Watts 0590713 Valve
For high-efficiency hydronic management, the Watts 0590713 Valve (Series HAV) delivers precision air removal across residential and commercial heating circuits. This 1/4" HAV automatic vent valve is engineered to eliminate air pockets in baseboards, convectors, and radiators, preventing the common service calls associated with noisy pipes and poor heat distribution. Featuring a two-piece chromed brass body, the unit integrates a moisture-retaining cellulose fiber disc system. When dry, these discs permit trapped air to escape; once saturated by system water, they expand to ensure a positive shut-off, preventing leaks.
Designed for the field technician, the Watts HAV-1/4 includes a replaceable cartridge that allows for rapid maintenance without requiring a full system blowdown. This hydronic air vent is rated for a maximum pressure of 125 psi and temperatures up to 240°F, making it suitable for both hot water and low-pressure steam applications. For manual overrides, the heat-resistant ABS handwheel provides immediate control, while the stainless steel check valve adds a layer of protection against backflow. Whether you are troubleshooting a cold radiator or performing a new boiler installation, this automatic air purger ensures peak thermal exchange and system longevity.
Key Benefits- Maintenance Without Shutdown: The internal cartridge is fully replaceable without draining the system, minimizing labor time on-site.
- Dual-Mode Operation: Offers both automatic air venting through hygroscopic discs and manual venting via the integrated handwheel.
- Robust Construction: Built with a chromed brass body, copper thermostat assembly, and stainless steel check valve for industrial-grade durability.
- Versatile Compatibility: Seamlessly integrates into 1/4" NPT high points, suitable for water and 10 psi low-pressure steam systems.
How do I handle a leaking vent valve?
If the Watts 0590713 begins to weep, it typically indicates the cellulose discs have reached the end of their service life or are fouled by debris. Because of the built-in check valve, you can simply unscrew the handwheel and replace the cartridge without isolating the radiator.
Can this be mounted horizontally?
For optimal performance of the automatic vent mechanism and to ensure the air rise is correctly captured, these valves should be installed in a vertical orientation at the highest point of the piping or heating unit.
What is the maximum operating pressure?
The Watts HAV series is rated for a maximum working pressure of 125 psi (8.6 bar), which covers the vast majority of residential and commercial hydronic applications.
