Product Description:
1. Core advantages of SMC solenoid valves
High-efficiency and energy-saving design
Ultra-low power consumption: Some models (such as SY5220-5DZ-01) consume only 0.1 watts of power when equipped with a power-saving circuit, which greatly reduces the energy consumption of the equipment.
Flow optimization: Maintain high flow (flow coefficient 0.59) and fast response (minimum response time ≤32ms) in a miniaturized valve body (such as the SY series) to improve system efficiency.
Excellent reliability and durability
Extremely long life: Wear-resistant materials and precision craftsmanship are used, with a service life of more than 50 million times, suitable for high-frequency action scenes.
Strong environmental resistance: Protection level reaches IP65/IP67 (some models), dustproof and waterproof, suitable for harsh environments such as humidity and oil pollution.
Flexible installation and compatibility
Various installation methods: Supports single installation of aluminum valve body, DIN rail fixing or combined assembly, saving space and simplifying wiring.
Mixed installation capability: Supports mixed use with 3-way valves to improve system integration flexibility.
Quiet and environmentally friendly features
Centralized exhaust structure: The exhaust of the pilot valve and the main valve is centrally processed to reduce oil mist and noise pollution.
Oil-free lubrication compatibility: Some models do not require additional oil supply, reducing maintenance costs (such as SY7320-5DZ-C8).
Wide applicability
Multiple voltage support: Compatible with multiple voltages such as DC 3V-24V and AC 100V-220V.
Wide fluid compatibility: Applicable to air, vacuum, water, oil and mild steam (specific models).
II. Key usage precautions
Wiring specifications and power management
Strictly distinguish polarity: DC solenoid valves need to distinguish between positive and negative poles, and AC solenoid valves have no polarity requirements; wiring errors may cause the coil or control element to burn out.
Voltage range control: The allowable voltage fluctuation range is -10% to +10% of the rated voltage. Overpressure can easily damage the circuit.
Leakage and seal maintenance
Check seals regularly: Aging or damaged seals (such as nitrile rubber) can cause gas leakage and need to be replaced in time.
Avoid overtightening: Excessive force during installation may squeeze the sealing material, which will reduce the sealing performance.
Risk prevention of no-load power-on
Long-term no-load power-on is prohibited: It is easy to cause valve core adhesion, coil overheating and even short circuit, which needs to be avoided through automatic control or regular testing.
Environmental and fluid adaptability
Temperature limit: The operating temperature is usually -10°C to 50°C (some models -10°C to 60°C), and high temperature will accelerate seal aging.
Lubrication requirements: If oil is required, ISO VG32 turbine oil should be used to avoid grease clogging the pilot hole.
Fault diagnosis and maintenance
Abnormal operation troubleshooting: Prioritize checking the power supply voltage, coil resistance value and valve core jamming (commonly caused by foreign matter blockage).
Noise treatment: Excessive intake pressure or pipeline vibration will cause noise, and the pressure needs to be adjusted and the fixture reinforced.
