B&G Hydrotrol Flow Control Valves

B&G Hydrotrol Flow Control Valves Prevent overheating due to gravity flow The Hydrotrol (HT) flow control valve is used to prevent overheating of zones due to gravity flow in hydronic heating systems and will permit summer/winter operation of indirect water heater. The HT valve allows fluid to pass when the system or zone pumps start. When the system or zone pumps are not operating, the HT valve remains closed, preventing gravity circulation. The HT valves are designed with a 1/2 turn knob that can be manually opened when draining the system or for bypass purposes. The HT valve can be... Read more

B&G Copper Red Ring Monoflo Fittings

B&G Monoflo Fittings A single pipe serves as both supply and return. Connect risers to the main, assuring proper diversion of water to each heating unit regardless of type and its position in the system. Recommended for most installations including cast iron non-ferrous baseboards, free-standing radiation or convectors. Only one fitting is needed for most installations for adequate diversion for upfeed radiation. For most applications, a second fitting can be used if higher resistance is required.... Read more
