Pressure Compensated Constant Flow Control Valves

Pressure Compensated Constant Flow Control Valves are used in low pressure lubricating systems. The flow rate stays constant through changes in pressure. These valves do not require frequent adjustment and are especially suitable for use in automated plants, for elevated, distant, or hard to get at places. The various models have fixed flow rates that vary from 3 ounces per minute to 1 gallon per minute. The flow rate remains constant within plus or minus 20% for 3 to 9 ounces per minute, and within plus or minus 10% for 1 pint to 1 gallon per minute. This accuracy can be maintained with varying pressures, ranging from 15 PSI minimum to 125 PSI maximum, and with any oil having a viscosity of 400 SSU minimum to 750 SSU maximum.
