Side pocket mandrel with improved orienting means

A control valve for a passageway in which the valve is reciprocated toward and away from its seat by pressure within a pressure dome and pressure exteriorly of the valve housing and in which reciprocation is controlled by a J-slot capable of latching the valve in open position while being run and releasing the valve for reciprocation after being landed in the well together with a frangible disc which may be ruptured to permit flow past the valve member; said valve being used to control flow through a H mandrel in a pumpdown system.
