Display the internal structure of Ball valves
If you still have no idea of the structure of the ball valve, the following three videos can give you a better understanding of the internal structure of the 1-piece ball valve, the 2-piece ball valve, and the 3-piece ball valve.
Ball Valve of Welflow-Leadtek
Welflow Ball Valve is almost in stainless steel material – SS304 & SS316. And some material in Carbon Steel (ASTM A216 WCB). So we usually have plenty of stock for BSPT Threaded Ball Valve in SS304. Certainly, BSP, NPT also have small stores.
Ball Valve is one type of quarter-turn valve, which is quite literally a ball placed in a passageway through which fluid flows. The ball has a hole through it, by which the valve opens and closes. The ball valve is mainly used in the pipeline to cut off, distribute and change the flow direction of the medium.
A threaded Ball Valve is the type of ball valve with a thread connection.
This design ball valve has body and end connections formed from a single piece of material.
Three different kinds of handle:
- Normal lever handle;
- Lock Lever Handle;
- Wing Butterfly Handle.
Advantage: Total cost is the cheapest compare with other design ball valves.
Disadvantage: When the valves leaks, it couldn’t be repaired, needs to replace directly.
A threaded Ball Valve is the type of ball valve with a thread connection.
This design ball valve consists of two separate pieces, one is the valve bodies, the other is a bonnet(cap).
For 2pc screwed ball valve, the connection between them being either threaded.
Advantage: 1. Between the same quality ball valves, the 2-piece ball valve is relatively more resistant to high pressure.
2. When the valves leaks, it could be repaired by changing the sealing or packing.
Disadvantage: When replacing parts, the valve needs to be removed from the pipeline and connections only in thread or flanges.
A threaded Ball Valve is the type of ball valve with a thread connection. In addition, there are butt-welded ball valves, socket-welded ball valves, and tri-clamp ball valves.
This design ball valve consists of three pieces, one body, and two end caps. Two caps could be the female thread, butt-welded(BW), socket welded (SW), Clamp Ends, Long Butt Welded Ends, Male Thread and flange ends.
And there parts connection with 4 bolts and nuts.
Advantage: 1. Easier disassembly and maintenance than 1-piece and 2-piece
2. More connections for choosing.
Disadvantage: The total cost also the highest compare with the other two design ball valves.
A threaded Ball Valve is the type of ball valve with a thread connection.
This design ball valve is tee through type, the flow of the medium is completely different from straight-through type.
3 Way Ball Valve has two different designs, L type, and T type. The outlooks are the same between these two different valves.
The only difference is of the balls inside the valve bodies. Normally, L type ball valve price is a little higher than T type.
Advantage: It could change the flow direction of the medium.
Disadvantage: The total cost also the highest compare with the other two design ball valves.
This design ball valve with ISO 5211 high mounting pad, could install with a pneumatic or electric actuator directly.They are more suitable for automated equipment. All of upon ball valves have ISO5211 pad design.
Advantage:
1. Fully automatic switch
2. It can also be equipped with a handle, manually operated.
Disadvantage:
1. The total cost is high, need requires supporting actuator.
2. If using the handle, the torque will be higher than other manual ball valves.
Mini Ball Valve lies in the name itself, it is always in mini size from 1/8″ to 1″. It is always with the polished outside surface.
