New Product Features:
The design of inner leakage control of general CHECK VALVE is almost rely on PTFE sheet to prevent leaking; however, PTFE sheet can not be used over a long period of time under high temperature, and the pollution is another serious problem to our enviroment. With the special improvement design, our CHECK VALVE has passing SGS Test on leakproofness, the product itself is all metal-design without any PTFE, thus, it is quite safe to be used under high temperature and high pressure. More Importantly, it is no harm to our Earth.
