Midland Industries 46905SS Miniature Ball Valve 1/2 in Ss

Product Description

The MIDLAND INDUSTRIES 46905SS is a 1/2-inch miniature ball valve built for high-pressure fluid and gas service in tight spaces. It features a 316 stainless steel body, ball, and stem, paired with a PTFE seat and PTFE seals for broad chemical compatibility. The valve is rated to 1000 psi WOG (water, oil, gas) and 150 psi WSP steam pressure, with an operating temperature range of -36 to 368 degrees F. A butterfly handle operator provides quick quarter-turn shutoff. Plumbers, pipefitters, and mechanical contractors install this valve where space constraints or corrosive media rule out standard-size valves.

This miniature ball valve is suited for residential and light commercial plumbing, process piping, and HVAC hydronic systems where a compact, corrosion-resistant shutoff is required. The male-pipe-thread by female-pipe-thread (MPT x FPT) connection with a 1/2-14 thread size allows straightforward inline installation. The standard port design maintains reliable flow control in space-limited manifold runs, equipment connections, and service isolation points.

Compatibility

Designed as an OEM-style replacement or new-installation miniature ball valve for 1/2-inch MPT x FPT stainless steel piping systems requiring 1000 psi WOG pressure ratings.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC and IFGC codes. Shut off and depressurize the system completely before removing any existing valve or making new connections. Apply thread sealant or PTFE tape to male threads and avoid over-torquing, which can damage the stainless steel threads or PTFE seals. Confirm the butterfly handle has full clearance to rotate 90 degrees before finalizing the installation.
