Conbraco Industries 37LF-202-01 Valve
The Conbraco Industries 37LF-202-01 is a high-performance 3/4" vacuum relief valve engineered for critical negative pressure protection in commercial and residential hydronic systems. This lead-free model features a durable DZR C27541 brass body and a reinforced brass poppet, providing superior structural integrity compared to standard residential units. Designed to handle flow rates up to 16 CFM, it effectively prevents tank collapse and water siphoning by automatically admitting air when system vacuum levels reach less than 1/2" Hg. This part is the 37LF-202-01 direct replacement for 37-202-01, satisfying modern potable water requirements while maintaining its 200 PSI pressure rating and 250°F maximum temperature threshold. With a stainless steel spring and EPDM seat washer, this valve ensures reliable sealing and resistance to scaling in harsh water conditions. It is also suitable for low-pressure steam applications up to 15 psig, making it a versatile go-to for veteran contractors.
Key Benefits:- Lead-free construction: Complies with NSF/ANSI 372 and federal public laws for potable water safety.
- High Relief Capacity: Rated for 16 CFM at 2" Hg to protect large-capacity storage tanks.
- Broad Compatibility: Standard 3/4" NPT connection serves as a universal hot water heater vacuum relief solution.
- Industrial Grade Materials: Features a rough chrome or satin brass finish with a stainless steel spring for longevity.
- Automatic Response: Protects against siphoning and "implosion" by opening at vacuum levels under 0.5" Hg.
- Where should I install the 37LF-202-01 on a water heater? To ensure proper function and code compliance, install the valve in the cold water supply line at least 6 inches above the top of the tank.
- Can this valve be used for steam systems? Yes, it is rated for LP steam applications with a maximum pressure of 15 psig.
- What is the difference between the 37LF-202-01 and the 37-202-01? The 37LF-202-01 is the modern lead-free version designed to replace the now-obsolete 37-202-01 while maintaining identical physical dimensions and performance specs.
