Orifice Plates

Series A, Orifice Plate is an accessory for HD Main Valve to see more accessory options please visit the HD Accessories Section.

The Series A Orifice Plate with its drilled orifice pattern is installed after the pressure regulating valve to smooth out turbulence caused by the pressure drop across the regulator. Noise reduction levels of 5-10 dBA can typically be achieved. Manufactured from SA-105 Carbon Steel.

Product Overview
The Series-A Orifice Plate with its drilled orifice pattern is installed after the pressure regulating valve to smooth out turbulence caused by the pressure drop across the regulator. Noise reduction levels of 5-10 dBA can typically be achieved.
Selection / Sizing / Capacities
Selection: Series A orifice plates are custom engineered to maximize noise attenuation and reduce dbA to the lowest achievable value. The number and diameter of holes will be determined based on application conditions, and the plate diameter will typically be equal to the recommended downstream pipe size.

Therefore, the following information is required for selection:
• Inlet (Supply) Pressure to the HD/HSP Regulator
• Outlet (Downstream) Pressure of the HD/HSP Regulator
• Steam Flow Rate (lb/hr)
