1" One-Piece Ball Valve – Compact Standard Port Design

The 1-inch one-piece standard port ball valve is designed for threaded piping systems requiring reliable shut-off performance in a compact form. This 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 ball valve provides corrosion resistance and long-term durability in industrial and process environments. The standard (reduced) port bore provides 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" piping systems. PTFE seats deliver reliable sealing performance, while the blow-out proof stem and quarter-turn lever handle with locking device ensure secure and controlled operation.

Because of its compact, single-piece design, this valve is commonly used in industrial process systems, compressed air lines, OEM equipment, and applications requiring space efficiency, corrosion resistance, and dependable shut-off performance

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" One Piece Ball Valves

The 1" 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" Ball Valve

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