Humphrey MC41E1 Mini Rotary Solenoid Valve
Humphrey (USA) is a professional brand in the field of pneumatic control, and its MC41E1 series belongs to compact direct-acting solenoid valves, specifically designed for automated equipment with limited space. This series adopts a modular structure and supports 4-way fluid control (4-way). It directly drives the valve spool via electromagnetic force to switch the flow direction of gases or liquids, making it suitable for precision control systems such as laboratory instruments, medical equipment, and small-scale manipulators.
Core Design Features
Compact Structure
• Miniature Size: The valve body is made of lightweight engineering plastics/aluminum alloy, reducing its volume by 40% compared to traditional solenoid valves and weighing only around 120g, fitting narrow installation spaces (e.g., inside analytical instruments).
• Direct-Acting Drive: The electromagnetic coil directly acts on the valve spool without requiring pilot pressure assistance, achieving a response time of ≤15ms and ensuring reliability in high-frequency switching scenarios (e.g., 10 pulses per second control).
Multi-Way Control
• 4-Way Fluid Guidance: It supports 1 inlet port (P), 2 working ports (A/B), and 1 exhaust port (R), enabling simultaneous control of the extension and retraction actions of double-acting cylinders or switching the flow direction of multiple media.
• Bidirectional Sealing Design: The valve spool seals are made of NBR or FKM materials, withstanding a temperature range of -20°C to 80°C and compatible with air, inert gases, and low-viscosity oils (viscosity ≤22 cSt).
Electrical Compatibility
• Wide Voltage Adaptation: It offers four coil voltage options: 12VDC, 24VDC, 120VAC, and 220VAC, with power consumption as low as 4.5W (AC models), supporting direct drive by PLCs.
• IP65 Protection Rating: The coil housing is sealed against dust and water, making it suitable for humid and dusty industrial environments.
