Brand Name: Sinro
Model Number: SPV03 series
Place of Origin: Guangzhou,China
SPV03 series flow balancing valve consists of flow sensor and SBV characterized opening ball valve, which has equal percentage flow characteristic. The sizes are from DN20 to DN50. Users can preset the flow limit under maximum Kv rating according to terminal design request. When fluid pressure in HVAC system changes resulting in the change of flow rate, the actuator could adjust the valve opening dynamically and maintain the flow rate at the set range. When flow sensor detects the actual flow rate less than the preset flow rate, the actuator receives thermostat signal to control the valve opening. When flow sensor detects the actual flow rate more than the preset flow rate, the actuator receives flow sensor signal to control the valve opening. Then the flow rate could be maintained at the set range all the time.
