A method of repairing a valve through use of an injection system, the method comprising: attaching a boss to the valve near a gland packing area of the valve, the attaching being performed through friction bonding; operably attaching the boss, an isolation gate, a drill guide gate, an injection gate and an injection pump; opening the injection gate; closing the isolation gate; closing the drill guide gate; sealing the isolation gate, the injection gate and the drill guide gate and joints between the isolation gate, the injection gate and the drill guide from leakage by injecting a sealant from the injection pump into the injection gate; opening the isolation gate; testing the quality of the injection system, including a boss attachment, before drilling into the valve, by injecting the sealant from the injection pump through the isolation gate and into the boss; closing the injection gate; inserting a drill bit into the drill guide; tightening a collet of the drill guide around the drill bit to provide a seal of the drill bit; opening the drill guide gate; through use of a non-sparking pneumatic drill, drilling the drill bit through the sealant and through the boss until the drill bit penetrates a wall of the valve, preventing any hazardous chemicals from escaping into the environment or endangering a repair technician at this stage and during subsequent actions; opening the injection gate; re-pressurizing the injection system to a pressure equal to or greater than the pressure in the valve; withdrawing the drill bit to a point just past the drill guide gate; closing the drill guide gate; injecting sealant into the gland packing area through use of the injection pump; and closing the isolation gate when a sufficient amount of sealant is injected into a valve stem. attaching a boss to the valve near a gland packing area of the valve, the attaching being performed through friction bonding; operably attaching the boss, an isolation gate, a drill guide gate, an injection gate and an injection pump; opening the injection gate; closing the isolation gate; closing the drill guide gate; sealing the isolation gate, the injection gate and the drill guide gate and joints between the isolation gate, the injection gate and the drill guide from leakage by injecting a sealant from the injection pump into the injection gate; opening the isolation gate; testing the quality of the injection system, including a boss attachment, before drilling into the valve, by injecting the sealant from the injection pump through the isolation gate and into the boss; closing the injection gate; inserting a drill bit into the drill guide; tightening a collet of the drill guide around the drill bit to provide a seal of the drill bit; opening the drill guide gate; through use of a non-sparking pneumatic drill, drilling the drill bit through the sealant and through the boss until the drill bit penetrates a wall of the valve, preventing any hazardous chemicals from escaping into the environment or endangering a repair technician at this stage and during subsequent actions; opening the injection gate; re-pressurizing the injection system to a pressure equal to or greater than the pressure in the valve; withdrawing the drill bit to a point just past the drill guide gate; closing the drill guide gate; injecting sealant into the gland packing area through use of the injection pump; and closing the isolation gate when a sufficient amount of sealant is injected into a valve stem.
