INOXPA Shut-off Seat Valve N/M

Application

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.

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
