球阀阀座材料
Ball Valve Seat Materials

美国尼必可有限公司

纯TFE
Virgin TFE

  纯TFE是一种很好的、多用途、通用的阀座材料。TFE具有显著的耐多种化学腐蚀的性能,包括有机化学材料,无机化学材料和多种溶剂,通常被认为是化学惰性物质。TFE是一种自润滑聚合物,摩擦系数很低,这使得TFE成为角行程球阀极好的阀座材料。
  Virgin TFE is a good all-around, general purpose seating material. TFE has outstanding resistance to chemical attack by a broad spectrum of organic chemicals, inorganic chemicals and solvents and is generally considered chemically inert. TFE is a selflubricating polymer with a very low coefficient of friction, which makes an excellent seating material for quarter-turn ball valves.

色标
Color Code

纯TFE树脂具有天然的白色色素。
Virgin TFE resin has a natural pigment of WHITE.

温度范围
Temperature Range

在球阀应用中,温度范围为-28oC至204oC

15%强化TFE
15% Reinforced TFE

  在美国尼必可中档球阀产品中,采用短束玻璃纤维作为强化材料。增加强化材料能够增加TFE的压力包容能力,降低冷变形倾向。
  NIBCO uses short strand fiberglass as a reinforcement for our mid-range ball valve products. Adding reinforcement increases the pressure containing capabilities of TFE by reducing its tendency to cold-flow.

色码
Color Code

15%加强TFE的色标为蓝色。这种色素永久性融合在TFE聚合母体内。
15% reinforced TFE is color coded BLUE. This pigment is permanently molded into the TFE polymer matrix.

温度范围
Temperature Range

在球阀应用中,温度范围为-28oC至204oC
-20oF to +400oF temperature range in ball valve applications.

压力范围
Pressure Range

27"真空至1,000 PSI非冲击性水,油或气
27" vacuum to 1,000 PSI non-shock water, oil or gas.

特征
Unique Features

比纯TFE具有更好的抗冷变形能力。
