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 installed in either the horizontal or vertical orientation.

• Prevents rooms (zones) from overheating due to gravity circulation
• Elastomer seal provides positive, shut-off eliminating the need for an isolation valve
• Brass body and non-ferrous internals
• Straight angle configuration allows for quick and easy installation
• Vertical design option saves installation time and material
• Turn knob for system draining or valve bypass
• Compact, lightweight design
