Valves for Water Treatment

1. Full Water Cycle Solutions:

Supported by Reliable, Efficient Product Portfolio
Backed by 15 years of industrial valve automation expertise, HEARKEN Flow delivers integrated, reliable, and efficient valve-actuator solutions for the entire water cycle (including raw water intake, water supply networks, wastewater treatment, and reclaimed water reuse). Its core product range is tailored to water treatment needs:
·Key Actuators: Quarter Turn pneumatic actuators (for fast on/off control), Scotch Yoke pneumatic actuators (high torque for large-diameter valves), and Quarter Turn/Multi-Turn electric actuators (for remote intelligent control in long-distance water supply networks);
·Matching Valves: Water treatment-specific pneumatic/electric valves (e.g., corrosion-resistant pneumatic PVC butterfly valves for acidic/alkaline wastewater, electric flange butterfly valves for large-flow supply networks, electric ball valves for precision flow regulation), plus accessories like limit switch boxes, valve positioners, and air filter regulators for system synergy;
·Eco & Quality Assurance: Compliant with ISO 9001 (quality management) and ISO 14001 (environmental management), aligning with the mission to "optimize water supply/wastewater plant operations and advance environmental sustainability" by reducing environmental impact throughout product design and production.
2. Advanced Water & Wastewater Applications:

Scenario-Specific Design with Overload Protection & Intelligent ControlFor advanced water and wastewater scenarios, HEARKEN Flow’s industrial valve actuators focus on overload protection + intelligent control, with scenario-driven features:
·Precision Control: Multi-Turn electric actuators integrate intelligent control systems; paired with valve positioners, they achieve ±0.5% accuracy in flow/pressure management—critical for wastewater processes like aeration tank air flow adjustment and sedimentation tank sludge discharge control, preventing efficiency losses from parameter fluctuations;
·Overload Safety: Built-in overload protection shuts down automatically if valves jam (due to impurities) or pipe pressure surges, reducing equipment damage risks—ideal for wastewater with high suspended solids prone to valve jamming;
·Compatibility & Customization: Offers OEM/ODM services to tailor actuator interfaces and control logic for client processes (e.g., membrane separation, disinfection systems). Electrical components use reputable brands (Chint, Omron) for long-term stability and lower maintenance costs.
3. Wastewater Treatment & Management:

Dual Assurance of High Compliance & Strong Adaptability With optimized internal design, HEARKEN Flow’s industrial actuators deliver high-precision control + fast response for wastewater treatment operations, while meeting strict industry standards:
·Core Performance: Optimized transmission structure enables 20% faster response (e.g., Quarter Turn pneumatic actuators for second-level on/off, suitable for emergency drainage and rapid gate switching in wastewater plants). High precision ensures stable operation of dosing and sludge dewatering systems, cutting chemical waste and energy consumption;
·Strict Certifications: Compliant with ISO 9001, IP67/IP68 (dust/water protection for humid, dusty wastewater plant environments), SIL (safety integrity), CE, and ATEX explosion-proof certification (for special wastewater with volatile gases, e.g., chemical wastewater);
·Lifecycle Support: 18-month warranty, lifetime technical support, and fast order handling (2-hour response for pre-sales inquiries, 48-hour follow-up for after-sales issues), minimizing unplanned downtime and ensuring operational continuity for wastewater plants.
