Supplier's note

  1. Technical Breakthroughs:

    • Viton Seals: Triple the chemical resistance of standard EPDM seals, enabling safe handling of concentrated acids/alkalis.
    • Pilot Operation: Reduces power consumption by 25% compared to direct-acting valves, ideal for energy-sensitive systems.
    • UPVC/CPVC Body: Resists corrosion 2x longer than PVC in acidic environments, extending lifecycle in harsh conditions.

  2. Version Selection Guide:

    • Base Model (12VDC): Best for low-power setups (e.g., residential irrigation).
    • Advanced Model (24VDC): Balances cost and performance for moderate-pressure chemical dosing.
    • Pro Model (220VAC): Industrial-grade solution for high-pressure (2.0 MPa) and extreme chemical resistance needs. With its 0.8s response time, it outperforms competitors by 30% in fast-acting systems.
