Hand Expansion Valves


The Hand Expansion Valves SEV series features a calibrated, adjustable seat nut flow regulating valve. Expansion valves are ideal for metering of flashing expansion of liquid refrigerants. The slotted seat nut design is more tolerant to dirt particles than tapered plug expansion. Hand wheels are red to distinguish them from shut-off valves.
