MKS Instruments 248A / B / C Flow Control Valves

Features
  • Modulates Gas Flow to Maintain Accurate, Precise Pressure
  • Spiral Springs Minimize Friction and Hysteresis
  • Orifice Can Be Adjusted or Replaced without Special Tools

Description

The MKS 248A / B/ C Flow Control Valves are a modified solenoid valve that, when supplied with a controlling current, are able to modulate the flow of gas. When used with a MKS controller and appropriate flow sensor, the 248 valve modulates gas flow so that pressure or flow is maintained accurately and with precision. The valve seat connected to the armature is lifted away from the adjustable orifice as increasing current is applied to the solenoid. Two spiral springs center the armature within the valve body and oppose the magnetic lifting force. These springs minimize friction and hysteresis which are the major causes of poor control performance.

An important feature of the 248 valve is its orifice which may be adjusted or replaced without special tools. Adjustment may be required to eliminate leakage across the valve resulting from normal operational wear.
