Rowlyn Special Gr.2 Vertical lift titanium check valve

Product description:

Titanium lift check valve:

Check valves that slide along the vertical center line of the body, internal threaded check valves can only be installed in horizontal piping, and disc can be rounded on high pressure small-bore check valves.Butterfly check valves have the same body shape as globe valves (can be used with globe valves), so it has a higher fluid resistance coefficient.It is similar in construction to globe valves and has the same body and disc as globe valves.The upper part of the disc and the lower part of the bonnet are processed with guide sleeve, the guide disc can be lifted and lowered freely in the valve holder guide, when the medium is downstream, the disc is opened by the medium thrust, when the medium stops the flow, the disc is landing on the seat by itself, preventing the medium from reverse-flow.Straight butterfly check valve medium inlet and outlet channel direction and valve seat channel direction vertical;Vertical lift check valve, the direction of the medium inlet and outlet channel is the same as the direction of the valve seat channel, its flow resistance is smaller than the straight type.
