The Mark 200 is one of the most dynamic Flowserve control valve offerings designed to meet the needs of high-pressure large capacity applications. It offers the highest flow capacity, as well as fast, easy maintenance in both gas and liquid control. The Mark 200 also has longer stroke lengths, providing finer control and resulting in superior process control in smaller valve sizes.

Features & Benefits
- Higher Cv capacity allows for smaller, more cost effective valve sizes
- Double Top Stem Guiding moves the critical function of assuring alignment of the trim out of the flow path
- Cage Guiding provides an additional alignment point, ideal for large body valves
- Single Piece Plug & Stem assures integrity of the assembly, avoiding side load fracturing
- Cage Contour provides flow characteristics for standard and severe service trims
- Floating Seat is clamped in-place after alignment to ensure tight-shutoff and easy service
- Bolted Bonnet eliminates service issues related to threaded designs
- Severe Service Trim options can easily be designed or retro-fitted into standard trim valve
