Magna™™ Flow Control Valve
Series 608 & 700
For Gases or Liquids
1100 Precise Setpoints
The Magna Flow Control Valve with an easy to read micrometer dial offers an amazing 1100 precise set points to accuray control flow of gases or liquids. The extremely high CV of the Magna Flow Control Valve enables very high flows with the Series 608 and lower flows with the Series 700 for whatever media is being controlled, up to 200 PSIG pressure or full vacuum. Linear flow characteristics provide easy to set and precise metering of gases and liquids for almost any application where accurate results are required.
Hundreds of Applications
Available in light-weight impact resistant nylon, the Magna Flow Control Valve offers superior strength and corrosion resistance, making it ideal for use in hundreds of different applications. Simplicity of construction, with removable top and bottom caps, provides easy disassembly for cleaning or maintenance without removing the valve from service. Proven O-ring seals provide a positive zero leak shut-off. Replacement of seals, if required, is quick and easy because disassembly is simple and fast. The Magna Flow Control Valve offers all these features at a very affordable price.

   Posi-flate 蝶阀*的设计， 采用气体压力使阀座向着阀盘伸展， 以便于随时为密封提供均匀分布的压力。 由于在阀门的开启和关闭期间， 阀盘和阀座只会发生瞬时接触， 从而使阀盘仅受到轻微的碰撞。 相反，对于一般的蝶阀来说，阀盘擦过阀座产生的碰撞，会降低阀门的性能和寿命。
实际上，打开和关闭Posi-flate蝶阀时只需要很小的扭矩。 这样可以使用较小的执行器，从而降低整个阀门的成本。
