Universal and Paddle Type Orifice Plates, RTJ Restriction Plates, Restriction Orifice Unions

We manufacture our Series 500 Universal Orifice Plates, Series 520 Paddle Type Plates, Series 560 and 590 Ring Type Joint (RTJ) Holder Plates and Restriction Orifice Unions to meet or exceed standards set by A.G.A., I.S.A., A.N.S.I., A.S.M.E. and A.P.I. recommendations. We stock plates in 304 & 316 stainless steels and in 1/8" and 1/4" thicknesses. If you need your orifice plates manufactured in other materials and/or thicknesses, just let us know. We most typically bore the plates to the customer's supplied sizing calculations; however, we have a team of professional mechanical engineers on staff that will provide bore sizing calculation services to you for an additional fee.
