定义
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.
工作原理
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.

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
标准
ISO 2852ASME BPE3-A Sanitary StandardsDIN 11864

常见问题

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.
