allowing technicians to maintain optimal head pressure by modulating water flow through the condenser

Solid-State Accuracy: Eliminates mechanical drift with electronic sensing

while the mechanical position indicator provides clear visual confirmation of the blade status

allowing for both the low-volume flow required to prevent oxidation during copper brazing and the higher pressures needed for leak testing R-410A line sets

Technicians often rely on the 632477R for troubleshooting furnace short cycling or ignition failures where a faulty pressure signal is suspected

Sporlan 4274-00 Valve R-410A allowing technicians to maintain optimalThe Sporlan 4274 00, model R38E147M, is a heavy duty, 2 way normally closed solenoid valve designed for high performance refrigerant flow control in commercial refrigeration and large scale air conditioning systems. This pilot operated valve features 7 8" ODF sweat connections, allowing for efficient brazing without the need for disassembly, which protects internal components from heat damage during installation. Engineered for high pressure
