Design and manufacturing techniques of the Ramén Ball Sector Valve are based on long and diversified use in demanding applications and environments. The Ramén Ball Sector Valve has proved to be advantageous for tight shut-off and throttling control of gases, liquids and slurry in moderate pressure and temperature conditions.

The Ramén Ball Sector Valve was launched in 1967 and since then many thousands of valves have been installed in: Pulp & paper industry Mineral ore processing Wastewater and water treatment plants Gas handling & production Chemical industry Cement industry Steel works The Ball Sector Valve is generally used instead of other control valves because of its: High flow capacity Accurate flow control Capability of throttling paper stock and other slurries Superior resistance to abrasion Economy in weight, size and price Availability in a wide range of sizes from Kvs=0,25 to 5980

Materials & size range: Stainless steel: DN25-400 (1"- 16"), PN16(25) Titanium: DN25-150 (1"-6") PN16 Rubber lined ductile iron: DN80-200 (3"- 8") PN10 used for abrasive, non-corrosive, liquids, max 5 Bar, 50°C.

Construction principle Ramén Ball Sector Valve is made from a half ball - a ball sector - which via two shafts is supported in the valve body. One part of the ball sector sphere is used for shut-off. The other part of the sphere has a hole with a diameter of about 80% of the nominal valve size. The ball sector is turned through 90° from open to fully closed. The shape of the valve opening during operation thereby changes from fully round to narrow elliptic. The almost round shape of the throttling orifice reduces the risk of plugging and is less subject to wear in the throttling position than the more slot-like flow opening in many other types of valves.
