Zurn Wilkins 500XL Water Pressure Reducing Valve with By-Pass (PRV).
Product Overview
The Zurn Wilkins 500XL Pressure Reducing Valve is designed to regulate and maintain safe water pressure in potable water systems. Built with a balanced piston design, it reacts smoothly to flow demand while protecting against fluctuations in inlet pressure. Its integral by-pass check valve relieves excess pressure caused by thermal expansion, safeguarding plumbing fixtures, appliances, and piping from damage.
Engineered for commercial plumbing systems and industrial water lines, the 500XL provides consistent performance and a high flow capacity. With a durable bronze body and corrosion-resistant internals, it is built for long-term reliability while meeting lead-free requirements.
