Brand Background of Humphrey
Founded in 1901 in the United States, Humphrey Products specializes in the field of pneumatic and fluid control, renowned for its high reliability, compact design, and adaptability to various scenarios. Its products are widely applied in industrial automation, medical equipment, analytical instruments, and other fields.
The 310 36 solenoid valve belongs to Humphrey's classic 310 series and is a direct-acting three-way solenoid valve specifically designed for small- to medium-flow pneumatic systems. Its core advantages include:
• Compact Structure: With dimensions of only 2.38×0.75×1.25 inches (approximately 60×19×32mm) and a weight of 113 grams, it is suitable for scenarios with limited space.
• Versatile Configuration: Supports normally closed (NC), normally open (NO), flow diversion, or selector functions, allowing flexible switching between two-way and three-way modes through plug ports.
• Media Compatibility: Suitable for air, inert gases, and vacuum environments, meeting the requirements of oil-free clean systems.
Core Technical Features
Direct-Acting Poppet Valve Design
• No pilot pressure is required; the valve core is directly driven by electromagnetism, enabling extremely fast response times (12ms/20ms for opening/closing) and supporting high-frequency operation (up to 600 cycles per minute).
• The sealing materials are nitrile rubber (NBR) and polyoxymethylene (acetal), which are wear-resistant and corrosion-resistant, extending the service life by 30%.
Wide Pressure and Temperature Adaptability
• Pressure Range: 0–125 PSI (approximately 0–8.6 bar), with support for -28 inches of mercury (approximately -0.95 bar) in vacuum environments.
• Temperature Range: Ambient temperature of 32–125℉ (0–52℃), with liquid-contacting components tolerating media temperatures from -40℃ to 120℃.
Electrical Safety and Energy Efficiency
• Voltage Specifications: The 310 36 model operates at 120V AC/50-60Hz, with a voltage tolerance of ±10%/-15% and a power consumption of only 4.5W, providing significant energy savings.
• Protective Design: The coil is fully encapsulated, and the electrical interface complies with the DIN Micro Type C standard (9.4mm), offering dust and moisture resistance.
Typical Application Scenarios
Industrial Automation
• Control of pneumatic actuators (such as robotic gripper claws and cylinder reversing), maintaining stability in high-frequency start-stop scenarios.
Medical and Analytical Equipment
• Flow switching in vacuum sampling systems and gas analyzers, relying on oil-free clean design to avoid contamination.
Energy Equipment
• Control of gas valves and inert gas protection systems, withstanding corrosive environments (stainless steel valve bodies are available as an option).
