Anvil Gruvlok Series 7800 Check Valve for use in Grooved-End Piping Systems - Nitrile

Anvil Gruvlok Series 7800 Check Valve for use in Grooved-End Piping Systems - Nitrile

This compact and cost-effective valve ensures low pressure-drop and non-slam performance, offering a superior alternative to traditional flanged and wafer valve assemblies. With a swing clapper design, quick closure, and FM-approved anti-water hammer features, the Series 7800 delivers optimal flow control and prevents clapper flutter.

Note: Not for use in copper systems
