Typical Applications
Chemical processing, marine and salt-water service, water and wastewater treatment, food and beverage utilities, compressed air, and corrosive-atmosphere installations where brass won't last — with built-in padlock capability for lockout/tagout points. Standard-port bore suits shutoff duty where some flow restriction is acceptable.
