4 inch aluminum alloy pneumatic tanker emergency shut off bottom valve

Tanker bottom valve, also known as emergency shut-off valve, is installed at the bottom of the tanker. It is suitable for downloading, refueling, and unloading oil.

The tanker bottom valve is easy to operate, time-saving, safe and environmentally friendly. The bottom valve has a small internal pressure, a large flow rate, and a thorough cutout groove on the flange side of the valve body. In the event of an accident on the tanker, due to the inability to withstand excessive pressure impulse at the cutout, the vehicle body pipeline and the tank will automatically disconnect, while the automatic centering plunger and durable spring will still remain sealed, and the medium in the tank will not leak, thereby ensuring the safety of the tanker.

When there is no air source or other reasons why it cannot be opened, the cylinder piston screw can be disassembled and manually opened.
