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.

Mufflers
Use these mufflers with air-powered tools, valves, and cylinders to reduce noise and filter exhaust fumes.
Styles C, K, and M have a slotted drive for installation with a screwdriver.
Styles D and E have a rubber O-ring for extra protection against leaks.
Styles P, Q, and R have a tube stem that slides into tube fittings and collets to decrease noise from manifolds.
Style S has a barbed fitting that slides into soft tubing, such as PVC, latex rubber, and silicone.
Style T has a push-to-connect fitting that connects to firm tubing, such as nylon, polyurethane, and FEP.
Brass, bronze, and copper mufflers offer good corrosion resistance.

Flow-Control Mufflers
Adjust the flow by turning the screw. Use these mufflers with air-powered tools and cylinders to reduce noise and filter exhaust fumes.
For mufflers with an external hex drive, twist the screw and then tighten the hex nut with a wrench to secure. These mufflers are more secure than those with a thumb screw.
For mufflers with a thumb screw, twist the screw and friction secures them in place—no need to use a wrench. Often used in valve exhaust ports, these mufflers are not as secure as those with a nut.
Brass, bronze, and nylon mufflers offer good corrosion resistance.

Clog-Resistant Mufflers
Female
Fitting
Replace your muffler less often—these have a filter design that stays clean longer than porous mufflers. They’re often used in air-powered circuits to reduce noise and filter exhaust fumes.

Air-Exhaust Flow Control Valves
Install these valves in the exhaust ports of air directional control valves to control exhaust air speed without needing access to your cylinder. They control flow in one direction as air moves from the inlet to the exhaust port (meter out). Air flows freely in the opposite direction. Valves exhaust to the atmosphere and include a muffler to reduce the exhaust noise.
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.

Made-to-Order Air-Operated Air-Exhaust Control Valves
When these valves receive an air signal, they quickly dump exhaust air to the atmosphere without routing it back through a directional control valve to speed up the movement of equipment. They're often used with air compressors that require continuous operation. A muffler reduces exhaust noise. Also known as quick exhaust valves.
To Order: Specify minimum pressure and maximum pressure from the ranges listed. The difference between the minimum pressure and maximum pressure must be at least 10 psi, but no more than 30 psi.
