Brass Check Valve

The purpose of this type of valve is to allow the medium to flow in one direction only and to prevent the medium from flowing in the opposite direction. This type of valve usually works automatically. Under the pressure of fluid flow in one direction, the valve flap opens. When the fluid flows in the opposite direction. The fluid pressure and the self-weight of the valve flap acts on the valve seat, thus cutting off the flow.

How Brass Check Valve Work

One such valve is the check valve, which includes swing check valves and lift check valves. Swing check valves have a hinge mechanism and a gated valve flap. Which is free to rest against an inclined seat surface. To ensure that the valve flap reaches the proper position on the seat surface every time. The valve flap is designed in the hinge mechanism so that there is enough room for the valve flap to swing and so that the valve flap makes true. Full contact with the seat.

Depending on performance requirements, the valve flap can be made entirely of metal or inlaid with leather, rubber or synthetic materials. In the fully open state of a swing check valve. Fluid pressure is virtually unimpeded. So the pressure drop across the valve is relatively small. The flap of a swing check valve is located on the sealing surface of the seat on the valve body.

In addition to the valve flap can be free to lift, the rest of the valve is similar to the globe valve. Fluid pressure lifts the valve flap from the sealing surface of the valve seat. And the return flow of the medium causes the valve flap to fall back to the valve seat and cut off the fluid.

According to the conditions of use, the valve can be all-metal structure, can also be embedded in the valve seat of the rubber gasket or rubber ring form. Like the globe valve, lift check valve fluid passage is also very narrow. So the pressure drop through the lift check valve than through the swing check valve pressure drop is larger. The flow rate of the swing check valve is also subject to rare restrictions.
