TeeJet Pressure Relief Valve 6815-3/4-300

The TeeJet 6815-3/4-300 Pressure Relief Valve is a professional-grade component engineered to provide precise and reliable pressure regulation in a variety of liquid-handling systems, most commonly found in agricultural and landscaping sprayers. This piston-type relief valve is designed to bypass excess liquid back to the supply tank or pump inlet, ensuring that line pressure remains constant and within the desired operating range. Constructed with a solid brass body, the valve is built for durability and long-term chemical resistance. It features hardened stainless steel seats, which provide superior wear resistance and a longer service life compared to standard brass seats. The extra-large valve passage ensures full flow with minimal pressure loss, contributing to the overall efficiency of the system. With a maximum pressure rating of 300 PSI, the TeeJet 6815-3/4-300 is suitable for a wide range of applications, especially those utilizing diaphragm, roller, and piston pumps. The valve is adjustable, allowing the user to easily set and maintain the desired pressure. Its design includes a secure locknut to prevent the pressure setting from changing due to vibration. The valve features a 3/4" male NPT inlet and a 3/4" female NPT outlet, making it compatible with many standard plumbing configurations. This essential component not only helps to maintain optimal spray performance but also protects the pump from damage caused by excessive pressure, making it a critical part of a well-functioning spray system.
