There are many types of pvc ball valves, here is the manual ball valve of PVC, which is also called engineering ball valve. Its design advantages are as follows:
The heavy-duty extra-large diameter shaft is reinforced with additional resin, eliminating the possibility of stem breakage.
Double shaft O-ring.
PTFE bearings eliminate friction and wear.
The PTFE valve seat with O-ring reduces the wear and tear of repeated cycles.
Trunnion design: upper and lower supports can hold the ball under pressure. The trunnion design allows multi-directional flow, so there is no danger of the valve being installed "backwards".
Concentrically machined and mirror polished balls.
The dual sliding seats use triple O-rings to achieve balance and maximum leakage prevention.
The smooth flow path eliminates pressure loss.
The end of the real union facilitates pipe installation and disassembly.
