Features
- Since it is a spring system that closes the valve before the backflow occurs when the pressure is reverse or the water is cut off, it is highly safe and prevents water strikes.
- The valve body part equipped with a synthetic rubber disc.
- It can use for hot water up to 90°C.
- It can supply with water with low pressure drop.
- Since the pipe end core can install, it prevents the generation of red water.
- The valve body part has a cartridge structure, so it is easy to maintain.
- The noise during running water is less than 40 dB (at rated flow rate), which is as low as that of piping.
