Conbraco 36C-104-01 Valve

The Conbraco 36C-104-01 is a high-capacity water pressure reducing valve engineered for precision fluid control in residential and commercial plumbing systems. This 3/4 inch Union NPT x 3/4 inch Female NPT regulator is built with a rugged bronze body, designed to handle a 400 PSI max inlet pressure while maintaining a stable downstream flow. The factory-set delivery pressure is 50 PSI, though the unit offers a field-adjustable 25-75 PSI outlet adjustment range to meet specific site requirements. For technicians dealing with high-velocity debris, the integral stainless steel strainer is a critical feature that prevents seat damage and ensures the longevity of the EPDM diaphragm and stainless steel hardware.

Installation professionals will appreciate the balanced piston design, which prevents supply pressure fluctuations from affecting the set delivery pressure. This lead-free bronze pressure regulator is ASSE 1003 and CSA B356 certified, making it suitable for potable water applications where dynamic pressure control is essential to protect fixtures and appliances from thermal expansion and water hammer. The replaceable cartridge design allows for streamlined servicing without removing the entire valve body from the piping run.

Key Technical Benefits

• Durable Construction: Heavy-duty bronze body with stainless steel internal components for corrosion resistance in hard water environments.
• Integrated Filtration: The built-in stainless steel strainer protects the valve seat from scale and silt, reducing maintenance callbacks.
• Broad Pressure Range: Accommodates high-pressure water reduction needs with an adjustable range suitable for multi-story residential units.
• Ease of Service: Features a union connection that simplifies installation and provides a reliable seal under high-flow conditions.
• Certified Compliance: Meets NSF/ANSI 372 lead-free requirements for potable water safety.

Frequently Asked Questions

How do I adjust the outlet pressure on the Conbraco 36C series?
To adjust the water pressure regulator, loosen the locknut on the adjustment bolt and turn the bolt clockwise to increase downstream pressure or counter-clockwise to decrease it. Always verify settings with a pressure gauge installed downstream.

What causes a pressure reducing valve to hum or vibrate?
Vibration or "chatter" is often caused by high-velocity flow through a restricted orifice or air trapped in the line. Ensure the 3/4 inch NPT fittings are secure and the valve is sized correctly for the peak demand of the system.

Can this valve be installed in any orientation?
While the Conbraco 36C-104-01 can be installed horizontally or vertically, it is best practice to install it horizontally with the stainless steel strainer accessible for periodic cleaning to maintain optimal GPM flow rates.
