Designed for use in refineries and other demanding environments, these valves have a durable body that can withstand nearly twice the pressure of other gradual on/off valves.

Maintain and repair these valves while they’re still inline—you can disassemble the stem so there's no need to unthread the pipe connections. Also known as gate valves, they open and close gradually to prevent sudden starts and stops.

Easier to install and remove than threaded or weld-on valves, these valves bolt to flanges. They open and close gradually, preventing system damage from sudden starts and stops in flow.

With a forged steel body and bolted construction, these valves can withstand nearly 10 times the pressure of other socket-connect gradual valves.

Use these valves in general purpose applications, such as those with water, oil, air, and inert gas.

For installation through thick insulation, these valves have an extra-long stem.

With a three-piece bolted body that disassembles for access to internal components, you can clean and repair these valves without unthreading them from your line.

For fast installation and removal from pipelines, these valves have a union fitting that disassembles into multiple pieces. They’re for use with water, oil, air, inert gas, and steam.

Bolt these valves to ANSI flanges.

Weld these valves to unthreaded metal pipe for a permanent, flush connection that permits smooth flow through a line. Use with water, oil, inert gas, and steam.

Often used for oxygen service and other high-purity applications, these valves come cleaned and bagged. Insert unthreaded pipe into the socket ends and weld to create a permanent, leak-tight connection. For easy maintenance, they have a three-piece bolted body that disassembles inline so you can access internal components without removing welded connections.

Clean and repair these valves without removing them from your line. They have a three-piece bolted body that disassembles for access to internal components. For extra gripping power and a strong seal, these valves have Yor-Lok fittings with two sleeves that bite into tubing as you tighten the nut. All are compatible with Swagelok®, Let-Lok, and Parker A-Lok fittings.

Install these valves in lines that require frequent maintenance or cleaning. They give you a leak-tight, permanent solder connection to your tubing with the ease of a union fitting to install them without disrupting your line.

Service these valves without cutting soldered connections. The three-piece bolted body can be disassembled inline for easy access to internal components. Use with water, oil, inert gas, and steam.

To create a tight seal in vacuum conditions higher than 29.9” Hg, these valves have ultra-high-vacuum tube fitting connections, which are also known as KF, QF, and NW fittings. They are often used in applications such as vacuum coating and heat treating, leak testing, and analyzing gases.

Slide copper pipe into the solder-connect fittings on these valves and weld for a strong, permanent connection.

With a slimmer motor than other motor-driven valves, these fit in tight spots.

Also known as butterfly valves.

Use air pressure to automatically control the flow of liquids in sanitary environments, such as food and beverage processing plants.

With a ball-valve design, these valves can handle three times the flow of butterfly valves.

Also known as diaphragm valves, these have a diaphragm that can handle dirty liquid, slurries, and abrasive media without damage.

A compact, lightweight actuator and an angular body allow you to install these valves in any mounting orientation.

Also known as diaphragm valves, these have a diaphragm that can handle dirty liquid, slurries, and abrasive media without damage.

Valves are for use with water, oil, air, inert gas, and steam. They gradually open and close to adjust and regulate flow.

Insert unthreaded pipe into the socket ends and weld to create a permanent, leak-tight connection. These valves are for use with water, oil, air, inert gas, and steam. They gradually open and close to adjust and regulate flow.

For extra gripping power and a strong seal, these valves have Yor-Lok fittings with two sleeves that bite into tubing as you tighten the nut. All are compatible with Swagelok®, Let-Lok, and Parker A-Lok fittings. Turn the handle to adjust flow in small increments for metering, sampling, and other applications requiring fine flow control.

To withstand a maximum steam pressure of at least 4,800 psi @ 355° F in applications such as petroleum refineries, these valves are machined from a single piece of metal for seamless construction. Turn the handle to adjust flow in small increments for metering, sampling, and other applications requiring fine flow control.

Rated for nearly twice the maximum temperature of standard threaded precision flow-adjustment valves, these can handle up to 700° F. They’re for use with water, oil, air, and inert gas. Turn the handle to adjust flow in small increments for metering, sampling, and other applications requiring fine flow control.
