    Product Description

    1. High Pressure Differential Labyrinth Control Valve adopts multi-stage throttling structure with labyrinth discs. Multi-layer labyrinth pressure reduction components are built in cage.

    2. Medium consumes pressure step by step through labyrinth passages to reduce flow velocity and resist cavitation and erosion.

    3. Hard alloy overlay on plug and seat resists wear under high differential pressure.

    4. Used for high differential pressure process medium regulation in power and chemical industry.

    Features & Benefits

    1. Multi-stage labyrinth pressure drop suppresses cavitation.

    2. Greatly reduce medium velocity and lower erosion.

    3. Hard alloy sealing surface for wear resistance.

    4. Stable regulation under high differential pressure.

    5. Suitable for severe services in power and chemical industry.
