 times per second).
Packaging and Food Machinery
• Pressure switching for valve groups in filling machines, with FKM seals resistant to hot and cold cleaning agents and IP54 protection preventing liquid splashing damage.
Pneumatic Systems in Medical Equipment
• Gas pathway control for ventilators, featuring low-noise design (<50 dB) and lubrication-free design compliant with medical dust-free requirements.
The Humphrey HA110-4E1-PSL-1L provides a cost-effective solution for precision pneumatic control scenarios through its pilot-operated low-power architecture, emergency manual function, and wide pressure differential adaptability. Its compact design and industrial-grade protection (IP54) further enhance its irreplaceability in clean environments such as food and medical applications, making it an ideal choice for pneumatic actuators in automated equipment.
