5697High Pressure Angle Single-Seated Control Valve
Brief Description

Type 5697 High Pressure Angle Single-Seated Control Valve is a kind of top guiding control valve. Less pressure drop loss, large flow rate, wide adjustable range. Guiding area of valve disc guiding is big, and good vibration resistance, equipped with spring diaphragm or piston cylinder actuators, which is compact structure, and big output force.
