1. It has an excellent endurance because of its small size and simple structure.
2. This valve can be used for the pressure regulation on the feed water from an elevated water tank of middle or high building to each floor.
3. Pressure adjusting is easy and allows ia stable control of flow.
4. The valve is designed to enable inside inspection by disassembling the upper part of valve so that maintenance is very convenient.
