QSL1T-3 Reducing Bore 1PC Ball Valve

The ball core of a one-piece ball valve should be inserted from the threaded end of the valve body. If the diameter of the ball core runner is processed to the same value as the nominal diameter, the outer circle diameter of the ball core should be larger than the outer circle of the reduced diameter ball core. As a result, the ball core cannot be inserted into the valve body from the valve body thread, because the diameter of the outer circle of the sphere exceeds the inner hole size of the valve thread.


For the one-piece internal threaded ball valve, due to the size limitation of the valve body structure, the full bore ball core cannot complete the assembly of the ball core. Not loaded into the valve body. Therefore, the core can only be used in the form of reduced diameter.

QSL1T-3 Reducing Bore 1PC Ball Valve FAQs

Q What Is The Difference Between The Full Bore Ball Valves And Reducing Bore Ball Valves?
A.

The biggest difference between full bore ball valves and reducing bore ball valves is that the full bore ball valve has a constant-width flow passage. Its size cannot be less than the value specified by the standard, which is roughly equivalent to the nominal diameter of the specification. The inlet of the reducing bore ball valve is wider than the diameter of the flow path and the actual diameter of the flow path is smaller. For example, the flow passage diameter of the DN50 reducing bore ball valve is about 38mm, which is roughly equivalent to the specifications of DN40.

Q What Connections Of Our Ball Valve Are Available?
A.

flanged, thread, socket welding, butt welding
