Conbraco 10-512-B35 Valve

The Conbraco 10-512-B35 is a high-performance ASME Section VIII certified steam pressure relief valve designed specifically for overpressure protection in HVACR and industrial applications. Built with a rugged plain brass finish and a durable stainless steel spring, this 1/2" safety valve is factory-set at 35 PSI, providing a certified discharge capacity of 258 pounds per hour. As a veteran technician, you know that National Board capacity certification is non-negotiable for system safety; the 10-512 series delivers this reliability within a compact profile ideal for cookers, sterilizers, and small steam boilers. This model features a 1/2" Male NPT inlet and a 1/2" Female NPT outlet, ensuring a straightforward, secure fit into standard piping. The silicone seat provides superior tightness to prevent simmering, while the design supports a maximum working temperature of 300°F. When maintaining narrow tolerances between operating and set pressures, this Apollo Valves component offers the precision required to prevent chattering and premature seat wear in demanding thermal environments.

• ASME Section VIII Certified: Ensures compliance with strict safety codes for steam pressure vessels and systems.
• Optimized Capacity: Rated at 258 lbs/hr to provide rapid pressure normalization during overpressure events.
• High-Temp Reliability: Engineered for steam environments up to 300°F using an ASTM B16 brass body.
• Positive Seat Tightness: Utilizes high-grade silicone seating to reduce leakage and maintain system pressure efficiency.
• Compact Maintenance: The 10-512-B35 design allows for easy installation in tight quarters without sacrificing flow performance.

Is the Conbraco 10-512-B35 suitable for air or gas service?
While often used for steam, this specific configuration is ASME Section VIII certified for steam service. For air or gas applications, always verify local code requirements and ensure the capacity meets the specific fluid dynamics of your equipment.

What causes a safety relief valve to leak or "chatter" at 35 PSI?
Chattering often occurs when the operating pressure is too close to the set pressure (ideally, keep a 10-20% margin) or if the outlet piping is inadequately supported, putting mechanical stress on the valve body.

Where is this valve typically used in a facility?
This 1/2" MNPT x FNPT valve is a standard choice for sterilizers, steam kettles, and commercial cookers where precise 35 PSI pressure relief is critical to protect both the operator and the vessel.
