    The 90° elbow shape allows you to install these valves in tight spaces. They quickly vent exhaust air to the atmosphere or divert it to another place in your system to speed up the movement of air cylinders. Also known as quick exhaust valves.
    NPTF Inlet Thread—NPTF (Dryseal) threads are compatible with NPT threads.
    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.

    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.

    Elbow Air-Exhaust Control Valves with Flow Control

    Image of Product. Front orientation. Contains Annotated. Air-Exhaust Valves. 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 inlet port is for use with plastic or soft metal tubing; insert tubing into the port. A muffler reduces exhaust noise. Also known as quick exhaust valves.
    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.

    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.
