Flange type dual check valve, wafer flange check valve, duo check valve, dual disc check valve,600LB Dual Plate Flange Type Check Valve
Because the check valve flange type doesn’t tapping on the flange hole, installation of double door flange type check valve is simpler than double door lug type check valve
STV valve is an ISO 9001 accredited and CE certified manufacturer of Dual Plate Check Valves with design features as per API 594 Standards
Double door flange type check valves we have standard retainerless design too.
We take our commitment to product quality and documentation seriously. We provide only the best to our customers.
Double flanged Type are offered as standard on larger size valves where the lay length of the body permits installation of two nuts between the flanges.
Flange type valves are provided with thru-hole bolting in accordance with API 594.
A check valve relies on a pressure differential to work. They require a higher pressure on the input side of the valve than the output side to open the valve. When the pressure is higher on the outlet side (or the input side pressure is not high enough), the valve will close. Depending on the valve type, the closure mechanism is different. Unlike other valves, they do not need a handle, lever, actuator, or human to correctly work.

More Knowledge about flange type check valve valve:
The flange surface of the flange type check valve has an outwardly extending flange and screw hole, but there is no tapping; the installation is more convenient than the wafer type. The flange type of STV not only saves space because the installation is to add a bolt and two nuts to each flange hole, which is less likely to move after installation, so, flanged check valves are also particularly suitable for use in vibration-prone work environments or the country where located in seismic belts.
More Knowledge about dual plate check valve:
Double flanged Type are offered as standard on larger size valves where the lay length of the body permits installation of two nuts between the flanges. Flange type check valve is installed between two flanges using a separate set of bolts for each flange. This setup permits either side of the piping system to be disconnected without disturbing the other side. Flange Type Check Valve with two discs permits installation in a piping system in same manner as any conventional double flanged valve, i.e. studs and nuts per flange; this is one of the easiest connections to be installed or uninstalled from a pipeline. As Double flanged Type Check Valves are fastened to the pipe flanges, assembling or disassembling them is quick and easy. An important point to be mentioned about Double Flange types of end connections is that they are secured with several bolts. Flanged connections are the most common method of connecting valves, regardless of the pressure level (from low to high pressure levels) and valve size (from small to large valves). Flange dual plate check valves work automatically and it is not controlled by a person or any external control. Double flanged Type is offered as standard on larger size valves where the lay length of the body permits installation of two nuts between the flanges. Flange type valves are provided with thru-hole bolting in accordance with API 594, and if you have another standard demand, please send the inquiry to us.
