Resilient seated gate valve: one side of the sealing is metal materials, and the other side is a "soft sell" of the elastic non-metallic material. This seal has a better sealing performance but does not high temperature, is easy to work, and has poor mechanical properties.

The difference of resilient seated and metal seated gate valve is seat material.For exzample, EPDM,NBR is for resilient seated, brass,Bronze and stainless steel is for metal seated. But both body material can be CI/DI/WCB/SS
For iron body gate valve, both resilient seated and metal seated can be Class125/150,PN10/16,5K/10K/16K
Resilient seat gate valve sealing effect is the best, medium cleanliness needs to be high and before operation strictly flush the pipeline.
Resilient seat gate valve will leak at too low or high a temperature, which requires a high temperature of the medium; not suitable for high-pressure environment.
Both of them could serve the same function of isolating the flow, however, the main difference is in the operation. While gate valves open by lifting a round or rectangular gate out of the path of the fluid, ball valves have a stem and a ball that turn horizontally.
Yes. Gate valves are mainly used for isolation, and they offer no resistance to the flow of water when gate valves is open.
