Z41F 衬氟闸阀主要特点 1. 耐腐蚀性强：阀体、闸板、阀杆等与介质接触的表面衬有FEP(F46)、PCTFE(F3)等氟塑料，适用于各种强腐蚀性介质。 2. 密封可靠：密封副通常为FEP/FEP或其他低摩擦材料组合。填料常采用PTFE，密封性好且更换方便。 3. 双向流动：介质可从阀门两侧任意方向通过，适用于介质流向可能改变的管路。 4. 弹性闸板：一些型号采用弹性闸板，能自动补偿密封面的楔角偏差，密封效果更好。 5. 不用于节流：楔式闸阀不允许微量开启用作节流，以免高速介质冲蚀损坏密封面。 Main Features:  1. Excellent Corrosion Resistance: Components like body, gate,  stem in contact with the medium are lined with FEP(F46), PCTFE(F3), etc., suitable for various highly corrosive media。 2. Reliable Sealing: The sealing pair often uses FEP/FEP  other low-friction combinations. Packing typically uses PTFE for good sealing  easy maintenance。 3. Bidirectional Flow: Medium can pass through the valve  either side, suitable for pipelines  flow direction might change。 4. Flexible Gate: Some models use a flexible gate to automatically compensate for wedge angle deviations, ensuring better sealing。 5.  for Throttling: Should  be partially opened for throttling to prevent erosion of sealing surfaces by high-velocity medium。
