  1. Caleffi Discal Series 551 Air Separators Brass NPT

    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.

  3. Caleffi Series 553 Automatic Filling Units 1/2"Union NPT Male Inlet with 1/2" NPT Female Outlet

    Caleffi Series 553 Automatic Filling Units 1/2"Union NPT Male Inlet with 1/2" NPT Female Outlet

    Caleffi Series 553 Automatic Filling Units
    The AutoFill™ automatic filling valve is a pressure reducing valve with a compensating seat, an inlet filter, a shut-off valve and a check valve. It is installed on the water inlet piping in sealed heating systems, and its main function is to maintain the pressure of the system to a preset value, automatically filling up with water as required. This valve has been designed as pre-adjustable, which means it can be adjusted at the required pressure value before charging the system. After installation, during the filling or topping-off phase, the water feed will stop automatically when the set pressure is reached. There are no levers to flip or valve to close. Preassembled with the backflow preventer, it features an atmospheric vent which is designed to protect drinking water systems from return flow, caused by back-siphoning or backpressure, of contaminated fluids. The 573 series has been specifically certified to standards CSA B64.3 and ASSE 1012.

  4. Caleffi Discal Series 551 Compact Air Separator 3/4" Sweat

    Caleffi Discal Series 551 Compact Air Separator 3/4" Sweat

    Air separator. Brass body. Stainless steel mesh internal element. ½" NPT bottom thread. Max. working pressure: 150 psi. Working temperature range: 32—250°F.
    Air separators are used to continuously remove the air contained in the hydronic circuits of heating and cooling systems. The air discharge capacity of these devices is very high. They are capable of removing automatically all the air present in the system down to micro-bubble level. The circulation of fully de-aerated water enables the equipment to operate under optimum conditions, free from any noise, corrosion, localized overheating or mechanical damage. Micro-bubbles, fuse together, increase in volume until they become large enough to rise to the top where they are automatically released.
