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.

Also known as butterfly valves, these bolt to flanges for adjusting and regulating flow in flanged pipelines.

Wafer valves must be sandwiched between two flanges; they have tabs or unthreaded holes to help align the valve between the flanges.

Lug valves can be sandwiched between two flanges or bolted directly to a single flange for servicing one end of the pipeline without depressurizing the other side. They have threaded flange holes with a hole pattern that matches ANSI flanges of the same pipe size.

Wheel handles open and close with multiple turns, providing fully adjustable flow.

Bolt these valves to ANSI flanges. They open to allow flow in one direction and close when flow stops or reverses. All have a removable cap that provides easy access to internal components for maintenance.
