Adjustable Reducing Valves - Code 44

Parker Conflow’s Code 44 is a reliable, adjustable reducing valve that provides a pre-determined outlet pressure irrespective of variation of inlet water pressure for dust suppression in underground mines.

Code 44 caters for a full range of outlet pressures including low, high and extra high and allows for simple screw adjustment of pressure reduction range up to 124 bar.

The valve operates on a simple throttling principle. The throttle adjustment is achieved by the downstream pressure acting on a spring-loaded piston to open and close the reducing valve. Thus the flow through the valve is reduced and increased as the inlet pressure fluctuates, in order to maintain constant downstream pressure. Adjustment of the set pressure is carried out by increasing or reducing the spring compression by turning the adjusting screw.

Available in 1/2", 3/4", 1" and 1 1/4"” sizes and to a maximum working pressure of 206 bar.

Markets:
• Quarrying
• Mining

Features/Benefits:
• Can cater for Low, High and Extra High outlet pressure types.
• Either pre-set or customer adjustable.
• Extremely robust, Brass manufacture.
• Reliability - maintains a constant downstream pressure.
• Adjustable in specified range, flexible to suit requirements.

Applications:
• To reduce the water pressure to a level suitable for dust suppression in underground mines.
• Pressure reduction for water circuits on cutting machines, i.e. motor cooling circuits, dust suppression circuits and machine mounted fire hoses.
