DI (ASTM A536)
Hot / Cold Water
65mm - 600mm
- Ideal flow regulation characteristics, relative flow, and relative opening are linearly related
- Accurate valve opening indicator, accurate to 1% of full valve opening
- The best cut-off function
- Lock opening - reliable memory function
- Enhanced nylon handwheel, laser engraving valve opening, clearer scale, more accurate, and not easy to wear.
- The testing points with self-sealing pressure/flow are distributed on two side flanges. If the valve does not need to be debugged, the testing points can be replaced with a brass plug to avoid the phenomenon of measuring hole collision during transportation.
- From DN80, the valve is designed with a balancing chamber, the function is: small torque, easy opening, and closing can reduce vibration and noise in the process of testing and using, also can reduce the impact of the fluid media on the valve stem then reduce the security hidden danger.
