Operating principle Seatvalves are operated automatically by a single-acting or a double-actingpneumatic actuator. By supplying compressed air,the shaft is moved to place the valve in the "open" or”closed”position. The180°rotation of the pneumatic cylinder of single-actingactuators allows to have a normally open or normally closed valve. Design and features Compact androbust design. 3A certified valve. Availablesizes: from DN 25/1" to DN 100/4". Normally closed valve (NC) in the standard version. Thevalve can be changed to normally open (NO) by simply reversing the position ofthe pneumatic actuator. Hygienicdesign according to 3A standards. 360°adjustable body. Openlantern allows visual inspection of shaft sealing. Easy assembly/disassembly of internal parts byloosening a clamp fastener. Standardweld connections (mm or inches).
