Prevents media from flowing backward when the medium stops flowing

- May 29, 2018 -

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 the swing check valve, and the flow of the swing check valve is limited Very little. Check valves are generally suitable for clean media and should not be used for media containing solid particles and high viscosity.

Forged steel check valve clapper upper and bonnet lower processing guide sleeve Jane, the valve guide Jane can freely lift in the valve cymbal guide Jane, when the media downstream, the valve is opened by the media thrust, when the media stop flow The valve flap lands on the valve seat by self-sagging and acts as a counteract to the counter flow of the medium. The straight-through butterfly check valve medium inlet and outlet channel direction is perpendicular to the seat channel direction; the vertical lift check valve has the same medium inlet and outlet channel direction and the seat channel direction, and its flow resistance is smaller than the straight-through formula.
