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.

High-Noise-Reducing Mufflers
Install these mufflers in air-powered drills and other loud equipment. They filter exhaust fumes and reduce noise by 30-35 dB, a reduction that's equivalent to putting in earplugs.
Mufflers with pipe connections thread into NPT or metric threaded exhaust ports.

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 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.
