ADVANTAGE
Summary:
o Streamlined body, combined floating-ball disc with cone-shape sealing surface, these insure no abnormal vibration and noise when the valve is in use. these can also reduce pressure loss, makes the scope of upstream pressure much wider than other pressure valves, and pressure output more stable.
O Unique Design:
o Streamlined body.
o Combined floating-ball valve clack.
0 Cone-shape sealing surface.
o Diaphragm type control.
0 Filter installed at the pipe system.
o Screw hole at the bottom can clear the sediment.
O Excellent corrosion protection:
o Inside and outside epoxy resin coating.
o Floating-ball and filter are both made of bronze.
Reliable health nature:
O Epoxy resin coating is up to the GB/T17219.
0 Sealing material are made of rubber and PTFE.
0 Trims are made of stainless steel or bronze.
Scope of application:
O Potable water supply, building construction and so on.
