Valtek Mark 200 High Pressure Control Valve
The Mark 200 high pressure globe control valve designed to handle the most extreme severe service applications also offers high competitive fl ow
capacity. The Mark 200’s large galleries include longer stroke lengths which provide fi ner control and result in more stages of severe service protection
in smaller size valves. With a clamped-in (DIN, screwed-in) seat ring, the Mark 200 has been designed for easy maintenance and fl exibility. The seat
retainer/cage (DIN, seat ring) in the Mark 200 can be changed out to provide an exceptional variety of severe service options, including anti-cavitation
and anti-noise.
Further sizing details are available in Performance!, Flowserve’s control valve sizing & selection software program (please contact your local Flowserve
representative for further details). The plug is typically pressure-balanced to allow smaller and more economical actuators. Flow over or under the plug
is available.
