Anti-Cavitate Orifice Plate™

Engineered Flow Restriction Without Cavitation Damage

Restrict Flow’s Anti-Cavitate Orifice Plate™ is a purpose-built flow restriction device designed to reduce pressure while eliminating the damaging effects of cavitation in liquid piping systems.  Traditional restriction orifice plates can create localized pressure drops that lead to cavitation in high-energy systems.  Unlike traditional orifice plates or multi-stage designs, each unit is engineered specifically for your system’s flow conditions to ensure performance, reliability, and longevity.  Cavitation is controlled inside the Anti-Cavitate Orifice Plate™—not in the pipe.

What This Plate Is Designed To Do

The Anti-Cavitate Orifice Plate™ is designed for applications where a standard restriction orifice plate may create damaging cavitation.

 

It helps manage pressure drop inside the plate instead of allowing destructive energy to release downstream in the piping system.

 

Common goals include:

  • Reduce cavitation-related wear

  • Protect downstream piping and components

  • Limit noise and vibration

  • Fit between standard flanges

  • Avoid long multi-stage assemblies

Every Plate is Engineered — No Two Are the Same

Each Anti-Cavitate Orifice Plate™ is uniquely designed based on the exact operating conditions provided. No two plates are identical.

Design inputs include:

  • Flow rate (GPM)

  • Inlet and outlet pressure

  • Pipe size and schedule

  • Fluid type and temperature

This ensures that every plate is optimized for its specific application, delivering precise pressure reduction while mitigating cavitation at the source.

What Makes This Different

Cavitation Control Happens Inside the Plate

The key to the Anti-Cavitate Orifice Plate™ design is that cavitation and noise are mitigated inside the plate itself, rather than downstream in the piping system.

The plate is inserted between two flanges, just like a standard orifice plate, and requires no additional footprint. The overall space required is no more than a conventional flat orifice plate, allowing it to be implemented without modifying existing piping layouts.

​

One-Piece, Engineered Construction

Each Anti-Cavitate Orifice Plate™ is fabricated from a single piece of material and can be engineered from virtually any metallurgy required for the application.

  • No moving parts

  • No internal assemblies

  • No wet welds exposed to the process fluid

This results in a robust, predictable, and highly reliable flow element.

Single-Stage, Engineered Design

Traditional systems often require multi-stage orifice plates to manage high pressure drops. The Anti-Cavitate Orifice Plate™ uses a proprietary 3-dimensional design to achieve the required pressure reduction in a single stage.

Because each plate is engineered to the provided data set, performance is consistent and predictable—eliminating the variability commonly seen in standard or catalog-based designs.

Engineered Design Example

See the Anti-Cavitate Orifice Plate™ spec sheet developed for a specific set of operating conditions.

​

The spec sheet demonstrates how the plate

  • Fits within existing piping envelopes

  • Achieves targeted pressure drop

  • Controls fluid behavior through internal geometry

Note: The internal design of the Anti-Cavitate Orifice Plate™ is proprietary and not publicly disclosed. Each unit is custom engineered, and design details are protected to prevent replication and maintain performance reliability.

Eliminate Cavitation Damage

Cavitation is one of the leading causes of equipment failure in liquid systems. It leads to:

  • Erosion and corrosion

  • Loss of material strength

  • Reduced system performance

  • Increased maintenance and replacement costs

The Anti-Cavitate Orifice Plate™ mitigates cavitation internally, protecting both the plate and downstream equipment.

Replace Multi-Stage Orifice Plates

Multi-stage systems are often used when pressure drop requirements exceed the limits of a single plate. This adds:

  • Complexity

  • Cost

  • Installation challenges

  • Multiple potential failure points

 

The Anti-Cavitate Orifice Plate™ can eliminate the need for multi-stage assemblies in high differential pressure liquid systems by achieving the required pressure drop in a single engineered device.

Anti-Cavitate Orifice Plate versus multistage

Maintenance & Turnaround Advantages

Maintenance and inspection requirements are significantly reduced with the Anti-Cavitate Orifice Plate™ when compared to multi-stage designs.

Anti-Cavitate Orifice Plate™

  • One-piece construction with no wet welds

  • No pressure testing required

  • No bore scope inspections required

  • Minimal maintenance during plant turnarounds

  • Visual inspection can be completed in 30 seconds or less

Multi-Stage Orifice Plates

  • Multiple internal welds exposed to fluid (“wet welds”)

  • Require pressure testing to verify weld integrity

  • Often require bore scope inspection

  • Increased number of potential failure points​

  • Significantly longer inspection and maintenance time​

The result is reduced downtime, faster turnarounds, and lower lifecycle maintenance costs.
