At Fleyenda Flow, we know that water treatment plants operate under extreme demands — from fluctuating water pressures and corrosive environments to round-the-clock valve actuation. For one of our end-users in the municipal water sector, outdated valve systems were creating bottlenecks in flow control, reducing energy efficiency and increasing maintenance frequency.

To help resolve these challenges, our team supplied a custom-built Electric Multi-turn Control Gate Valve, designed specifically for the high-performance, high-reliability environment of modern water treatment facilities.

The Challenge: High Frequency, High Humidity, Zero Room for Error

Water treatment processes require precise flow regulation, especially at intake points, filtration beds, and chemical dosing lines. However, plant operators face several persistent problems:

• Manual valves are slow to operate, leading to delays in emergency shutdowns or process adjustments.
• Environmental exposure — including flooding risk, high humidity, and wide temperature swings — quickly degrades standard actuators and control systems.
• Lack of feedback signals makes real-time monitoring difficult or impossible.
• Frequent start-stop cycles cause conventional actuators to overheat or fail prematurely.

The customer needed a smarter, more durable valve system that could support advanced automation while operating reliably in harsh outdoor conditions.

Our Solution: Electric Multi-turn Gate Valve Built for Harsh Duty

Fleyenda’s engineering team delivered a tailored solution using our Electric Multi-turn Gate Valve equipped with a robust actuator and corrosion-resistant stainless steel body. The valve integrated seamlessly into the plant’s SCADA system and addressed key pain points:

• IP68-rated enclosure for complete protection against water and dust — ideal for underground or flood-prone locations.
• ON/OFF multi-turn actuator with S4-30% duty cycle, supporting frequent start/stop operation without overheating.
• 4–20 mA and 0–10 V control signals, plus feedback via potentiometer or analog output for closed-loop automation.
• Rated pressure: 25 bar, ensuring stability during high-pressure intake and discharge cycles.
• Operating temperature: -40°C to +60°C and up to 95% humidity — reliable in all climates.
• Body material: 304 stainless steel, providing corrosion resistance in chemically treated or chlorinated water.

Impact: Streamlined Operations and Long-Term Reliability

Following installation, the water plant reported several immediate improvements:

• Faster response time for zone isolation and emergency operations
• Reduced manual effort and increased plant automation readiness
• Improved data accuracy via real-time valve position feedback
• Greater system stability even during storm events or heavy inflow periods

This upgrade not only enhanced current operations but also helped the facility lay the foundation for smart automation — including predictive maintenance and remote diagnostics.
