    Features & Benefits

    SP41 is a balancing valve that uses the pressure changes of the medium itself for self-regulation, thereby maintaining a constant flow rate through the controlled system. It has flow indication, can be adjusted online, and is suitable for non corrosive media such as heating and air conditioning systems. Before operation, a one-time test adjustment can automatically set the system flow to the pre-set value. This valve has accurate flow adjustment, simple operation, smooth operation, reliable performance, and long service life.

    1. Ideal regulation performance; 
    2. Excellent cut-off function;
    3. Accurate display of the opening status up to 1/10 turn;
    4. The theoretical flow characteristic curve is an equal percentage characteristic curve;
    5. National patented opening and closing locking device;
    6. Corresponding to each full circle, there is a fixed flow coefficient. During debugging, as long as the pressure difference between the two ends of the valve is measured, the flow rate through the valve can be easily calculated;
    7. PTFE and silicone seals provide reliable sealing performance;
    8. The internal components are made of 304 or copper alloy, which has strong corrosion resistance and long service life;
    9. The internal lifting valve stem does not require reserved operating space.
