LPG Cylinder Valve V-5A

Gas cylinder valve is a valve that is mounted on a gas cylinder to control gas on and off and flow. Also known as the "bottle valve." Gas cylinders of different media generally use cylinder valves of different structures. Their common features are mostly manual, simple structure, small size, high strength, working temperature of -40 ~ 60 ° C, the material can adapt to the physical and chemical properties of the medium and commonly used copper, and some have a safety relief device, such as Use stretch or shear rupture discs and safety plugs made of fusible alloys. The gas cylinder valve is divided into a flap type, a shaft type, a needle form, a rubber joint type and a diaphragm type according to the structure. Their range of motion refers to the range of pressure for compressed gas and to the range of temperature for liquefied gas. [1] 
In order to ensure the safety of use, it is stipulated that the spiral direction of the outlet of the cylinder valve uses a left-hand thread for the combustible gas and a right-hand thread for the non-combustible gas. The cap should have good impact resistance. Sealing materials for oxygen and strong oxidizing gas bottle valves, and hand wheels for liquefied petroleum gas cylinder valves must use materials with good flame retardancy. The main performance test items before leaving the factory are air tightness test and safety device action test; the valve body strength test and the opening and closing torque, opening range, vibration resistance, humidity resistance, high temperature resistance (or low temperature) and vacuum test should be carried out before finalizing and appraising.ect.
