More Information
Summary:A manual reset actuator includes a main drain, a diaphragm release aperture fluidly coupled to a flow control valve, an upper chamber, a control port, a control orifice, an upper chamber supply orifice, and a sealing assembly, which includes a button, and a plunger. A pressure in the upper chamber exerts a downward force on the plunger. A spring exerts an upward force on the plunger. The fluid in the upper chamber is released via the control orifice, which lowers the pressure in the upper chamber, decreasing the downward force exerted on the plunger. When the downward force is less than the upward force, the spring forces the plunger upwards into an open configuration, which unseals the diaphragm release aperture. When the upward force is less than the downward force, the plunger remains in a closed configuration, which keeps the diaphragm release aperture sealed.
