In the context of ball or gate valves, "f8 trim" refers to a specific type of valve trim material and design that is suitable for high-performance applications. The "f8" designation typically indicates that the valve components are made from a specific grade of stainless steel, often with enhanced corrosion resistance and strength. This trim is designed to withstand high pressures and temperatures, making it ideal for demanding industrial environments. Overall, f8 trim ensures reliable performance and longevity in critical applications.

That is the handles, screws, face plate and everything except the rough in valve. The rough in is the main body of the valve that is installed in the wall before drywalling or putting the tub/shower in. The trim is put on after the walls are finished.
Seat leakage is defined as leakage that is internal to a valve-between the inlet and outlet sides of the valve-when the valve is in its closed position. It is not limited to leakage across the valve seat, but also encompasses all leakage across the valve trim when the valve is in the closed position. Leakage across internal trim seals, such as piston rings, and across trim-to-body seals, such as gaskets, can be counted as seat leakage. It is important to note that, while leakage through valve stem packing is of growing concern in the industry, governing industry standards address this type of leakage separately and do not consider it to be a form of seat leakage.

The manufacturer usually determines trims by code numbers. Kinka valves indicates that this trim material on their valves is 304 stainless steel (13% chromium, and nickel content).
F6 Trim means that STEM, BODY seating surface, GATE seating surface, bushing (or a deposited weld), for the backseat and stem hole guide, small internal parts that normally contact the service fluid, excluding the pin that is used to make a stem-to-gate connection (this pin shall be made of an austenitic stainless steel material) are made of a 13Cr material (typical specification type ASTM A276T410 or T420). See API STD 600 - 2009.
