MstnLand's series of forged steel check valve can automatically prevent fluid flow back, check valve disc in the fluid pressure under the action of open, fluid flow from the inlet side to the outlet measurement. When the inlet side pressure is lower than the outlet measured, the valve disc in the fluid pressure difference, its own gravity and other factors under the action of automatic closure to prevent fluid flow back .
