Its unique design helps saving electricity and enhancing the valve¡¯s durability. Instead of using a blocking-style screen, this valve adopts a mediating-style screen, which only filters a small amount of water that passes through the small pores. The filtered debris will be discharged automatically and users do not need to clean the screen, thus significantly reduces the chance of breakdown of the valve. This original design solves the common problem of valve clogging and enhances the safety and durability of the product. It is suitable to be installed in intelligent sensor water saving equipment, washing machine, dishwasher, solar water heater and industrial and agricultural automatic water control device
