Compact High-Flow Mufflers

A small hex size makes these high-flow mufflers a good fit for cramped spaces. Commonly used with high-flow, air-powered equipment, such as diaphragm pumps and valves, they reduce noise and filter exhaust fumes without restricting flow.

Air-Exhaust Flow Control Valves


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 exhaust to the atmosphere and include a muffler to reduce the exhaust noise.

Flow Coefficient (Cv)—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.

Right-Angle-Shaft Air-Powered Gearmotors

Use these right-angle gearmotors where space is at a premium. They transmit motion at a 90° angle from the motor, so they’re positioned alongside your application when mounted. A motor and speed reducer in one, gearmotors slow speed while increasing torque. They come with a muffler to reduce noise and filter exhaust air.
