ZMIN-A1 Metal Seated Flanged Gate Valves

The flange gate valve is a gate value of the flange, which is most common. The flange gate valve is stable and reliable during the pipeline, so the flange gate valve is often used on the high pressure line.


The metal sealing flange is a gate valve that refers to a gate valve of a metal material, typically comprising brass seals, stainless steel seals, and alloy steel seals.

Metal Seated Flanged Gate Valves VS Resilient Seat

1. Material:

The difference of Metal seated and resilient seat gate valve is seat material.But both body material can be CI/DI/WCB/SS

2. Pressure (Similarity):

For iron body gate valve, both metals seated and resilient seated can be Class125/150, PN10/16,5K/10K/16K

3. Range of Applications:

Metal seat gate valve can be used in high temperature and high pressure and corrosive media.

4. Installation (Similarity and Difference):

The use temperature of the metal seat gate valve can be high or low according to the requirements; the metal seat can generally be connected to high pressure;  There is no difference in connection.
