Sporlan 4274-00 Valve R-410A allowing for both the low-volumeThe 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
