About Flow Control Valves
Also known as cylinder speed controls, flow control valves let you control the extension or retraction speed of your air cylinder. They regulate airflow as it passes from the valve's inlet to its outlet. Air flows freely in the opposite direction.

ASME-Code Fast-Acting Pressure-Relief Valves for Steam
- For Use With: Steam
- Temperature Range: -60° to 400° F
These valves meet ASME Code Section I for use with steam power boilers requiring pressure relief above 15 psi. They spring fully open at the set pressure and remain open until the system pressure is restored below the set pressure. For remote discharge, attach a drain line to the threaded relief port. Valves have a durable bronze body for a long service life.
Swivel test levers rotate 360° around the valve for use in areas with limited clearance.

Pressure-Relief Valves for Air and Inert Gas
- For Use With: Air, Inert Gas
- Specifications Met: ASME BPVC.VIII
- Temperature Range: See table
Unlike valves that release discharge directly, these have a threaded relief port to direct discharge away from your work environment. They spring fully open at the set pressure and remain fully open until the system pressure is restored below the set pressure. All meet ASME Code Section VIII for use with air and inert gas pressure vessels. Body is bronze for durability and a long service life.

Swivel On/Off Valves with Garden Hose Threads
- Valve Type: Ball
- For Use With: Water
- Temperature Range: 35° to 120° F
Keep fluids flowing—these valves twist and turn to prevent your hose from kinking. They connect to your faucet and swivel 360°, which makes it less likely your hose will kink when you move it side to side. Their lever handle is easy to turn, and lets you know if the valve is open or closed at a glance.
Zinc valves have good corrosion resistance. A plastic coating protects your hands by keeping the valve’s surface from getting too hot or cold.
Brass valves are more durable and corrosion resistant than zinc valves.
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.
Add a kink absorber for additional protection to your hose. Connected between the valve and the hose, they prevent kinking from sharp up and down movements.

Flexible-Mount Air Flow Control Valves
A swiveling outlet port allows you to make a connection from any direction. These valves adjust the volume of air exiting an air cylinder (meter out) to control the speed of air-powered equipment. They control flow in one direction as air moves from the inlet to the outlet. Air flows freely in the opposite direction. The valve body has an elbow shape, which allows you to mount them directly to cylinder ports, eliminating additional tubing between the cylinder and valve for better control and consistency than inline valves. Insert plastic or soft metal tubing into the push-to-connect outlet ports.
Flow coefficient (Cv) is a measurement that indicates how much airflow can pass through a valve. When selecting between valves with the same port size, choose the valve with the higher flow coefficient to ensure it provides enough airflow to operate your system.

Corrosion-Resistant Single-Control Two-Direction Air Flow Control Valves
Made of PBT, these plastic valves are more corrosion resistant than valves made of aluminum or nylon. A single dial regulates the speed of airflow in two directions as it enters (meter in) and exits (meter out) equipment, and are often used to control the extension and retraction speed of an air cylinder at the same time. Insert plastic or soft metal tubing into the push-to-connect outlet ports; the outlet ports swivel 360° so you can make a connection from any direction. The elbow shape allows you to mount these valves directly to cylinder ports, eliminating additional tubing between the cylinder and valve for better control and consistency than inline valves.

High-Flow Stainless Steel Steam Traps
Also known as inverted-bucket steam traps, these provide near-continuous discharge to accommodate high condensate levels. They are normally open to release condensate and close immediately when steam enters to prevent energy loss.
Style B attaches to a connector (sold separately) and swivels so it can be positioned both vertically and horizontally.
Swivel Threaded On/Off Valves
Make connections from any direction—the body of these valves swivels 360° for easy installation. Often used in testing and sampling applications, they quickly open and close with a toggle or button.
Toggle-switch valves stay open until you flip them closed. Since they don’t need to be held open, they’re often used to dispense large samples. The toggle’s position shows you if they’re open or closed.
Push-button valves open when you press the button. When released, the button springs back and automatically stops flow. They’re ideal for intermittent use and controlling flow to avoid spills.
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.
