The N/M valve is single-seat shut-off valvehygienic design with a wide range of applications in the food and pharmaceutical industries.
The principle of operation
Single seat valves they are powered by single- or double-acting pneumatic actuators. Compressed air actuates the stem, and the valve takes the "open" or "closed" position.
In the case of a single-acting actuator, turning the cylinder 180 ° C allows you to change the configuration of the valve - normally open or normally closed.
Design and characteristics
Robust and compact design.
The valve is normally closed (NC) in the standard version.
The valve is normally open (NO) by simply turning the pneumatic actuator.
Standard welding connections (mm or inches).
Sizes: DN 25/1" to DN 100/4".
Dismantling of internal parts by simply loosening the clamp clamp.
The open housing allows for visual inspection of the stem seal.
