Overview
The Midland Industries 940132 is a 1/2 in. full-port brass gate valve with Female NPT x Female NPT ends and a standard wedge handle. Its non-rising stem, screw-in bonnet, and solid wedge disc give a straight-through, full-bore flow path with tight metal-to-metal shutoff, making it a solid choice for on/off isolation duty on water, oil, and gas lines (including diesel fuel) rated to 200 PSI WOG.

Typical Applications
Main-line and branch isolation where a valve stays fully open or fully closed for long periods - water service, fuel and oil lines, irrigation, and equipment shutoff. Gate valves are built for isolation, not throttling; for frequent flow control, use a ball valve instead (see the comparison guide below). Not for potable drinking water.

Frequently Asked Questions
What is a gate valve best used for?
Full on/off isolation. The full-port wedge gives unrestricted flow when open, but gate valves are not meant for throttling or frequent cycling.
Gate valve or ball valve?
Use a gate valve for set-and-forget isolation; use a ball valve for frequent operation and faster quarter-turn shutoff. See our comparison guide above.
What is the pressure rating?
200 PSI WOG (cold water, oil, gas), with a 32 to 320 °F service range.
Can I use it on drinking water?
No. This valve contains lead and is not certified for potable water. Choose a lead-free valve certified to NSF/ANSI 61.
