A42H, A42Y spring full enclosed type relief valve and ball valve difference is bigger, we can distinguish from the function to go up and ball valve and A42H, A42Y spring all rev. Enclosed the different function of the relief Industrial Valves, and all A42H, A42Y spring from ball valve and rev. Enclosed safety valve structure up to distinguish. 【 Functional difference between 】 A42Y spring and enclosed all the relief valve is suitable for the working temperature of 300 ℃ or less medium such as air, gas, liquid equipment and piping. A42Y - P type and A42Y - R type is suitable for the working temperature of 200 ℃ or less corrosive medium of equipment and piping, as the overpressure protection device. - The 94 series. ≥6. - The 94 series. Ball valve and A42H, A42Y spring all rev difference is bigger, enclosed the relief valve ball valve ( 球阀) Opening and closing is a sphere, driven by the valve stem, and for ball valve axis rotate 90 & deg; Open or closed. Can also be used on regulation and control of fluid, mainly used for cutting in line, distribution, and change the flow direction of medium, good sealing, convenient operation, opening and closing fast, simple structure, small volume, small resistance, light weight, etc. 【 Physical difference between 】 A42H, A42Y spring full rev closed valve ball' Summary 】 A42H, A42Y spring full enclosed type relief valve and ball valve and the difference function, are quite different in application, in the selection of a certain need to pay special attention to diameter, pressure, material and use of media, whether at design time, or in the purchase, must be in strict accordance with the relevant technical requirements.
