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.

Connectors for Rigid PVC Conduit
Join pieces of PVC Schedule 40 or Schedule 80 conduit. These connectors are lightweight, corrosion resistant, and UV light resistant for outdoor use. They can be buried or encased in concrete. PVC cement is required (not included) to secure the connection.
Adjustable-angle elbow connectors also attach conduit to a knockout when you take off the removable ends to access the threaded connections.

Gas Chimney Vents and Fittings
For use with gas-fired equipment, such as boilers and furnaces, these vent pipes and fittings withstand temperatures up to 400° F. Also known as type B gas vents.
To join pipes and connectors, insert a male end into a female end and secure with the included locking band.

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.

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.
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.
