High Pressure Angle Type Control Valve ANSI 2500 Venturi Type Forged Angle Valve

VAH High-Pressure Angle Control Valve

The valve core and valve seat of the VAH high-pressure angle control valve are made of materials with extremely high hardness to prevent erosion and wear caused by high-pressure fluids. The fluid flows from the side to the bottom; for controlling gas, the flow direction can also be from the bottom to the side.
