Can a non-return valve be installed vertically?
They can also be installed in any position: vertical, horizontal or oblique.
Can you put a check valve in the vertical?
Check valve can be installed in horizontal or vertical piping runs, with the flow running upward.
Which kind of valve Cannot be installed in vertical lines?
Why Swing Check Valves Don’t Work in Vertical Pipe Runs. If the flow in the vertical line is going upwards (against gravity), gravity will cause the disc to slam against the seat when the flow stops or a pump shuts down, leading to potentially severe water hammer.
Can a swing check valve be installed in any position?
Swing check valves can be mounted in either vertical or horizontal position with upward flow or in any intermediate position. Flow must be by direction of arrow in body.
Can a check valve be installed upside down?
The compromise is that the valve can be installed in other orientations. Installation upside down is not recommended because of the possibility of dirt build-up in the bonnet.

What is the difference between non-return valve and check valve?
A non-return valve lets the fluid flow in one direction. When fluid in the line reverses direction, a check valve prevents backflow by allowing flow in one direction. The check valves are usually designed for a particular pressure.
What is a vertical check valve?
The H-700 Vertical Check Valve is designed for vertical flow (not suitable for down-flow applications). The disc shaft is fully guided to insure proper alignment between disc and seat. The disc and seat are accurately machined for precise seating. An optional resilient seat is available for drip tight shut-off.
