Multi-Functional Pump Control Valve
The Test Torque required for a Multi-functional Pump Control Valve typically depends on the Nominal Diameter (DN), the pressure rating (PN), and the design of the valve’s actuation mechanism (e.g., electric, pneumatic, or hydraulic). The Test Torque is important to assess the force needed to open and close the valve, especially in the cases of controlling flow and regulating pressure.
Multi-Functional Pump Control Valve
The Multi-Functional Pump Control Valve is an advanced control valve designed to combine multiple protection and control functions in a single device for pumping systems. This valve integrates flow control, pressure relief, check valve, and slow-closing features, providing comprehensive pump and pipeline protection while optimizing system efficiency.
The valve operates automatically, responding to changes in system pressure and flow without external power. By preventing water hammer, reverse flow, overpressure, and sudden pump starts or stops, it ensures smooth operation, reduces maintenance costs, and prolongs the life of pumps and pipeline networks.
Widely applied in municipal water supply, wastewater treatment, irrigation systems, industrial pumping stations, and hydropower projects, this valve is ideal for modern automated water distribution systems.
