Restriction Unions
Restriction unions come in stainless steel and carbon steel bodies with a T-316
cup-type or tab-type plate that sits in the middle. Each side of the union is threaded together to seal the restriction plate.
Restriction unions are generally used in 2" and under nominal pipe sizes. EBG can sell both the union and the plate together as a whole or just the replacement
bored or blank plate.

Restriction Unions are used for flow restriction purposes and are available in 2" line sizes and below. Unions are available in threaded or socket weld (both shown herein)
Each union is furnished with one T-316 stainless steel orifice plate (bored or blank)
