100mm Underground Type Gate Valve For Fire Fighting

Underground valves provide effective management of distribution networks for gas, steam, or drinking water. The majority of underground valves are flow control mechanisms that are crucial to any plumbing system. The flow rates of gases such as liquid petroleum, oxygen, and natural gas are handled, regulated, and controlled by them in the oil and gas business. After the bottom valve is connected to the pipeline, the liquid medium enters the valve body from the direction of the valve cover. The liquid pressure acts on the disc to open the disc and allow the medium to flow. When the medium pressure in the valve body changes or disappears, the disc closes to prevent the medium from flowing backward.

Bottom valve structure: the bottom valve has multiple water inlets on the bonnet and a filter screen to reduce the inflow of foreign matter and the probability of blockage of the bottom valve. Although the bottom valve is equipped with an anti-clogging filter screen, the bottom valve is generally suitable for cleaning media, not for media with excessive viscosity and particles.
