Answer1:(ambient temperature, fine sand, low concentration corrosion, high wear resistance): Preferred recommendation: Natrite Rubber sleeve. Reason: The core advantage of Natrite Rubber lies in its excellent wet abrasion resistance, particularly suitable for applications with severe wear such as fine sand and powdery materials. Its temperature resistance range (-30°C to +80°C) and corrosion resistance rating (10% acid, 30% alkali) fully meet the requirements of this condition. Selecting Natrite Rubber for this condition achieves the longest service life at a more economical cost.
Answer2: (high temperature, high concentration corrosion): Must select: Hypalon sleeve. Reason:The core challenges of this condition are high temperature (90°C) and high concentration corrosion. The maximum temperature resistance of Hypalon sleeve reaches 130°C, with acid/alkali resistance up to 50%, fully covering and providing margin for the performance requirements, making it the only reliable choice to ensure long-term stable valve operation under these harsh conditions.
For these two significantly different conditions, do you recommend using the same sleeve material or different materials? According to your technical data, which is more suitable between Natrite Rubberand Hypalon?
Summary: Do not standardize the sleeve material. “Natrite for ambient temperature wear resistance, Hypalon for high temperature corrosion resistance”is our core selection principle.
Valves are everywhere in industrial processes—controlling flow, isolating equipment, and protecting systems from overpressure. Yet for many engineers and technicians, the range of options can feel overwhelming. This guide covers the fundamentals of industrial valves, with a closer look at three widely used types: the lined valve, the pinch valve, and the stainless steel ball […]
Valve installation looks simple on paper—until you’re on-site, the flanges don’t line up, and the process fluid is waiting. In reality, poor installation is one of the leading causes of premature valve failure, leakage, and costly downtime. Whether you’re working with a lined valve, a strainer, or a pinch valve, the same fundamental rules apply. […]
