Datasheet Butterfly valve for oil and gas applications Type MTV Type MTVG Type MTVL Nominal pressure Nominal size triple • Advanceddesign eccentric manual • Designed foroperated and remote applications Tightness class in accordance with EN 60534-4 Class V as standard • Solid seat made or of stainless steel a soft seat in PTFE with a backup seat in nickel alloy Wafer design Wafer design with guiding lugs Lugged design PN10 - 25 Class 150 DN80 - 500 CF8M (316) 6Mo 22 Cr Duplex 25 Cr Duplex Titanium SOMAS butterfly valve, type MTV is designed for manual and remote operations. This valve is designed to handle a wide range of liquids and gases within a broad temperature range. The MTV valve can be supplied in wafer design, in lugged design (MTVL),and in wafer design with 4 guiding lugs (MTVG). The valve has an advanced triple eccentric design including an unique shape of the disc which enables the use of a solid stainless steel seat as well as a soft seat. The solid seat remains unaffected by high flow velocities and temperatures. A good valve function is achieved even on difficult applications. The SOMAS valves are delivered ready for installation and operation. The manual valves are delivered with levers or gear units and the remote operated valves can be delivered with hydraulic or pneumatic actuators on req
