1. Consists of plastic body, swing disc and sealing parts with compact structure and fully automatic one way operation.
2. Full plastic metal free design eliminates rust and metal pollution for all kinds of corrosive fluid
transportation.
3. Medium pressure driven automatic operation with sensitive response prevents backflow and
contamination to protect pipeline and pump equipment.
4. Smooth inner flow channel features low resistance and jamming free operation with stable long term
sealing performance.
5. Applied in chemical dosing, water treatment, electroplating and desulfurization pipelines for corrosive medium one way protection.
1. One piece full plastic molding is light, corrosion resistant and rust free for harsh chemical working conditions.
2. Fully automatic one way check requires no power or manual operation, reducing maintenance cost with high automation.
3. Sensitive opening and closing prevents medium backflow and water hammer damage to equipment.
4. Multiple material options adapt to corrosive media of different temperatures and concentrations.
5. Thread, true union and flange connections enable easy installation and compatibility with plastic anti corrosion pipeline systems.
6. Dead angle free flow channel avoids residue and scaling, ensuring stable maintenance free long term operation.
