Crankcase Pressure Regulators, type KVL<br />
Introduction<br />
KVL crankcase pressure regulators are used to<br />
protect the compressor motor against overload<br />
experienced during startup after long off periods<br />
or just after defrost periods.<br />
They are installed in the suction line of<br />
refrigeration systems.<br />
