Valve Configuration
Female NPT Ends
Female NPT threaded connections on both sides provide straightforward installation into compatible threaded piping systems.
Full-Port Ball
The full-port internal passage helps maintain strong system flow while reducing restriction through the valve when fully open.
Lever Handle
The manual lever provides fast quarter-turn opening and closing with clear visual indication of valve position.
Construction Details
The valve body is manufactured from forged brass for dependable strength, durability, and corrosion resistance in compatible piping applications.
A full-port internal passage helps maximize flow capacity and minimize pressure drop across the valve when fully open.
The quarter-turn lever handle provides simple manual operation, while female NPT threaded ends allow convenient installation into new or existing threaded piping systems.

Full Port vs. Standard Port
Full Port
A full-port valve uses a larger internal opening designed to more closely match the connected pipe size and reduce flow restriction.
Standard Port
A standard-port valve uses a smaller internal passage and may create more pressure drop through the valve.

Our valve, fitting, and industrial product specialists can help review your valve size, FIP connection requirements, pressure rating, handle configuration, media compatibility, and application before you order.
