Hydraulic Balancing Valve

      Aone-Best Balancing VALVES have two materials, the valves`s matreial below DN50 is bronze and the others are ductile iron. The valve`s core is brass. The seals are EPDM.

      The connection of DN50 or smaller size is threaded and the flange if used for DN65 or bigger size.

      The handwheel`s material of DN50 or smaller size is ABS, the material of DN65 to DN150 is NYLON, and DN200 to DN600 use ductile iron handwheel.

      When regulating the valve, the position of handwheel will not change. The stem will drives the valve`s core move up or down. After regulating, the real position of valve`s core will show on the handwheel`s scale. The accuracy of all handwheels is 0.1 cycles.

      The Balancing Valve has memory device. The memory device is adjusted at the center of the handwheel. When the balancing valve is adjusted in the system, lock the memory device. After the balancing valve is closed, it can return to the original opening position.

      Each balancing valve has two ports for measuring pressure, and the thread of ports is PT1/4 ". The pressure of inlet and outlet of the valve can be measured separately, which is used to adjust the balancing valve or to measure the system pressure. The ports are equipped with a copper measuring joint, and the joint cap and the joint are connected by a plastic connecting ring. The connecting ring is divided into two kinds: red and blue, red represents the inlet pressure, and blue represents the outlet pressure.
