Humphrey (an American company) is a professional manufacturer in the fields of pneumatic and hydraulic control, renowned for its highly reliable direct-acting solenoid valves. Its products are widely applied in industrial automation, mechanical power systems, and special equipment control.
Core Design Features of P7054-1-5 DC24V
Direct-Acting Drive Structure
• Utilizing direct-acting electromagnetic principles, the coil directly pushes the valve spool upon energization, achieving a response time of ≤15ms, suitable for high-frequency operation scenarios (such as packaging machinery and automated assembly lines).
• Zero-Pressure Differential Start-Up: It can operate under a 0 bar pressure differential, solving the challenge of low-pressure system start-ups.
Modular Sealing System
• Valve Body Material: Standardly equipped with a nickel-plated brass housing, it offers corrosion resistance up to ISO 9227 C4 level (suitable for weakly acidic/alkaline environments).
• Seals: NBR/FKM rubber seals are compatible with mineral oil, compressed air, and water-glycol media, with a temperature range of -20°C to +120°C.
Safety and Energy Efficiency Design
• Explosion-Proof Coil (Optional): Compliant with Ex IIB explosion-proof standards, it is suitable for petrochemical and dusty environments.
• Low-Power DC24V Coil: With a power rating of 4.5W, it supports ±10% voltage fluctuations and is compatible with PLC control systems.
Typical Application Scenarios
Industrial Pneumatic Control
• Cylinder direction switching (such as grippers and lifting mechanisms), supporting a lifespan of over 300,000 cycles.
Energy Equipment
• Fuel on/off control for gas turbines, with explosion-proof models meeting ATEX Zone 2 requirements.
Medical and Food Equipment
• Optional PTFE-sealed versions, FDA-certified, for sterile gas delivery systems.
Installation and Maintenance Guidelines
• Installation Orientation: The coil should be oriented vertically upwards to avoid side mounting, which can cause eccentric wear of the iron core.
• Pipeline Filtration: Install a filter with a rating of ≥40μm before the valve to prevent impurities from jamming the valve spool.
• Troubleshooting:
• No movement upon energization → Check voltage fluctuations or coil impedance (normal impedance ±10%).
• Internal leakage → Replace the valve spool seal kit (maintenance kit model SRK-HTDA6).
