The Smith-Cooper International 8501L series brass gate valve has a non-rising stem, and female National Pipe Taper (NPT) threads on both ends. It has a screwed bonnet, and its brass construction provides corrosion resistance, ductility at high temperatures, and low magnetic permeability. Brass can be connected to copper, brass, plastic, aluminum, and welded steel. The non-rising brass stem stays fixed in place when the gate is raised or lowered, making it suitable for low clearance or underground use. The stem includes PTFE internal packing to help prevent leaking. This valve has a maximum pressure rating of 200 pounds per square inch (gauge) (psig) for water, oil, and gas (WOG). This valve has female NPT threads on both ends for connecting to male pipes with tighter seals than straight threads. Mounted on top of the valve, a manually operated hand wheel activates the inside screw mechanism, which lifts and lowers the gate to start and stop the flow between the connected pipes. This valve meets National Sanitation Foundation (NSF)/American National Standards Institute (ANSI) 61-8 standards for quality assurance, and is certified to California AB1953.
Gate valves control flow in a piping system by lifting a gate out of the path of steam, fluids, or gases. They are designed to block or permit flow, as the vibrations and force of flow repeatedly striking a partly lowered gate can damage the gate and seats. To accommodate different flows and pressure requirements, gates come in four types: solid wedge (appropriate for almost all liquid service), flexible wedge (appropriate for steam service), split wedge (appropriate for normal temperature, non-condensing gas and liquid service, including corrosive service), and parallel disc (appropriate for high and low pressure applications). Hand wheels or levers activate the screw mechanism in the valve’s bonnet, which comes in various designs, to open and close the gate. Union bonnets are preferable for building service piping, threaded-in (or screw-in) bonnets work well for lighter-duty usage, and bolted body-bonnet connections are used primarily in iron multi-turn valves. Most gate valves have either a rising stem, which moves up and down with the gate, or a non-rising stem, which remains fixed in place. When closed, the gate and its seats form tight planar sealing surfaces, ideal for linear liquid flow. Gate valves are used in air, gas, liquid, and steam applications.
Smith-Cooper manufactures a wide variety of pipe fittings and valves. The company is headquartered in Commerce, California, and meets relevant ANSI, ASTM, and International Organization for Standardization (ISO) 9002 standards.

Give it a few minutes to settle in on the pressure.I walked away and forgot about it. The next morning the wife came in saying she was shutting down the system and getting ready to drane the water tank. I asked why, but she was already gone. I walked out and saw the top seal around the valve stem was leaking a good stream, I took a pair of pliers and tighten the stem seal cap and the leak was fixed.Don't walk away after installing, give everything a chance to settle.

It's a valve, for some reason the store are all going to Sharkbites can't use them on incoming water service,

I replaced a gate valve with this product in a vertical application. The quality of this product was very high. I originally went to the local big box store in order to find a suitable product, however none were up to the standard of this valve. Make sure you know the specifics of the valves you are looking for (ie. lead free, type of turn). I will update this review if there are any changes in the valve over time.

Excellent product, well built, sturdy, works freely. Will buy some later.

Castings and slide of gate inside the valve are excellent. Will certainly last for many years.Purchased 2 of these valves and neither one shuts off 100%. Tiny trickle of water through the valve.In my situation this is not a problem. After the 2" is split in different runs the ball valves in individual linesAre used as shut offs.
