Product Name: Model 41-09 Differential Pressure Relief Valve
Size：DN65~DN400 Flange
DN50 Thread
Temperature: 0℃~100℃, Water
Features:
1. Accurate Differential Pressure Control
2. Maximum Flow
3. Reliable Hydraulic Operation
4. Closed Drip-seal 、Reliable Sealed
5. Completely Automatic Operation
Applications:
The Model 41-09 Differential Pressure Relief Valve maintains a water differential pressure across a centrifugal pump regardless of variable upstream supply or downstream demand.
By maintaining a constant differential pressure across a centrifugal pump operation at a known capacity, the maximum flow rate is controlled.
