INOXPA Shut-off Seat Valve N/M
The N/M shut-off valve is a hygienic single seat pneumatically operated valve with a wide range of applications in the food-processing, pharmaceutical and fine chemicals industries.
Product Description
Application
Operating principle
Seat valves are automatically operated by a single-acting or a double-acting actuator. Compressed air moves the shaft to place the valve in the “open” or “closed” position. The 180º rotation of the pneumatic cylinder of the 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.
- Weld connections (mm or inches).
- Available sizes: from DN 25/1″ to DN 100/4″.
- Easy disassembly of internal parts by loosening the clamp fastener.
- Open lantern to allow visual inspection of shaft sealing.
- 360º adjustable body
