Features
Choice of vent to atmosphere or pipe away models
Modular design provides flexibility of field installation and allows easy reconfiguration, repair or on-site upgrading
Oversized pressure and vacuum ports provide maximum flow capacity
Easily removable hood and cover for inspection and maintenance
Seat rings are both interchangeable and field replaceable
Protective screens at pressure and vacuum ports prevent entrance of foreign matter
Outlet adapter on the 2020B Series is one pipe size larger than the valve inlet flange to optimize flow capacity
Zero product loss when combined with a vapor recovery system
Replaceable and interchangeable pressure and vacuum seat rings
‘All-weather’ non-frosting and ice-resistant coating option available for valve seats and guides
Extended service options available for high temperature and chemical applications
