Choosing the Right Retainer Plates


Discover what retainer plates do in type FC and FLS gate valves.

Retainer plates are used in the type FC gate valve on both sides of the gate. They act as the housing for the seat rings in the valve. FLS gate valves only use one retainer plate that sits at the bottom of the gate valve and keeps the seats in place during assembly.

It is not very often that the retainer plates will need to be replaced in your FC or FLS style gate valve, but when you do need them Heshka Oil has you covered. Type FC and FLS gate valve retainer plates are available directly from our warehouse. Read on to learn more about how a retainer plate is made and what to consider when you purchase replacement retainer plates.

Retainer Plate Construction Materials

FC style retainer plates are usually made from a 1018 carbon steel while the FLS retainer plates are usually a 300 grade of stainless.
