本产品为用于快关工况的液动蝶阀。储能方式、关闭曲线及故障安全动作须根据所选设计确认。如需项目报价,请提供所需通径、压力等级、材质、阀座密封形式、连接方式及数量。最终适用性根据批准的技术规范确认。
产品详情
hydraulic actuation for quick-closing duty, with the energy-storage arrangement and closing characteristics subject to confirmation for the selected design
a shaft rotates the disc through a quarter turn; seat geometry, differential pressure, flow direction, line velocity, cycle frequency, and actuator torque determine shutoff and control performance; verify trip logic and water-hammer limit
turbine inlet protection, pump discharge, hydropower, cooling-water systems, and emergency isolation
accumulator capacity, trip logic, water-hammer limit, fail-safe mode, reset procedure, proof testing, and closing curve
