Midland Industries 949170 3 Inch Ball Valve Fpt 316 Ss

Product Description

The MIDLAND INDUSTRIES 949170 is a two-piece, full port ball valve designed for demanding industrial and commercial fluid control applications. Built with a 316 stainless steel body and ball, it carries a 1000 psi WOG (Water, Oil, Gas) pressure rating and handles temperatures from -60 to 450 degrees F. The 3-inch FPT (female pipe thread) connections allow for direct inline installation. A locking handle operator provides positive shutoff and tamper resistance. Licensed plumbers and pipefitters typically install this valve in process piping, mechanical rooms, and industrial fluid systems where corrosion resistance and pressure integrity are critical.

This valve fits residential and commercial applications where stainless steel construction is required to resist corrosive media, high-temperature fluids, or steam service. The 125 psi steam pressure rating makes it suitable for low-pressure steam lines. The full port design minimizes pressure drop across the valve, which is important in flow-sensitive systems. At 7.28 inches inlet to outlet and 5.71 inches top to inlet center, the valve dimensions should be confirmed against available spool space before installation.

Key Features

• 1000 psi WOG rating with 1500 psi hydrostatic test pressure
• Full port design minimizes flow restriction and pressure drop
• Locking handle operator for positive shutoff and tamper resistance
• PTFE seat, seal, and packing for chemical compatibility across a wide temperature range
• AISI 304 stainless steel stem, handle, nut, and washer with gland nut trim
• Rated for service from -60 to 450 degrees F including 125 psi steam

Compatibility

Designed for inline installation in 3-inch FPT pipe systems. Suitable for water, oil, gas, and low-pressure steam service where ASTM A351 CF8M stainless steel construction is specified.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local mechanical and plumbing codes. Isolate and depressurize the line completely and allow it to cool before removing any existing valve or fitting. Apply appropriate thread sealant to male pipe threads before makeup, following sealant manufacturer guidance for the media being handled. Confirm valve orientation and flow direction before final torque on pipe connections.
