Available in smaller pipe sizes than other solenoid flow-adjustment valves, these are often used with gas controllers and analytical instrumentation. They adjust and regulate flow based on the intensity of the electrical signal into the valve and are often integrated into PLC systems for automatic control over the valve position based on system conditions. They are normally closed unless actuated. Valves don’t require a pressure drop for operation. The actuator is directly mounted to the valve body to minimize movement and reduce wear.

Also known as flush-face couplings, the plugs and sockets have a flat face, which allows them to mate close against each other, reducing fluid loss when connecting and disconnecting the line. A complete coupling consists of a plug and a socket (both sold separately) that connect and disconnect quickly. Use them when you need frequent access to a line. All of the International Standard ISO Minimal-Spill quick-disconnect plugs are compatible with any of the International Standard ISO Minimal-Spill quick-disconnect sockets of the same coupling size, regardless of the pipe size. Couplings are compatible with ISO 16028 Parker FEM, ISO 16028 Perfecting HT, and ISO 16028 Snap-Tite 74 couplings. Also known as double shut-off couplings, the plugs and sockets both have a shut-off valve that stops the flow when the coupling is separated. They are zinc-plated steel, which has excellent strength and durability and fair corrosion resistance.

Plugs are also known as nipples.

Sockets are push-to-connect style. To connect, push the plug into the socket until you hear a click. To disconnect, slide the sleeve on the socket forward until the plug ejects.

Note: To ensure a correct fit, make sure that the plug and socket have the same coupling size. Pressure ratings are given for static (constant) pressure conditions.

Warning: Never attempt to connect or disconnect couplings when operating at maximum pressure. Stop the flow before you disconnect the line.

Unlike other manifolds, which have an inlet on either end, these have one inlet on the opposite side from the outlets. This design allows fluid or air to follow a straight path, improving flow through your system. It also frees up the ends of the manifold, so you can mount it in corners and in narrow spaces. Manifolds are also known as headers. They have mounting holes, so you can mount from the top or side.

Anodized aluminum manifolds are the industry standard for the most common types of applications. They are lighter in weight than other metal manifolds and have good corrosion resistance. These manifolds are anodized for a black finish.

Use a plug (sold separately) to close off any unused inlets and outlets.

Stop the reverse flow of gas in your regulator. Check valves do not stop flashbacks.

Stop the reverse flow of gas in your torch. Check valves do not stop flashbacks.

Attach these arresters to the outlet connection of a regulator on a torch that cuts steel up to 11" thick. Arresters extinguish flames and have a check valve to stop reverse gas flow. They are reusable; resetting is not required after flashback.

Arresters with right-hand threads are for use with oxygen; arresters with left-hand threads are for use with acetylene, hydrogen, and propane.
