Description
The Liebert W-0092S 3/8″ Sweat Check Valve permits flow direction control through an internal spring disc that opens under forward pressure and closes under reverse pressure to block back movement. It operates using pressure-responsive motion that regulates passage inside the unit without electrical input in HVAC systems. It is mounted in piping lines to maintain one-way movement of refrigerant or condensate. Its compact form supports tight installation, while the sweat connection provides secure joining with copper tubing, ensuring stable flow control and preventing reverse circulation inside connected sections of the system.
