Conbraco 36C-105-01 Valve

The Conbraco 36C-105-01 is a high-performance 1-inch NPT pressure reducing valve engineered for precision water pressure regulation in commercial and residential distribution systems. This heavy-duty water pressure regulator features a rugged bronze body and an integral stainless steel strainer to protect downstream equipment from debris and sediment. Designed to handle a maximum inlet pressure of 400 PSI, this compact direct-acting valve utilizes a balanced piston design to maintain stable discharge pressure regardless of supply fluctuations.

For field technicians, the 36C-105-01 offers superior serviceability with its sealed spring cage, making it suitable for vault installations where moisture is a factor. The outlet pressure is factory set at 50 PSI but remains fully adjustable within a 25–75 PSI range via the stainless steel adjusting screw. The 1" Union NPT x 1" Female NPT connection allows for simplified inline maintenance, while the built-in thermal expansion bypass provides critical protection against pressure spikes caused by water heating. This Apollo PR series valve meets ASSE 1003 and CSA B356 standards for reliable performance in demanding piping layouts.

• Broad Pressure Control: Adjusts from 25 to 75 PSI with a 400 PSI maximum inlet rating to stabilize fluctuating municipal lines.
• Contractor-Grade Durability: Constructed with a corrosion-resistant bronze body, EPDM seat, and FDA-grade nitrile O-rings for long-term reliability.
• Simplified Maintenance: Features a bottom cleanout plug for direct access to the seat disc and stainless steel strainer without removing the valve from the line.
• Thermal Protection: Integrated bypass prevents damage from thermal expansion in closed-loop systems.
• Vault-Ready Design: The sealed spring cage protects internal components from external environmental hazards.

How do I adjust the outlet pressure on the 36C-105-01?
Loosen the locknut on the top of the valve and rotate the stainless steel adjusting screw clockwise to increase pressure or counter-clockwise to decrease it. Verify final settings with a downstream gauge during flow conditions.

Can this valve be serviced without cutting the pipe?
Yes, the 36C series is designed for inline servicing. The union connection and the bottom access plug allow a technician to inspect the seat disc and clean the strainer while the valve body remains installed.

Is this model suitable for potable water systems?
While the 36C-105-01 features FDA-grade soft goods, always verify your local lead-free plumbing codes (such as NSF/ANSI 372) before installation in potable water lines, as some jurisdictions require the lead-free "LF" variant.
