High-Flow Mufflers | McMaster-Carr

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.

Commonly used with high-flow, air-powered equipment, such as diaphragm pumps and valves, these mufflers reduce noise and filter exhaust fumes without restricting flow.

Exhaust Filters/Mufflers for Dry High-Vacuum Pumps

Purify exhaust fumes while silencing the noise from your oil-free high-vacuum pumps. With quick-clamp (KF) connections, these filters/mufflers connect to exhaust ports with a clamp and ring (sold separately). Mount them vertically or horizontally. All are carbon steel with a powder-coated finish for corrosion resistance.

Air-Exhaust Flow Control Valves

Dial Flow Adjustment

Slotted Screw Flow Adjustment

Thumb Screw Flow Adjustment

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.

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.

Elbow Air-Exhaust Control Valves with Flow Control

Control the flow of exhaust air while also regulating the exhaust air speed. These valves dump exhaust air to the atmosphere without routing it back through a directional control valve. They control flow in one direction as air flows from the inlet to the outlet, and adjust the volume of exhaust air exiting an air cylinder (meter out) to control its speed. Air flows freely in the opposite direction. They have a 90° elbow shape that allows you to install them in tight spaces. The push-to-connect outlet ports are for use with plastic or soft metal tubing; insert tubing into the ports. A muffler reduces exhaust noise. Also known as quick exhaust valves.
