Instructions on Bypass Valve Selection
N-Form:
N=Built-in Pressure Bypass Valve
N type: built-in bypass valve, when the internal pressure of the heat sink is too large; the built-in pressure valve opens; the pressure can be released from the channel in the heat sink.
When a pressure bypass valve is required, there is no need to connect an external oil return line; it is convenient and practical
W-Form:
W=External Pressure Bypass Valve
W type: external pressure bypass valve, compared with N type, the advantage is that the heat sink with the same specification has no internal leakage channel, and the number of heat conduction fins is correspondingly increased; thereby increasing the heat dissipation area of the fins.
At the same time, the pressure relief effect of the external pressure bypass valve is better than that of the internal leakage form.
Note: When using an external bypass valve, it is necessary to connect an additional pipeline to the oil tank.
M-Form:
M=No Bypass Valve
M type: no bypass valve, the heat sink of the same specification has no internal leakage channel, and the number of heat conduction fins is correspondingly increased; thereby increasing the heat dissipation area of the fins.
There is no external valve and there is no need to connect an extra pipeline to connect back to the oil tank. But it is necessary to make sure that the medium entering the cooler is low pressure and no pulse pressure! Especially suitable for independent cycle use.
