๐Ÿ’ง Hydraulic Valve โ€“ Hydraulic Power for Demanding Services

๐Ÿ”น High output torque โ€“ Hydraulic drive delivers far greater torque than pneumatic or electric actuators โ€“ easily handles large-diameter valves

๐Ÿ”น Explosion-proof, spark-free โ€“ No electrical power required, eliminates spark risks โ€“ ideal for oil & gas, chemical, and other hazardous environments

๐Ÿ”น Remote control, unattended operation โ€“ PLC intelligent control system supports local, remote, and interlocked control โ€“ integrates with SCADA/DCS

๐Ÿ”น Emergency backup โ€“ In case of power failure, accumulators provide one or more open/close cycles โ€“ reliable emergency shutdown for long-distance pipelines

๐Ÿ”น Precise & adjustable โ€“ Opening/closing torque precisely adjustable via pressure relief valves; speed easily regulated

๐Ÿ’ช Large Diameter Cast Steel Ball Valve Pressure Test โ€“ Every Valve Proved Under Pressure

Large diameter, high flow โ€“ and even higher reliability. Every cast steel ball valve must pass rigorous pressure testing before leaving our factory:

๐Ÿ”น Fully automatic hydrotest equipment โ€“ Specialized for large diameters up to DN1200; uniform clamping force eliminates human error
๐Ÿ”น Shell strength test โ€“ 1.5 x rated pressure, adequate hold time; no leakage or deformation on body or any pressure-containing parts
๐Ÿ”น High-pressure gas seal test โ€“ 1.1 x rated pressure with high-sensitivity leak detection; bi-directional zero leakage required for release
๐Ÿ”น Seat seal verification โ€“ Double-piston-effect seats tested under both low & high pressure to ensure tight shutoff under pressure fluctuations
