Overview

The FNW 150PSI 3" True Union Ball Valve FNW340 FE delivers reliable on-off flow control for industrial applications. Built with PVC construction and rated for 150 PSI at 73°F, this full-port design minimizes flow restriction while the true-union socket connections allow quick disconnection without disturbing adjoining piping. Manual handle operation provides simple, dependable actuation for hydraulics, pneumatics, water systems, and general industrial fluid transfer.

Key Features

• Full-port design for minimal pressure drop and maximum flow capacity
• True-union socket connections enable quick disconnect and service without system shutdown
• PVC body with PVC ball and EPDM O-rings for reliable chemical compatibility
• O-ring energized seats for tight shutoff
• Manual lever handle for simple on-off operation
• Compact, durable construction suitable for industrial and commercial systems
