Also known as wafer ball valves, these combine the slim body of a butterfly valve with the high flow rates of a flanged ball valve. Bolt these valves to ANSI flanges—they meet ASME standards for dimensions, material, and pressure-temperature rating. Use with water, oil, air, steam and inert gas such as helium.

For extra gripping power and a strong seal, the Yor-Lok fittings on these valves have two sleeves that bite into tubing as you tighten the nut. All are compatible with Swagelok®, Let-Lok, and Parker A-Lok fittings. These valves have a PTFE seal and a corrosion-resistant Monel ball and body that can stand up to aggressive and corrosive chemicals such as acetone.

No need to completely remove these valves from your line for servicing. The bolted three-piece body comes apart, so you can easily access their internal components. Fire-tested to meet American Petroleum Institute (API) 607, these valves securely isolate diesel fuel, fuel oil, kerosene, and gasoline to prevent the spread of fire.

Install these valves to start and stop the flow of diesel fuel, fuel oil, kerosene, and gasoline. Fire-tested to meet American Petroleum Institute (API) 607, these valves are designed to securely isolate fluid and prevent the spread of fire. Insert unthreaded pipe into the socket ends and weld to create a permanent, leak-tight connection.

Prevent boiler scale deposits and sediment buildup with these valves designed to meet ASME standards for boiler drainage applications.

Control the flow of steam, hazardous gases, and other vapors without risking leaks. These valves have an accordion-like bellows around the stem that expands as they open and contracts as they close, forming an airtight seal.
