What medium is suitable for forged steel check valves?

The passage of the forged steel check valve fluid through the lift check valve is also narrow, so the pressure drop through the lift check valve is larger than that of the swing check valve, and the flow rate of the swing check valve is limited. Very few. Check valves are generally suitable for cleaning media and should not be used for media containing solid particles and high viscosity.

The upper part of the valve block of the forged steel check valve and the lower part of the valve cover are machined with a guide sleeve, and the valve guide can be easily lifted and lowered in the valve guide. When the medium is downstream, the valve flap is opened by the medium thrust, when the medium stops flowing. The valve flap descends from the sag on the valve seat to prevent the medium from flowing backward. The direction of the inlet and outlet passages of the straight-through butterfly check valve is perpendicular to the direction of the valve seat passage; the vertical lift check valve has the same direction of the medium inlet and outlet passages as the valve seat passage, and its flow resistance is smaller than that of the straight-through type.
