FM-approved, these valves are often used to isolate sections of your facility’s water supply for fire suppression and protection. They bolt to flanges for easier installation and removal than threaded or weld-on valves. This makes them a great choice if you have to clean and maintain your line frequently. Also known as gate valves, they open and close gradually to prevent sudden starts and stops of flow that could damage your system. Epoxy coated, these valves resist corrosion. They’re bright red, so they’re easy to identify as fire valves.

Their rubber-coated gate, also known as a resilient wedge, compresses against the valve for a long-lasting, leakproof seal. It seals tightly even if you install these valves vertically, or if there’s low back pressure. For easy disassembly during maintenance, they have a flanged stem housing that bolts in place. However, the housing makes these valves heavier and larger than valves with a threaded or welded stem housing.

Valves with a wheel handle open and close with multiple turns for controlled, shock-resistant flow. Wrench-operated valves are the best choice for hard-to-reach locations, such as underground or inside a manhole. Operate them from a distance with a valve wrench. You can also open and close them with a fire indicator post.

Valves with a nonrising stem keep the handle in the same position whether they’re open or closed. They're often used underground and in low-clearance locations. Valves with a rising stem lift the handle as they open and lower it as they close. At a glance, you can see if flow is on or off. The stem is isolated from what’s flowing through your line, giving these valves a longer lifespan than valves with a nonrising stem. This makes them good for critical lines and lines that need to be opened and closed frequently.

Ductile iron valves are stronger and more durable than cast iron valves. They’ll handle greater pressure changes without cracking.

Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.

These valves have a sharp gate that slices through thick slurries, wastewater, dry bulk solids, and other materials that would clog other gradual on/off valves. They bolt to flanges and gradually open and close to prevent system damage from suddenly starting and stopping flow. The wheel handle opens and closes the valve with multiple turns, providing controlled, shock-resistant flow. The rising stem lifts as the valve opens and lowers as the valve closes to provide a visual indication of whether flow is on or off. The stem is isolated from the process media for a long service life.

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. If the bellows fail, a reinforced seal—also known as a backseat seal—minimizes the risk of leakage. Ideal for heating and steam service applications, they maintain their seal even as the temperature swings. Plus, the stem housing is welded to make sure nothing leaks out. Also known as gate valves, these valves open and close gradually with multiple turns of the wheel handle to prevent sudden starts and stops. They bolt onto flanges, so they’re easier to install and remove for cleaning and repairs than threaded or weld-on valves.

The handle raises as these valves open and lowers as they close. At a glance, you can see if flow is on or off. The stem is isolated from what’s flowing through your line, giving these valves a longer lifespan than valves with a nonrising stem.

A rubber-coated gate, also known as a resilient wedge, compresses against the valve seat to give these valves a tight, leakproof seal. They shut tight even when they’re installed vertically, have low back pressure, or the liquid contains solids and debris. Often called gate valves, they open and close gradually to prevent sudden starts and stops that can damage your system. Since they bolt onto flanges, they’re easier to install and remove than threaded and weld-on valves. This makes them a good choice for lines that need frequent cleaning and maintenance. You can use them in lines for water supply, reclamation, and wastewater treatment—they meet AWWA (American Water Works Association) specifications. To protect against corrosion, the body is coated with epoxy.

The stem is nonrising, so it stays in the same position whether the valve is open or closed. They’re often used in low-clearance spots. Their flanged stem housing bolts in place to make them easy to take apart for repairs. However, the flanged stem housing makes these valves heavier and larger than valves with threaded or welded stem housings.

Wrench-operated valves work well in hard-to-reach places, such as underground or the bottom of manholes, since you can turn the flow on or off from a distance. Open and close them with T-handle valve wrenches.

Ductile iron valves are stronger and more durable than cast iron valves, handling greater pressure changes without cracking.
