Detail

Welded gate valves control the opening and closing of the valve by lifting and lowering the gate plate.The gate plate is perpendicular to the fluid direction,and changing the relative position between the gate plate and the valve seat can change the channel size.The fluid resistance is low,and the sealing surface is less susceptible to the friction and erosion of the medium.Opening and closing is more effortless.The flow direction of the medium is unrestricted,without disturbance or pressure reduction.Simple form,short structural length,good manufacturing processability,and wide applicability.
