SPECIFICATIONS
Mark 701/702 SeriesHigh-Flow and Super High-FlowControl Valves
The Mark 701/702 high-flow and super high-flow sliding gatecontrol valves provide:
� Shorter stroke than a globe or plug-style valve• Faster response• Longer packing and seat life• Stem packing is four times deeper than stem
travel — for greater protection against leakage• Smaller and lighter weight than globe-style valves
� Straight through -flow• Less turbulence, erosion and noise• Improved rangeability
� Ease of maintenance• Interchangeable seats and Cv’s• Fewer spare parts• Self-cleaning seats• No gaskets or o-rings
Sizes: 1/2” through 2” (DN15 through DN50)
End Connections• Threaded (NPT, BSPT, BSPP)• ANSI Flanges (150#, 300#)• DIN Flanges (PN10/16, PN25/40)
Body Materials• Ductile Iron• Bronze• Carbon Steel (WCB)• Stainless Steel (CF8M)
Trim Materials:• 303SS for CI, DI, BRZ & CS body valves• 316SS for SS body valves
Seat Materials:• Jorcote on SST — Standard• Jorcote/Jordanic on SST — For Severe Service• Chrome Plated SST — Economical option for light duty
