Component Specifications

Definition
A critical fluid control component that provides a precisely machined sealing surface and flow restriction orifice within fluid caps or body assemblies, designed to regulate flow rates, create pressure drops, and ensure leak-proof operation in hydraulic and pneumatic systems.
Working Principle
Creates controlled flow restriction through a precisely sized orifice, converting fluid pressure energy to kinetic energy while maintaining sealing integrity between mating surfaces to prevent leakage.
Materials
Stainless steel (AISI 304/316), brass (C36000), carbon steel (AISI 1018/1045), or engineered polymers (PTFE, PEEK) depending on application requirements.
Technical Parameters
  • Hardness HRC 45-55 for metallic versions
  • Surface Finish Ra 0.4-1.6 μm
  • Pressure Rating Up to 6000 psi
  • Orifice Diameter 0.5-10.0 mm
  • Temperature Range -40°C to 200°C
  • Flatness Tolerance 0.01 mm
Standards
ISO 4401, DIN 24342, ISO 17292, SAE J1926

Frequently Asked Questions

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.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
