Conbraco 20-205-03 Valves

The Conbraco 20-205-03 Valves is a professional-grade liquid level gauge set designed for high-performance fluid monitoring in commercial boilers and industrial vessels. As a heavy pattern water gauge, this assembly is engineered with a robust rough bronze body, offering significantly higher service ratings than standard light-duty patterns. Featuring 1/2 inch MNPT male connections, the set is built for a precision fit with 5/8" OD gauge glass. The integration of Teflon stem packing and an EPDM glass seal ensures superior leak resistance and chemical compatibility across a wide range of media. Operating at a maximum working pressure of 400 PSI at 100°F and maintaining integrity at 200 PSI @ 400F, these valves are a staple for technicians requiring reliable boiler sight glass valves. The composite plastic type wheel provides a durable, heat-resistant grip for manual operation, ensuring the Apollo 20-205-03 remains a go-to choice for HVACR contractors prioritizing system safety and longevity.

• Heavy Pattern Bronze Construction: provides a reinforced valve body for demanding high-temperature and high-pressure steam applications.
• High-Grade Seals: utilizes Teflon stem packing and EPDM gaskets to prevent bypass leakage and extend service intervals.
• Versatile Compatibility: engineered for standard 1/2" NPT pipe threads and compatible with 5/8" regular or high-pressure gauge glass.
• Thermal Resilience: rated for extreme environments up to 400°F, making it suitable for standard ASME boiler code requirements.
• Field-Proven Reliability: designed by Apollo Valves to meet rigorous industrial standards, including CRN registration (OF6616.5C).

• Does this set include the sight glass and protector rods? No, the 20-205-03 is a valve set only; the gauge glass and protection rods must be sized and purchased separately based on your vessel's center-to-center dimensions.
• What is the difference between a standard and heavy pattern valve? Heavy pattern valves like the 20-200 series feature thicker wall sections and higher-grade internal components, allowing for higher pressure/temperature ratings compared to the 20-100 series.
• Are these valves equipped with automatic ball checks? This specific model is a non-automatic version; for applications requiring automatic shut-off in the event of glass breakage, refer to the 20-250 series models.
