　　Chemtrol塑料隔膜阀具有理想的防腐或高纯度化学物质和水，研磨性泥浆，以及真空应用等特性。这些多旋转阀门适用于精确流量控制，突出的经久耐用，以及防泄漏操作。没有滞流的空穴或缝隙，加上利用流经阀门的无堵塞流体的自动清洗，使得这些阀门成为泥浆，容易附着在表面的盐类，以及对微生物生长敏感的应用领域。
　　Chemtrol plastic Diaphragm Valves offer characteristics ideal for corrosive or high-purity chemicals and water, abrasive slurries, and vacuum applications. These multi-turn valves are designed for accurate flow control, outstanding durability, and leak-proof operation. The absence of stagnation pockets or crevices, together with the self-cleansing of unobstructed flow through the valves, make them ideal for slurries, salts which tend to plate-out on surfaces, and services which are sensitive to microbiological growth.

特点
Features

• 隔膜将阀门的工作部件与所处理的流体介质隔离开来，延长了使用寿命，改善了防泄漏性能。
  Diaphragm isolates the working parts of the valve from process medium for long life and leak-proof performance.
• 无填料设计将外壳泄漏的可能性降到最小程度，特别适用于排放控制应用领域。
  Pack-less design minimizes the potential of shell leakage for ideal emissions control.
• 弹性隔膜确保流体的气密性关闭。
  The resilient diaphragm assures bubble-tight closure to flow.
• 没有空穴或死角，因此避免了累积，所处理的流体的滞流，或污染。
  No pockets or dead spaces, thus preventing accumulation or stagnation of process fluids or contaminants.
• 多旋转操作使得手动阀门能够进行精确节流。
  Multi-turn operation allows for precise throttling of manual valves.
• 可视位置指示器是标准配置。
  A visual position indicator is standard.
• 三元乙丙橡胶或聚四氟乙烯隔膜选项使得应用更加广泛，从防腐，到泥浆和高纯度。
  EPDM or PTFE diaphragm selection affords wide range of applications, from corrosives to slurries and high-purity.
• 固定器/支架螺栓孔位于阀门的基座。
  Anchor/support bolt holes are located in base of body.
