The Sporlan Y1236-C pressure differential valve is designed for use on high pressure oil return systems or others applications where a differential pressure regulator is required. The valve permits the oil level control mounted at the compressor to feed at any specified level because the pressurized oil at the control is slightly greater than
crankcase pressure. Without the Y1236-C, excessive pressure drop across the mechanical oil level control would cause the control to overfeed the compressor. This occurs because more force is required on the float ball, thereby a higher oil level, to overcome the pressure drop through the port to close the oil level control.
The Y1236-C reduces the inlet pressure by controlling a differential across the valve outlet and the force supplied to the valve's element. With high pressure oil return systems, suction pressure is supplied to the element when located between the oil separator/reservoir and the oil level control.
The Y1236-C includes a removable 100 mesh inlet strainer to protect the valve from circulating contaminants.

• The valve is adjustable from a 10 to 25 psi differential.
• Factory setting 17 psi.
