Products Description
Controlled by built-in overlapped or parallel-connected electromagnetic precursor valve, with advanced craft and reliable action;
Diaphragm of main valve adopts imported special rubber, with high anti-corrosion and resisting low temperature at -40° C;
Special stainless steel magnetic material never rust or generate remanent magnetism;
Close the main valve when the working pressure is 0.3-0.4MPa, and the small flow system will be 3-3.5L/min, which can be designed according to users' requirements.
