The EMCO multihole restriction orifice plate are used to restrict the flow in order to prevent damage on pipe line equipment on the upstream side in blowdown systems or to limit the flow/pressure to avoid damage on equipment on the downstream side. For insertion between compact flanges or clamp connection, we can help you with the right technical advice. Type MRP/1 is for RF flanges and type MRP/4 is for RTJ flanges.
