Needle Plunger Valve

Needle Valves open and close by the axial movement of the disc that is connected to a crank and shaft mechanism which the gearbox commands. 

When the valve is in fully open position, due to its aerodynamic design, it causes very low head loss and maximum flow capacity.

The disc is guided by circular disc guides deposit welded to the main body, which causes minimum friction loss and stable movement.

Stem, rotated by the gearbox, commands the crank mechanism which moves the disc axially to change the opening area of the valve.

When the valve is in fully closed position, due to special sealing mechanism, drip tight sealing is achieved.

Due to pressure-independent disc operation and special gearbox, torque values needed even in large sizes are minimum.
