Mark 33 Series – Boiler Feedwater Control Valve
The Mark 33 is a motor-operated valve featuring the Jordan sliding gate seat and heavy-duty industrial motors for proportional (resistance), on-off, 4-20 mA electronic control. Models include the Mark 33 in sizes 1/4" through 2" (DN8 through DN50), the high flow Mark 331/332 with Cv's up to 70 (60,34 Kv), and the Mark 39 with three-way body.
The Mark 33 delivers exceptional pressure drop abilities due to the short stroke of the sliding gate seat which permits greater utilization of the motor torque output.
The Mark 331/332 electric motor operated control valves feature high capabilities in relation to line size. With Cv's up to 70 (60,34 Kv) in a 2" (DN50) valve, the Mark 331/332 combines the superior accuracy of the sliding gate seat design with the heavy-duty Honeywell electric motor for reliable, long-term operation.
