The present invention provides an improved fuel tank isolation valve (). In particular, the invention is directed to provide an improved fuel tank isolation valve () which is normally open for one time delivery condition of the valve to enable refuelling function at the time of vehicle assembly. Said valve () comprises of a valve housing () and a solenoid housing (), wherein the solenoid housing () includes one latch assembly that locks the moving core () in radial or axial direction to provide an intermediate latching position for single operation.

A leak proof, completely sealed solenoid valve, comprising a housinghaving a fluid flow path controlled via an electrically operated mechanism to control a flow; the mechanism comprises metallic coilcoiled around a bobbinsupported by a magnetic bracketwith terminal pinsconnected to the bobbinfor receiving electrical input to facilitate an energized and de-energized state to control the movement of a poppetshaft that obstructs the flow; wherein, the bobbincomprises micro-melting fins, thereby housing over molding creates strong bond between two materials; a permanent weld is created between the bobbinand the housingto prevent internal leakage; and the completely sealed solenoid valve limits emissions and evaporations of the volatile fuel components into and from the valve, and contribute to reliability and robustness of the product by completely sealing the nozzle and housing using laser welding.

The invention relates to a dual path dual purging system and valve assembly for turbo boosted engines. More specifically, the invention provides an integrated valve assembly connected to facilitate the operation of the low flow valve as a pilot valve for the high flow valve and a system to implement it on turbocharged or supercharged engines. The invention relates to a dual path dual purging system with two purge valves connected to facilitate the use of the low flow valve to be operated as a pilot valve for the high flow valve. This smart routing provides pressure compensation for the high flow valve, when the valve is enabled. This decreases the requirement of force for the high flow valve and gives an option to install a smaller cost efficient solenoid valve.
