【English Introduction】
400X Series Flow Control Valve (Hydraulic Regulation Type)
Product Overview
The 400X series hydraulic control valve is an intelligent flow regulation device specifically engineered for pipeline systems. Utilizing a proprietary hydraulic transmission mechanism, this product achieves dynamic balance control of fluid media. It is suitable for water supply/drainage systems, industrial circulating water networks, and HVAC piping, providing automatic flow adjustment and pressure stabilization to ensure system safety while optimizing energy efficiency.
Structural Features
The valve body is manufactured through integral casting with high-strength alloy materials. Its internal structure incorporates precision flow-guiding components and pressure compensation modules. The multi-stage throttling design enables progressive flow regulation during operation, effectively mitigating water hammer effects. The diaphragm-type hydraulic actuator automatically adjusts the disc position based on real-time pipeline pressure changes, maintaining preset flow parameters.
Key Advantages
- Dynamic Response: Built-in pressure feedback system enables millisecond-level adjustment through real-time system monitoring.
- Broad Compatibility: Adaptable to various media environments within -20℃ to 120℃ temperature range, suitable for liquids with PH 6-9.
- Durability Assurance: Wear-resistant composite materials and specialized surface treatments ensure over 20,000 operation cycles.
- Energy Efficiency: Precise flow regulation reduces system energy consumption by 15%-30% while minimizing water resource waste.
Application Scenarios
This product is widely implemented in municipal water supply pressure zones, building secondary water systems, industrial park circulating networks, and central air conditioning distribution systems. It demonstrates particular effectiveness in complex piping scenarios requiring accurate flow control, maintaining stable performance even under significant pressure fluctuations.
