Gate Valve Seat Seals

Discover why gate valve seat seals are needed and what to consider before ordering replacement parts.

Inner Diameter (ID) and Outer Diameter (OD) face seals used in type FLS gate valves and FLR-R slab gate valves are some of the most commonly replaced parts in this type of valve. These seals sit inside the grooves of the seat and seal on the seat pockets on either side of the valve. They also prevent any contaminants from entering the valve body which otherwise can cause damage and make for much more costly repairs.

Common Gate Valve Seat Seal Sizes and Pressure Ratings

These FLS ID and OD face seals are used in all sizes of valves. The valves range from 1-13/16” to 7-1/16” and require both an ID and OD face seal on each seat in the valve. Face seals from Heshka Oil have been qualified to pressures ranging from 300 PSI all the way up to 22,500 PSI to give you the peace of mind that when you install them in your equipment, they will seal the first time.

Heshka has an extensive stock of ID and OD face seals for the FLS and FLS-R style valves in all sizes.

Materials That Are Commonly Used for Gate Valve Seat Seals

In addition to the multiple sizes, each size can be made from the materials needed for your application. Heshka Oil even has proprietary blends of Teflon and PEEK materials that are tailored to specific operating conditions.

Are you operating in conditions where there is H2S, CO2, brine, acids or other harsh media? As a manufacturer Heshka Oil has a material solution for you.
