Each Universal Orifice Plate adheres to rigorous manufacturing processes, is crafted to comply with industry accuracy standards, and is tailored to meet your specific application needs. To ensure optimal performance, the plate's bore must be accurately sized and beveled. Our engineering staff can quickly and accurately run your orifice bore calculations for a fee if needed.
USA Industries' universal plates are compatible with standard orifice fitting assemblies or ring-type joint plate holders, making them suitable for use with any dual or single-chambered orifice fittings available. These plates are widely used for measuring differential pressure flow due to their simplicity, reliable performance, easy installation, and resilience to harsh atmospheric conditions.
They are stocked in 304 & 316 stainless steel and can be provided in various materials such as monel, hastelloy, copper, nickel, and more. Additionally, USA Industries can apply coatings based on your specific requirements.
To ensure a proper seal, seal rings are snapped in after installing the orifice plate into the carrier, creating seals on both the upstream side of the plate and the fitting seat.
