Multistage Restriction Orifice
IPS Automation supplies multistage restriction orifice assemblies in India for applications where a large pressure reduction should be divided across multiple stages. Final design requires an engineering review of the actual liquid, gas or steam process conditions.
IPS Automation supplies multistage restriction orifice assemblies in India for applications where a large pressure reduction should be divided across multiple stages. Staging can help manage velocity, noise, vibration, cavitation or flashing risks when a single restriction is not suitable. Final design requires a complete engineering review of the actual liquid, gas or steam process conditions.
Multistage Restriction Orifice Selection in India
The number of stages, bore arrangement, spacing, materials and assembly configuration depend on the fluid properties, flow range, upstream and downstream pressures, temperature, piping geometry and allowable operating limits. Single-hole or multihole stages can be reviewed according to the calculation and project specification.
Calculation and Quotation Inputs
Please provide fluid composition and phase, minimum normal and maximum flow, upstream and downstream pressure, operating and design temperature, pipe size and schedule, piping material, required assembly material, flange or weld standard, allowable noise limit and inspection requirements.
Frequently Asked Questions
Why use multiple restriction stages? Dividing the total pressure reduction can help manage excessive velocity, noise and damaging flow conditions.
Is a multistage restriction orifice a standard off-the-shelf item? The operating geometry normally depends on the submitted process data and calculation, so each requirement should be reviewed for the stated duty.

Controlled High Pressure Reduction
The multistage design divides the total pressure drop across multiple stages, helping achieve large pressure reductions in a safer and more controlled manner.
Cost-Effective Alternative to Control Valves
For fixed flow restriction and permanent pressure reduction applications, a multistage restriction orifice can be a more economical and maintenance-friendly option compared with complex control valve systems.
Custom Engineered Design
Each unit can be manufactured according to process conditions, line size, pressure class, material grade, number of stages, bore configuration, and project-specific requirements. Improved Equipment Protection By controlling flow velocity and pressure drop, the assembly helps protect downstream piping, valves, instruments, and process equipment from erosion, vibration, and pressure shock.
Lower Noise and Vibration
Multi-stage and multi-hole configurations help distribute flow energy, reducing high velocity noise and vibration compared with a single large pressure-drop restriction.
Reduced Cavitation and Flashing Risk
By reducing pressure gradually, the assembly helps minimize cavitation in liquids and flashing related damage in severe process conditions.
Suitable for Severe Service Applications
Ideal for high pressure-drop, high flow, gas blowdown, pump recirculation, boiler feed water bypass, and other demanding process applications.
