The divert seat valve is a hygienic single seat pneumatically operated valve with a wide range of applications in the pharmaceutical industry.
Operating principle
Seat valves are operated automatically by a single-acting or a double-acting pneumatic actuator. By supplying compressed air, the shaft is moved to place the valve in the "open" or "closed" position.
The 180º rotation of the pneumatic cylinder of single-acting actuators allows to have a normally open or normally closed valve.
Design and features
Compact and robust design.
Normally closed valve (NC) in the standard version.
The valve can be changed to normally open (NO) by simply reversing
the position of the pneumatic actuator.
