About Actuated On/Off Valves

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.

With DIN Connection

With Wire Leads

These solenoid valves operate on electricity to automatically start and stop flow. The actuator is directly mounted to the valve body to minimize movement and reduce wear.

Normally closed valves are closed unless actuated. Normally open valves are open unless actuated.

316 and 316L stainless steel valves are more corrosion resistant than brass and bronze valves.

Zero pressure drop valves don’t require a minimum pressure drop between the inlet and outlet for operation. Pressure drop assisted valves require a minimum pressure drop between the inlet and the outlet for operation; the upstream pressure must be greater than the downstream pressure.

All IP- or NEMA-rated valves stand up to dust and washdowns. IP69 valves resist high-temperature, high-pressure washdowns. NEMA 4X valves withstand corrosive liquid.

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.

Self-Closing Drum Faucets

Push or pull the faucet handle to open; release the handle and the faucet automatically shuts off. These faucets are primarily used on drums, but can also be used on tanks, carboys, and other containers.

In case of fire, faucets with a flame arrester prevent flashback into the drum.

Style D can rotate to position the spout downward without damaging threads.

Style E can be used with a thread adapter to connect to a drum with a 2” Buttress or Mauser thread.

Air-Operated Air Flow Control Valves with Safety Shut-Off

Protect air-powered equipment in emergency shut-off situations—when system pressure drops, the air pilot signal stops and these valves automatically close to stop cylinder motion, even at a mid-stroke. They control the speed of air-powered equipment by adjusting the volume of airflow. A pressure-release button allows you to exhaust any trapped air pressure from the system after shut down. Install them in pairs on cylinder exhaust ports, and use tee connectors (not included) to direct exhaust air from the cylinder to the air pilot of the opposite valve, and to connect valves to a directional control valve. The elbow shape allows you to mount them directly to cylinder ports, eliminating additional tubing or piping between the cylinder and valve for better control and consistency than inline valves.

Two direction valves control airflow 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. One direction valves control flow as air exits the cylinder (meter out) and moves from the inlet to the outlet.

Valves with push-to-connect ports are for use with plastic or soft metal tubing. Insert tubing into the port.

Flow coefficient (Cv) is a measurement that indicates how much airflow can pass through a valve.
