Restriction Orifice Unions

Restriction Orifice Unions are common in industries such as oil and gas, chemical processing, and power generation, where precise flow control and pressure management are essential. They feature one-piece stainless steel orifice plates shaped to match the union seat (ball to cone), eliminating the need for gaskets. The plates can be configured as recessed, pressed, or pressed with a tab, allowing easy identification of the orifice size without disassembling the union.
