1/4" One Piece Ball Valve – Compact Standard Port Design

The 1/4" one-piece standard port ball valve is designed for small-diameter threaded piping systems requiring reliable shut-off performance in a compact form. This stainless steel one-piece ball valve features a single-piece body construction that minimizes potential leak paths while maintaining serviceability through the threaded end connections.

Manufactured from 316 stainless steel, this valve provides corrosion resistance and long-term durability in industrial and process environments. The standard (reduced) port bore offers controlled flow while allowing a more compact valve body than full-port designs. Compared to full port valves, the smaller internal bore allows for a more compact valve body while maintaining effective shut-off performance.

Rated to 1000 WOG, this threaded one-piece ball valve includes female NPT connections for straightforward installation into standard 1/4" piping systems. PTFE seats deliver reliable sealing performance, while the blow-out proof stem and quarter-turn lever handle with locking device ensure secure, controlled operation.

Because of its compact, single-piece design, this valve is commonly used in general industrial systems, compressed air lines, instrumentation lines, OEM equipment, and small-diameter piping systems where space efficiency and reliable shut-off are required.

For larger compact shut-off valves, see our 1 piece ball valves.

For smaller compact options, view mini ball valves.

For applications requiring higher flow capacity, consider full port ball valves.

Why Choose 1/4" One Piece Ball Valves

The 1/4" one-piece ball valve is ideal for compact systems where space is limited and reliable shut-off is required. Its reduced port design allows for a smaller valve body while maintaining dependable performance in threaded piping systems.

• Compact size for small diameter piping systems
• Durable one-piece construction with fewer leak paths
• Cost-effective solution for general shut-off applications
• Suitable for industrial, OEM, and process systems

When to Choose a 1/4" Ball Valve

• Small diameter piping systems (1/4")
• Applications where space is restricted
• Systems where full flow is not required
• General-purpose shut-off in air, water, or fluid lines
