What is the function of the discharge valve in an air receiver?

The discharge valve in an air receiver is primarily responsible for releasing compressed air from the receiver into the distribution system or for use in tools and equipment. When the system requires air, the discharge valve opens to allow the pressurized air to flow out, thus enabling the application of compressed air wherever it is needed. This function is critical for the operation of pneumatic systems, as it ensures that air can be efficiently delivered or cycled according to demand.

Additionally, the design of the discharge valve also often includes safety considerations, as it can help to manage the pressure within the receiver, preventing over-pressurization. By allowing the controlled release of air, the discharge valve plays a vital role in maintaining the balance and efficiency of a compressed air system. This functionality underscores its importance in the overall operation and maintenance of air compressors and receivers.
