HONGSEN EVR Refrigeration Solenoid Valve Bodies Without Coil
Product Description
Product Overview
HONGSEN EVR Series solenoid valves are one-way shut-off valves designed for liquid, suction and hot-gas lines in commercial refrigeration, cold-storage and air-conditioning systems.
EVR3 models use direct operation and can open without a pressure differential. Larger EVR models use pressure-assisted or servo operation and require a minimum pressure difference between the inlet and outlet.
The series is available with SAE flare or ODF solder connections. Valve bodies and coils are supplied separately, allowing the operating voltage to be selected according to the local power supply.
Important: All variants on this product page are valve bodies only. The solenoid coil must be ordered separately.
