Description
ISI-Certified 6mm Orifice Plate for Fire Protection Systems
Overview
The ISI-Certified 6mm Orifice Plate is a precision-engineered flow control device designed to regulate pressure and restrict flow in fire sprinkler and water pipeline systems. Manufactured in compliance with stringent Indian Standards, this orifice plate ensures reliable performance for critical safety applications where accurate flow measurement and pressure reduction are essential.
An orifice plate is a simple yet highly effective device consisting of a thin plate with a precisely machined hole . Operating on Bernoulli’s principle, it creates a controlled pressure drop that can be used to measure or restrict fluid flow . When fluid passes through the orifice, velocity increases while pressure decreases, allowing for accurate flow regulation .
The 6mm orifice plate is specifically designed for applications requiring moderate flow restriction, typically used in fire sprinkler systems, hydrant networks, and water distribution pipelines to balance flow rates and maintain optimal system pressure.
