Válvula solenoide de fluido Instalação e resolução de problemas

Melhores práticas de instalação:

  • Always install the valve in the correct flow direction as indicated by an arrow on the valve body.
  • Ensure the fluid is clean and free of particulate matter; install a strainer or filter upstream if necessary.
  • Verify coil voltage matches the power supply. Use appropriate wiring and connectors.
  • Apply thread sealant (PTFE tape or liquid sealant compatible with the fluid) to male threads for a leak-tight connection.
  • Mount the valve in an orientation recommended by the manufacturer (often solenoid upright).

Dicas comuns de resolução de problemas:

  • Valve Fails to Open/Close: Check power to coil, coil continuity, correct voltage, pressure (min/max operating pressure), and for blockages or stuck plunger/diaphragm.
  • Leakage: Inspect seals/diaphragm for damage, check fitting tightness, look for cracks in valve body. Ensure correct seal material for the fluid.
  • Coil Burnout: Caused by incorrect voltage, continuous energization of an intermittent duty coil, or a mechanically jammed valve.
  • Chattering/Noise: May indicate incorrect pressure, AC hum (on AC coils, a shading ring issue), or fluid hammer.

Válvula solenoide de fluido FAQs

Material selection is critical for compatibility and valve longevity:

  • Brass Body: Good for neutral fluids like air, water, light oils. Cost-effective.
  • Stainless Steel (e.g., 304, 316): Excellent for corrosive fluids, food/beverage, high temperatures/pressures.
  • Plastic Body (e.g., PVC, PP, PVDF): Suitable for specific chemicals where metals might corrode.
  • NBR (Buna-N) Seals: General purpose for oils, water, air. Limited temperature and chemical resistance.
  • EPDM Seals: Good for hot water, steam, some chemicals. Not suitable for petroleum oils.
  • Viton® (FKM) Seals: Excellent for fuels, oils, many chemicals, and higher temperatures.
  • PTFE (Teflon®) Seals: Extremely wide chemical resistance, good for aggressive media.

Always consult a chemical compatibility chart or our technical team with details of your fluid, temperature, and pressure.

The primary differences lie in the materials of construction:

  • Valves for Air: Often use brass or aluminum bodies with NBR seals, which are cost-effective and suitable for neutral, non-corrosive air.
  • Valves for Aggressive Fluids: Require materials that resist corrosion and chemical attack. This typically means stainless steel (e.g., SS316L) or specialized engineered plastic (e.g., PVDF, PTFE) bodies. Seal materials are also critical, with PTFE, FKM (Viton®), or FFKM (Kalrez®) often used depending on the specific chemical, concentration, and temperature.

Using an air valve for aggressive fluids can lead to rapid corrosion, seal degradation, leakage, and valve failure, posing safety risks.

  • The ability of a solenoid valve to handle high-viscosity fluids depends on several factors:

    • Valve Design: Direct-acting valves with larger orifices are generally better for viscous fluids than pilot-operated valves with small pilot channels that can clog.
    • Fluid Viscosity: Manufacturers usually specify a maximum viscosity limit (e.g., in Centistokes, cSt) for their valves.
    • Pressão de funcionamento: Higher pressure can help push more viscous fluids through the valve.
    • Temperature: Viscosity often decreases with increasing temperature. Operating at a suitable temperature can help.

    For very viscous fluids, standard solenoid valves may not be suitable, and specialized valves like angle seat valves, ball valves with actuators, or pinch valves might be better alternatives. Always check the valve’s specifications for viscosity limits.

Regular maintenance ensures longevity and reliability:

  • Keep Fluid Clean: Install and regularly clean an appropriate strainer or filter upstream of the valve to prevent particulates from damaging seals or clogging orifices.
  • Inspect for Leaks: Periodically check for any external or internal leakage.
  • Check Electrical Connections: Ensure coil connections are tight and free from corrosion.
  • Monitor Performance: Note any changes in response time, noise, or incomplete opening/closing.
  • Seal/Diaphragm Replacement: For serviceable valves, replace worn seals or diaphragms as part of a preventive maintenance schedule, especially in critical applications.
  • Clean Internal Parts (if serviceable): Periodically, the valve may need to be disassembled and internal parts cleaned, especially if handling fluids that can leave deposits. Always follow manufacturer instructions.

Fluid temperature is a critical factor:

  • Seal Material Compatibility: Each seal material (NBR, EPDM, Viton®, PTFE, etc.) has a specific operating temperature range. Exceeding these limits can cause seals to harden, soften, swell, or degrade, leading to leaks or valve failure.
  • Coil Temperature: The fluid temperature can affect the solenoid coil’s operating temperature. High fluid temperatures can contribute to coil overheating, especially if the ambient temperature is also high. Most coils have a maximum rated temperature.
  • Fluid Viscosity: Temperature significantly impacts fluid viscosity. Higher temperatures generally lower viscosity (making flow easier), while lower temperatures increase viscosity (potentially hindering flow, especially for pilot-operated valves).
  • Valve Body Material: Extreme temperatures can affect the mechanical properties and pressure rating of the valve body material.

Always select a valve with body and seal materials rated for the minimum and maximum fluid temperatures expected in your application. Consider both operating and non-operating (ambient) conditions.
