Product Summary

2-way pilot operated diaphragm valve moves fluids using a two-part cycle. In the first part, the diaphragm is pulled away from the input/output valves so that the volume of the chamber increases. This increase in volume results in a decrease in pressure within the chamber relative to the input and output, creating a vacuum effect that draws fluid in. Check valves on the input and output connections ensure that fluid can only enter the chamber through the input connection.

2-way pilot operated diaphragm valve are used to heat buildings in the cooler months, but they also are used for cooling during warmer periods and, in the case of air-to-water systems, the system is also used for the production of hot water. The air source heat pump is considered to operate at 300-400 percent efficiency, meaning that it consumes one-third to one-fourth of the electrical energy used by typical electric heating units to produce the same amount of heat. This allows diaphragm pumps to be used in anything from heavy industrial applications to artificial hearts. There are two primary types of actuators for diaphragm pumps. The first utilizes pressured air or fluid to expand or contract the diaphragm. An increase in the pressure on the actuator side of the pump pushes the diaphragm into the chamber, increasing the pressure on the fluid within the chamber and forcing it through the output.

2-way pilot operated diaphragm valve utilizes pressured air or fluid to expand or contract the diaphragm. An increase in the pressure on the actuator side of the pump pushes the diaphragm into the chamber, increasing the pressure on the fluid within the chamber and forcing it through the output. Air lift pumps can be appropriate for waste water treatment, archeological research, and aquaculture where low discharge pressures are required. An air lift pump installation typically consists of a vertical discharge or educator pipe submerged in the body of water to be pumped.
