The Caleffi AngleMix 520 series thermostatic mixing valve is used in systems producing domestic hot water and easily mounts to the top of water heaters. The mixed temperature outlet is inline with the hot water inlet, facilitating trouble-free connection and reducing space required for installation. The AngleMix maintains the desired output temperature of the mixed water supplied at a constant set value compensating for both temperature and pressure fluctuations of the incoming hot and cold water. The mixing valve closes both inlet ports tight, eliminating temperature creep in recirculation loops. Also available as body only, for a wide variety of separately-ordered end connections, the angle style body design offers improved fluid dynamics for better performance and reduces installation labor and materials, eliminating a piping elbow in typical installations. The valve complies with NSF/ANSI/CAN 372, low lead, as certified by ICC-ES. Complies with ASSE 1017, CSA B125.3, UPC, IPC, Low Lead Laws and listed by ICC-ES for use in accordance with the U.S. and Canadian plumbing codes.

PRODUCT FEATURES:

Double the protection: Captures two forms of debris that can damage or shorten the life of heat exchangers, circulators, valves and polymers: ferrous debris such as magnetite, and non-ferrous debris such as copper shavings, solder, lime-scale fragments, silica and pipe compound.

Unique dual magnetic fields: Two powerful neodymium rare-earth magnetic fields attract and capture ferrous oxide impurities and allow simple blowdown - no disassembly required

Unique dual magnetic fields: Two powerful neodymium rare-earth magnetic fields attract and capture ferrous oxide impurities and allow simple blowdown - no disassembly required

Fast and easy clean hands purging: Pull out the magnetic pull rod from drywell on top, unclip the External barrel magnetic collar and open the purge valve to simply release the captured magnetic impurities and purge all dirt.

Caleffi 551004A Automatic Air Vent High Performance 1/2" NPT
DISCALAIR automatic air vents release air that forms in the hydraulic circuits of heating and air conditioning systems, with pressures to 150 psi. The venting air discharge capacity is very high, capable of discharging over 4 standard cubic feet per minute (SCFM). The circulation of fully de-aerated water or glycol-water fluids enables the equipment to operate under optimum conditions, free from noise, corrosion, localized overheating or mechanical damage.

Caleffi 551028A Air Separator 1" Sweat DISCAL
The DISCAL air separator is 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, fusing with each other, increase in volume (get larger) until they become large enough to rise to the top where they are automatically released.

Caleffi 553549A AutoFill Filling Valve 1/2" Sweat x NPT
The automatic filling valve is a device consisting of a pressure reducing valve with compensating seat, visual system pressure setting indicator, an inlet filter, anti-scale internal parts, 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 stable at a set value, automatically filling up with water as required. This valve has been designed as pre-adjustable, which means that it can be adjusted at the required pressure value before the system charging phase. After installation, during the filling or topping-off phase, the water feed will stop when the set pressure is reached filling 50% faster than other valves. There are no levers to flip or valve to close. Pre-assembled with the 573 series backflow preventer, the AutoFill Combo features an atmospheric vent which is designed to protect drinking water systems from return flow, caused by back-siphoning or back pressure, of contaminated fluids. The 573 series has been specifically certified to standards CSA B64.3 and ASSE 1012.
