Precision-machined sealing surfaces on control valve bodies designed for gasket installation to prevent fluid leakage.
Gasket surfaces are critical mating interfaces on control valve bodies where gaskets are installed to create leak-tight seals between valve components. These surfaces undergo precision machining to achieve specific surface finishes, flatness tolerances, and geometric profiles that ensure proper gasket compression and sealing performance under varying pressure, temperature, and fluid conditions in industrial applications.

Control valve gasket surfaces typically require 63-125 μin Ra (1.6-3.2 μm Ra) surface finish. Finer finishes may cause gasket slippage, while rougher finishes may not allow proper gasket deformation and sealing.
Flatness is measured using precision straight edges and feeler gauges per ASME B16.5 requirements, or with coordinate measuring machines (CMM) for critical applications. Maximum allowable deviation is typically 0.001 in/inch across the sealing surface.
Minor scratches or corrosion can often be repaired by re-machining within allowable thickness limits. Severe damage may require welding and re-machining or component replacement, following original equipment manufacturer specifications.
