leveling valve , Iran
Hydronic balancing valves are constructed from brass alloy CUZn39Pb3 or ductile iron EN-GJS-500-7. These valves withstand a maximum working pressure of 16 bar and operational temperatures from -10 to 120 degrees Celsius. The integrated flow meter offers a measurement accuracy of ±5% of the read value. Their adjustment screw typically allows 4 to 6 full turns with an internal locking mechanism. This design enables precise flow balancing from 0.2 to 10 cubic meters per hour. The valve features two pressure gauge ports for measuring differential pressure from 0.1 to 1 bar.
The valve structure incorporates a conical disc or needle valve mechanism with PTFE seals. Its designed pressure drop in the fully open position is below 3 kPa. Advanced valves feature analog or digital displays with a calibration precision of 0.005 m³/h. They offer BMS integration capability via a 0-10 Volt output. Sealing materials use EPDM or Viton for compatibility with various media. The mechanical lifespan of the connections exceeds 50,000 full adjustment cycles. These specifications stabilize fluid flow with less than 2% deviation.You can order and buy leveling valve from Iran by contacting us through whatsaap and email.

Balancing Valve Selection Based on Flow Rate in Iran
Correct balancing valve selection requires precise design flow rate calculation. This flow rate is defined in cubic meters per hour or liters per second. First, the existing pressure drop in the circuit is calculated. Then, the valves hydraulic characteristic curve is analyzed. The valve must operate within its linear performance zone. The valves Kv coefficient is calculated or selected for the design flow. Accurate flow rate selection prevents cavitation and noise. This maximizes the hydraulic efficiency of the system. Finally, a valve with a nominal flow rate close to the calculated value is chosen.
