Parker 73218BN5VN00 Valve

The Parker 73218BN5VN00 is an industrial-grade, 2-way normally closed solenoid valve designed for high-cycle performance in water, light oil, and neutral gas applications. Featuring a 3/4" NPT connection and a pilot-operated diaphragm, this valve requires a minimum differential pressure of 5 PSI to function correctly, supporting a maximum operating pressure of 150 PSI. The NBR (Buna-N) seal provides excellent resistance against standard fluids, ensuring reliable shut-off in commercial HVAC and plumbing systems. This model is also identified as 73218BN5VN00N0 and is commonly integrated into systems requiring automated fluid control. Engineered for durability, the brass body construction handles thermal stress efficiently while maintaining flow integrity. Contractors favor this series for its predictable flow coefficient (Cv) and straightforward field maintenance. When replacing existing units, ensure the voltage of your current coil matches the installation requirements, as this valve body is designed for seamless pilot-operated valve transitions in pressurized lines.

• High Flow Capacity: Optimized internal geometry ensures minimal pressure drop across the 3/4 inch orifice.
• Reliable Sealing: The NBR seat material provides a bubble-tight seal for consistent performance in low-to-medium temperature applications.
• Standardized Fit: Fully compatible with 73218BN5VN00N0 specifications, simplifying inventory and field replacements.
• Robust Construction: Heavy-duty brass body resists corrosion and mechanical fatigue in demanding environments.
• Pilot-Operated Efficiency: Utilizes system pressure to assist valve actuation, reducing the power consumption required for the coil.

Does this valve require a minimum pressure to open?
Yes, as a pilot-operated diaphragm valve, it requires a minimum pressure differential of 5 PSI to lift the diaphragm and allow flow.

Can the NBR seal be used with aggressive chemicals?
NBR is ideal for water, air, and light oils; however, for high-temperature steam or corrosive chemicals, verify fluid compatibility with Buna-N before installation.

Is the coil included with this valve body?
This part number typically refers to the valve body and internal kit; always verify your specific coil voltage and housing requirements for a complete assembly.
