A shut-off valve apparatus has a valve body and a valve member coupled to the valve body. The valve member is movable between a first position blocking material flow through the valve body and a second position permitting material flow through the valve body. A pneumatic actuator receives pressurized air to move the valve member from the first position to the second position. A pneumatic exhaust controller controls the flow of pressurized air into and out of the pneumatic actuator.

Shut-off valve apparatus

A pneumatic exhaust controller for use with a source of pressurized air comprises a manifold having a first portal coupled to the source of pressurized air, a second portal, and an exhaust portal. Two manifold embodiments are disclosed. Two regulator embodiments that operate to close the exhaust portal in response to pressurized air from the air source being communicated through the first portal and that operate to pass pressurized air from the pressurized air source to the second portal are disclosed. The regulators are situated in chambers of respective manifolds. A solenoid valve is coupled to each of the manifolds and is operable to block and unblock pneumatic communication between the respective first portal and the associated second and exhaust portals.
