Stimuli are signals that trigger the senses. Receptors detect the stimuli and neurons send the signals to the brain where they're interpreted. Each sense organ includes receptors that capture relevant stimuli for transmission to the brain. The receptors in the skin are mechanoreceptors and thermoreceptors.
AWWA Butterfly valves are quick opening valves that consist of a metal circular disc or vane with its pivot axes at right angles to the direction of flow in the pipe, which when rotated on a shaft, seals against seats in the valve body. They are normally used as throttling valves to control flow.
- Force on the upstream part of a butterfly valve or valve seat. - A support typically used in conjunction with butterfly valves to hold the revolving shaft in its appropriate position. - A solid plate-like fitting used to seal a flanged end pipe's end. - The part of a valve that connects the body to the valve actuator.
