Features
1.The reduced pressure effect is reliable,outlet pressure not inlet pressure and current capacity change influence.Both may reduce moves the pressure,and may rduce the static pressure.
2.Debugging ease of operation.Only must adjust first the pilot valve adjusting screw,can obtain precisely.Stable outlet pressure.
3.The energy conservation effect is good.The valve body used the entire channel to flow the linear direct curent type design,the pressure loses slightly,cur- rent capaity big,also volume small,the weight was light.
