Connection method: female interface below DN50, flange interface above DN65; material of handwheel for adjusting balance valve, ABS below DN50. Nylon for DN65 ~ DN150, ductile iron for DN200 ~ DN500; manual adjustment for balance valve The wheel does not rise. The core will drive the valve core up or down. After the adjustment is completed, the handwheel will display the actual open position of the valve. The adjustment precision of all specifications of the handwheel is 0.1 turns; the valve has a memory device. The memory device is adjusted in the center of the handwheel.
After the balance valve is adjusted in the system, the memory device is locked, and after the balance valve is closed, it can return to the original opening height; each balance valve has two interfaces for measuring pressure. The specification is PT1 / 4 ", which can measure the pressure of the valve-secondary side and secondary side separately. It is used when adjusting the balance valve or when you need to measure the system pressure. Each interface is equipped with a copper measuring connector. The cap and the connector are connected by a plastic connection ring. The connection ring is divided into red and blue. Red represents the primary side of the high pressure, and blue represents the secondary side of the low pressure; the valve body type adopts a Y-type structure, and the Throttle plug uses P-type or V-type structure, which are more conducive to the linear adjustment of the balance valve.
