Abstract: A bypass valve and method of utilizing a bypass valve located inside of a tubular or mill that allows one set of equipment to operate, operating a second tool on demand, and then providing a fluid pathway for at least a third device to operate. The bypass valve has a through bore with the restriction. Fluid flows through the restriction at a first rate that is sufficient to operate a measuring while drilling tool. The fluid flow is then increased to a second rate where the restriction causes an increase in pressure within the bypass valve. The increase in pressure allows a packer typically below the bypass valve to be set. Fluid flow is then increased to a third rate causing a further increase in pressure within the bypass valve due to the restriction.
