3/4" Pressure Reducing Valve

Professional Pressure Control – Zurn 34-600XL 3/4" Pressure Reducing Valve for Consistent System Performance

The Zurn 34-600XL 3/4" Pressure Reducing Valve is built to deliver stable outlet pressure in systems with fluctuating or high inlet pressure, helping to protect plumbing infrastructure and extend equipment life. Engineered with a corrosion-resistant cast bronze body and featuring a balanced piston design, this valve delivers responsive performance in both commercial and residential water service lines.

Ideal for potable water applications, the 34-600XL maintains downstream pressure within an adjustable range while preventing pressure buildup with its integrated bypass function. Whether specified for new construction or replacement work, it offers the reliability professionals expect on the job site.

Product Highlights

• Balanced Piston Design – Delivers fast reaction to pressure fluctuations for steady outlet pressure control.
• Integral Bypass Check – Allows excess pressure to bleed off, protecting downstream components from over-pressurization.
• Serviceable Strainer – Accessible cap for cleaning the integrated strainer without removing the valve from the line.
• Durable Build – Constructed with cast bronze and corrosion-resistant internal components for long-term service.
• Lead-Free Certified – Compliant with NSF/ANSI 61 and 372 standards for use in potable water systems.

Specifications

Installation Considerations

This valve is intended for horizontal installation with the spring bonnet in the upright position. While installation is straightforward for experienced plumbers, it requires thread-sealing compound, pressure testing after installation, and access to system isolation valves. Proper installation ensures pressure control accuracy and prevents debris from entering the valve mechanism.
