250020-353 Inlet Valve Kit Diaphragm for Sullair Compressor

The intake valve can be said to be a combination of intake control valve, with intake control, loading and unloading control, capacity control, discharge and release, prevent unloading or stop oil injection and other functions, its operation law can be summarized as: power load, power loss unloading.Compressor intake valves generally have rotating disc and reciprocating disc two mechanisms.

There are two ways to control the intake valve: one is the switch mode, when the pressure of the gas storage tank reaches the high limit set value, close the intake;When the pressure reaches the low limit, re-open the air intake.The other is the capacity adjustment mode, when the gas tank reaches a certain pressure, the inlet is closed under the control of the proportional valve, and the inlet is further reduced when the pressure of the gas tank further increases.When the gas tank pressure is slightly reduced, the air inlet will be increased, so that the pressure is stable in a certain range;When the pressure does not reach the adjustable pressure, the intake valve disc is fully open, and the air inlet is fully open.

250020-353 Inlet Valve Kit Diaphragm can perfectly replace the original spare parts, in line with the original manufacturer standards.
