1. Good functional features, like high KV, high close-off pressure, power-off return. Now in the market,
most of the zone valve can't have the above features at the same time, but we can!
2. Good price. Usually with high close-off pressure, the valve's price is very high. But now with our new technical developing,
we can offer both good functions and good price product! For some model, the price is only USD15.00 upon order quantities(ex-work)!!
