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.
Quick Pressure Relief Valves protect pumps and water distribution systems from extreme situations by relieving the excessive pressure immediately.
It opens fully in case of a sudden pressure peak and closes drip tight when the pressure level does not exceed the pre-set pressure level.
Solenoid Control Valves are simple electrically activated on/off valves that can be of critical importance in controlling flow in every water system.
The electrical signal used to activate the solenoid can be sent from timers, relays, clocks, pressure, level or flow transmitters, etc.
