Sanitary Pneumatic Reversing Valve
Applications The divert seat, valve is a kind of hygienicsingle-seat valve pneumatically ,which is applied to a wide range ofapplication in the food-processing industry, beverage production.pharmaceutical and fine chemicals industries.
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).
