Caleffi Discal Series 551 Air Separators Brass NPT
Air separator with automatic ½" check valve (code 561402A) to mount expansion tank on bottom thread. Brass body. Glass reinforced nylon internal element. Max. working pressure: 150 psi. Working temperature range: 32—250°F.In heating and air conditioning control systems, the circulation of water containing impurities may result in rapid wear and damage to components such as pumps and control valves. It also causes blockages in heat exchangers, heating elements and pipes, resulting in lower thermal efficiency within the system. The dirt separator separates off these impurities, which are mainly made up of particles of sand and rust, collecting them in a large collection chamber, from which they can be removed even while the system is in operation. This device is capable of efficiently removing the smallest particles, with low head loss.$82.89 -
1" Caleffi 663 Series Distribution Manifold
1" NPT Inlet Ball valves and 3/4" outlets. This pre-assembled distribution assembly with Return distribution manifold including Built-In Shut-Off Valves suitable for Thermo-Electric Actuators, and Supply distirbution manifold including Manually-Adjustable Balancing Valves. MAX working pressure: 150 psi. MAX temperature 210 F.Distribution manifolds for radiant panel systems are used to optimally distribute the heating fluid in floor heating system circuits and ultimately improve the control of heat emission from the panels. The manifolds ensure that the flow of each circuit is regulated precisely and also control the shut-off, venting and automatic removal of air from the system.$229.65 -
