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.
