Cast steel electric flange ball valve Q941PPL-16C

Electric flange ball valveIt is a kind of 90°rotation classball valveThe valve has excellent sealing performance, large flow capacity, small flow resistance coefficient, simple structure, easy maintenance, long service life and other characteristics. Its valve body channel and connecting pipe diameter is equal and into a diameter, the medium can flow through almost no loss, with electric actuators, the product is usually used for sealing the strict requirements of the occasion, in addition to the control of gases, liquids, steam media, but also suitable for controlling water containing fiber impurities in the medium. Widely used in petroleum, chemical industry, metallurgy, light industry, papermaking, power station, refrigeration and other fields of work.

产品特性

• 流体阻力小，球阀是所有阀类中流体阻力较小的一种。即使是Reducing Ball ValveThe fluid resistance is also quite low.

• 止推轴轴承减小阀杆摩擦力矩，可使阀杆长期操作平衡灵活。

• 阀座密封性能好，采用PPL对位聚苯酚等材料制成的密封圈，可耐200℃高温，结构易于密封。

• 阀杆密封可靠，由于阀杆只作旋转运动而不做升降运动，阀杆的填料密封不易破坏，且密封能力随介质的压力增设而增大。

• 由于PPL对位聚苯酚等材料具有良好的自润滑性，与球体的摩擦损失小，球阀的使用寿命更长。

• 下装式阀杆和阀杆头部凸阶防止阀杆喷出，如火灾造成阀杆密封破坏，凸阶与阀体间还可形成金属接触，确保阀杆密封。
