ORBINOX RA model tilting disc check valve is an ideal solution to protect reverse flow situations in pressurized piping systems and on the pump pressure side in a wide range of media such as raw water, wastewater, drinking water, cooling water or industrial water with solid content. Reverse flows are usually produced by system shutdowns situations or surge conditions as a result of emergency operations that can cause severe damage to equipment installed in the piping systems or even the piping systems themselves. ORBINOX RA check valves are conceived to prevent these consequences.
 
ORBINOX RA check valves are double-eccentric wafer or flanged valves, both with cast body or fabricated body construction in sizes up to DN 2000 and for applications up to 25 bar. Our valves are designed for horizontal piping and vertical piping installations.

  • Reverse flow situation when pumps shut downs and surge tanks with elevated waterheads and variable flow rates require a rapid closing cycle time to prevent damage in the pumps

  • The disc is formed by a main deep circular disc manufactured both in carbon steel WCB 216 A and also fabricated in S275JR carbon steel or in different stainless steel grades, from AISI 304 and AISI 316 to, depending on the application

  • The shafts are solid stainless steel AISI 630 and rotate on self- lubricating bronze bearings. The shafts are attached to the disc by keyway

  • A counterweight assembly composed of S275JR carbon steel plates is attached to the valve shaft. The weight or number of plates are calculated based on the required closing time and service conditions.

  • Composed of a hydraulic cylinder usually in S275JR carbon steel and an hard-chromed AISI 304 stainless steel stem, with both ports connected to a S275JR carbon steel oil tank, in a closed circuit
