Flow Restrictor/Orifice Component – Chemical Manufacturing

Component Specifications

Definition

A calibrated orifice or restrictor component installed in Water for Injection (WFI) distribution manifolds to precisely control and limit fluid flow rates, ensuring consistent pressure and flow characteristics throughout the pharmaceutical or biotech fluid distribution system.

Working Principle

Operates on the principle of creating a controlled pressure drop across a precisely sized orifice, converting fluid pressure energy into kinetic energy and turbulence to regulate flow according to the Hagen-Poiseuille equation and Bernoulli's principle.

Materials

316L stainless steel (ASTM A240/A276), electropolished to Ra ≤ 0.38 μm, with FDA/USP Class VI compliant elastomers (EPDM or PTFE) for seals

Technical Parameters

Surface Finish ≤ 0.38 μm Ra
Connection Type Tri-clamp, sanitary flange, or weld ends
Pressure Rating 10 bar (145 psi) maximum
Orifice Diameter 0.5-10 mm
Temperature Range 0-121°C (sterilization)
Flow Coefficient (Cv) 0.01-2.5

Standards

ISO 2852, ASME BPE, 3-A Sanitary Standards, DIN 11864

Frequently Asked Questions

What is the purpose of a flow restrictor in WFI distribution?

To maintain consistent flow rates and pressures throughout the distribution system, prevent over-pressurization of downstream equipment, and ensure proper sanitization flow velocities during CIP/SIP cycles.

How often should flow restrictors be calibrated or replaced?

Annual calibration is recommended, with replacement every 3-5 years or when flow characteristics deviate by more than 10% from specifications due to wear or fouling.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
