常见问题

What is the primary function of an orifice seat?

The orifice seat serves dual functions: providing a precise sealing surface to prevent fluid leakage and containing a calibrated orifice to regulate flow rates and create controlled pressure drops in fluid systems.

How do I select the right orifice seat material?

Material selection depends on fluid compatibility, pressure requirements, temperature range, and corrosion resistance needs. Stainless steel offers corrosion resistance, brass provides good machinability, while polymers offer chemical resistance and lower cost.

What maintenance is required for orifice seats?

Regular inspection for wear, scoring, or erosion; cleaning to prevent clogging; and replacement when sealing surfaces degrade beyond specified tolerances. Proper torque during installation is critical to prevent deformation.
