Precise control of low flow rates is a critical requirement in many process applications, including those where operating conditions are particularly challenging.

Control Valves Meet the Toughest Challenges

Pump Engineering Ltd., UK

Badger Meter control valves, available from Pump Engineering are an ideal choice. For example, Badger RC200 in AISI 316 stainless steel with stainless steel actuator, is able to withstand the most aggressive environments.

The RC200 valve is designed for handling liquids and gases under the most arduous conditions and is available as a globe or angle pattern in either ¼” or ½” sizes. Its compact size and 33 different trim sizes, Cv range from 0.0000018 to 2.5 and rangeability from 50:1 to 15:1, makes it an ideal choice for additive injection, sampling and pH control.

The valve can operate at pressures up to 5000 psi and temperatures ranging from -80ºC to 500ºC. They can be supplied as standard in 316 stainless steel with stainless steel or Stellite trims, although alternative materials such as Monel, Hastelloy B & C, titanium and zirconium, can also be specified. Standard packing is TFE chevron rings with graphite, while Grafoil or Kevlar are also offered as options.

The RC200 valve can be supplied with pneumatic actuators or positioners, air-to-open (ATO) or air-to-close (ATC) in die cast aluminium, with 316L stainless steel as an option. Electric actuators and positioners can also be supplied if air is not available. Typical applications will occur in snack flavouring, petroleum refining, chemical processing, manufacture of synthetic fuels and lubricants.
