There are several methods to control the extending and
retracting speed pneumatic cylinders. We offer Flow Controls, Speed Control
mufflers, and Quick Exhaust Valves to accomplish speed control. Double-acting cylinders
can have both the out and in stroke controlled and you can mix the different
control methods on each port. In reality it is difficult to regulate speed of
air cylinder because of the compressible nature of air. So exact speeds are
not obtainable but you can get sufficient control for prop requirements.
A flow control valve is a needle valve with a check valve
build in it. A needle valve restricts flow in both directions. However flow
control valves allow flow go freely in one direction and restrict it in the
You can connect a flow control valve into a port of a
cylinder in two ways. You can restrict flow out of cylinder (metering out) or
you can restrict flow into the cylinder (metering in). There are reasons to use
one over the other.
When cylinder piston extends, air behind it is compressed
because air can't escape easily. When you tighten the flow control screw,
movement of the piston slows down because air is restricted even further.
Male Connector Push-On with Flow Control
Screw to your cylinder where the air enters (top, bottom,
or both). Simply turn the needle valve to adjust air speed, screw the smaller
jam nut to lock in place
In-Line Flow Control
Controls the speed of a cylinder or restricts air flow.
Simply turn the needle valve to adjust air speed. We offer two styles, one
with push-on’s on both sides and the other with female threads on both sides.
Flow Control with push-on’s. Both sides
have push-to-connect fittings; simply push the tubing into each side.
Flow Control with female threads. Both
sides have female threads. You could use with our Male Connector Push-On
Fittings and then simply push the tubing into each side. Or use with any other
type of fittings for your specific application.
Quick Exhaust Valve
exhaust valves are commonly used to increase the speed of cylinders or for
rapid depressurization of tanks containing compressed air. The displaced air
inside of the cylinder is allowed to exhaust immediately from the Quick Exhaust
Valve rather than having to travel back down the airline and our through the
·3 ports: air in, air out, and quick exhaust
·All ports are threaded female (available in 1/8, 1/4, 1/2 and 3/4
·We recommend that a silencer or muffler be mounted on the outlet.
Or leave open if used for air blasters.
Speed Control Mufflers
The Speed Control Muffler provides infinite metering of
air flow by restricting the
displaced air inside of the cylinder from escaping. The sintered
bronze is encased by an outer metal shroud. With linear adjusting capability,
the speed of the cylinder can be decreased by adjusting the integrated screw.
When optimal exhaust rate is reached, the lockout may be adjusted to prevent
accidental adjustments due to vibration or other means.
