Anti-Erosion Ball Structure: Ensures a larger flow area at the initial opening stage under the same stroke, rapidly reducing pressure differentials and minimizing high-pressure erosion time, effectively extending service life.
Special Condition Adaptation: In specific work conditions (e.g., main steam pipeline drainage valves that also handle steam discharge during pipeline warm-up), high flow velocity and impact force cause high-frequency oscillation of the ball within the valve

  •    Description   

    1. 1/4-Turn Operation: Significantly reduces packing wear and friction, preventing external leakage.

    2. Anti-Erosion Ball Structure: Ensures a larger flow area at the initial opening stage under the same stroke, rapidly reducing pressure differentials and minimizing high-pressure erosion time, effectively extending service life.

    3. Graphite Packing and Seat Pre-Tightening: Utilizes disc spring pre-tightening to prevent seizing under high temperatures.

    4. Special Condition Adaptation: In specific work conditions (e.g., main steam pipeline drainage valves that also handle steam discharge during pipeline warm-up), high flow velocity and impact force cause high-frequency oscillation of the ball within the valve cavity, impacting the stem and sharply increasing torque. This may lead to stem breakage or distortion, rendering the valve inoperable. Throttling orifice plates are used to dissipate energy during initial valve opening, minimizing erosion and cavitation.

    5. Integral Design: Compact and Small&Beatiful structure.
