The Mark 601 and Mark 602 are used in applications that require higher
Cv (Kv) rating without using a larger valve. The high flow Mark 602 has
Cv's (Kv's) as high as 50 (43) and the super high flow Mark 602 has Cv's
(Kv's) up to 70 (60). The sliding gate seats help reduce the droop
commonly associated with high flow regulators.
Pressure Reducing Valve MK601/602
Size
- 1-1/2″ – 2″ (DN40 – DN50)
Cv (Kv)
- up to 70 (up to 60)
Diaphragm
- Jorlon, Stainless Steel, Buna-N, Viton
Setpoint Range
- 20 to 160 psi (1,4 to 11,0 bar)
Body Materials
- Ductile Iron, Bronze, Carbon Steel, Stainless Steel
Endconnections
- Threaded, ANSI Flanges (150#, 300#), DIN Flanges (PN 10/16, PN25/40)
Features and Benefits
- Shorter stroke than a globe or plug-style valve: faster response, less offset, smaller and lighter weight than globe-style valves, longer diaphragm life
- Straight-through flow: less turbulence, erosion and noise, improved rangeability, longer seat life
- Ease of maintenance: interchangeable seats and Cv’s (Kv’s), fewer spare parts, self-cleaning seats, no gaskets or o-rings
