Detailed Project Report on lpg cylinder valves manufacturing plant

LPG CYLINDER VALVES MANUFACTURING PLANT [3631]
    
Valves are a type of mechanical device that are implemented to regulate flow, pressure, or both, within a system. They an integral aspect of any piping system that requires a fair amount of control. The primary functions of a conventional valve comprise flow control in the form of rate of flow and the direction of flow. Valves are thus used to prevent back flow, and relieving pressure. The various valve types, designs, and models can be functional in specific industrial, commercial, and residential applications. LPG valves may need to be designed especially for maintaining high pressure within the cylinder and to let out the gas at a rate specified and within regulatory permission. These valves are also designed to withstand the possible damage they may take during transportation. An additional cap is often screwed over the valve in order to further reduce the likelihood of gas leakage when the cylinder is not in use. The gas cylinder valve is the primary safety mechanism on a gas cylinder and shall not be tampered with. It is a device used to contain the contents of the cylinder that is under pressure. Cylinder valves are fitted with pressure relief valves of different types (depending on the cylinder) to protect against catastrophic failure of the cylinder valve. Cylinder valves open in an anticlockwise direction and close in a clockwise direction. Valves shall never be opened without a regulator attached. Always open cylinder valves slowly. There two basic types of LP Gas cylinder valves for vapour service, namely, self-closing, clip-on valves and hand wheel operated valves. They can come with or without pressure relief valves depending on local regulations.
