371 and 771 Series Throttling Valves
For more precise control of the process
For Regulating Pressure and Product Flow
Alfa Laval offers a comprehensive line of valves for applications which require
precise control of product flow, pressure and temperature, in order to preserve product integrity.
371 and 771 Series Air-Operated Regulating Valve
The design of this valve is based on our 300 and 700 Series lines. However, it features a wide selection of stainless steel tapered valve stems and special actuators that deliver an outstanding degree of product control.
In fact, the tapered design results in product flow which is in direct linear response to stem movement.
Stem choices are available with varying degrees of taper to correspond with the needs of your application.
Valve positioners help achieve this control. They provide a stabilizing action in a valve’s pneumatic circuit. Plus, they are engineered to maintain a predetermined valve position, regardless of other forces acting on the valve to change that position. |
