AntiDrain and Relief Valve (820 PSI) — Professional Grade Key benefits Prevents dry starts and reduces pressure surges by maintaining system pressure within the 8 to 20 PSI relief range. Protects engine health during extended operation, helping maintain performance and improve conversion rates. Built for professional use by commercial maintenance crews, service technicians, and equipment operators who need reliable, durable components. Why you need it Reduces wear and damage caused by lowpressure starts and sudden pressure spikes. Keeps systems stable during long duty cycles, reducing unscheduled downtime and component replacement. Designed to perform reliably under the demanding conditions encountered in commercial and industrial service environments. What makes it stand out Durable construction that resists vibration, temperature swings, and pressure changes common in heavy use applications. Purposebuilt for professional maintenance and field service applications rather than occasional consumer use. Precisely specified relief range of 8 to 20 PSI to control pressure behavior and prevent harmful drain conditions. Function and compatibility Function: antidrain and pressure relief to maintain system pressure and prevent dry starts and surges. Compatibility: intended for professional commercial and industrial equipment where antidrain and relief protection is required. Suitable for use by maintenance crews, service technicians, and equipment operators in fleet and heavy equipment contexts. Performance attributes Relief range: 8 to 20 PSI for controlled pressure management. Designed to withstand vibration and temperature variations without loss of function. Maintains reliable operation under changing pressure conditions to support prolonged equipment use. Typical applications Fleet maintenance: Installed on service vehicles and fleet equipment to prevent dry starts after long idle periods and to reduce pressurerelated failures. Field service and : Used by technicians onsite to stabilize pressure during diagnostics and repairs in commercial equipment. Heavy equipment operation: Protects engines and systems in construction, agriculture, and industrial machines that run for extended shifts or under variable environmental conditions. Summary A professionalgrade antidrain and relief valve specified for 8 to 20 PSI relief. Durable and designed to resist vibration, temperature swings, and pressure changes, it helps prevent dry starts and pressure surges while supporting engine health during extended use. Ideal for commercial maintenance crews, service technicians, and equipment operators who require consistent, reliable pressure control.
