ORIFICE PLATES

Our innovative Orifice Plate line includes a complete selection of solid PTFE, Tuf-Steel, or a 316L Stainless Steel Orifice Plate molded to a Rubber Fab elastomer, in standard, tabbed, and vertical Tri-Clamp styles, that can be custom drilled with an eccentric or concentric bore. Our tabbed style can be engraved to show important information for installation and process.

Steam trap mini orifice plates are an alternative to standard steam trap technology.

  • Eccentric and Concentric drilled plates
  • Self Draining
  • Engraved Tabs available
  • 20 RA or better for Standard Polish
  • 15RA or better for Electropolished finish
  • Custom cut patterns available

A major safety consideration! Rubber Fab's orifice plates can advance your systems performance, adjust flow rates, balance backflow and equalize back pressure during SIP procedures. Achievable benefits while maintaining sanitary conditions.

Tabs help to acknowledge that an orifice plate is "in line" and can be laser engraved to indicate the hole diameter, gasket size or user specified information.  This Tabbed design of sanitary orifice plate, when coupled with Rubber Fab's slotted clamp, allows the operator complete flexibility when balancing a sanitary pipeline system.

"Thanks again for reacting so quickly and meeting me halfway with the element. We will be able to get installed and have things keep moving overnight with the night crew. The little things like this are always greatly appreciated when working with Liquidyne."

Testimonial from VP Antibody Manufacturing

“This pump cut our processing time from 3 days to 1 shift. I’m not giving this pump back. You will have to come and get it if you want it... and that won’t likely happen.”
