J94W - p - 40 64 p - 160 p - Type 320 p card set of Angle of needle valve and ball valve difference is bigger, we can distinguish from the function to go up and ball valve and J94W - p - 40 64 p - 160 p - 320 p card type Angle of needle valve set of different effects, from ball valve and J94W - p - 40 64 p - 160 p - 320 p type card set of Angle of needle valve structures. 【 Functional difference between 】 J94W - p - 40 64 p - 160 p - 320 p card type Angle of needle valve is set by the card sleeve connection, applies to oil, water, gas and other non corrosive or corrosive medium, suitable for - 29℃～+440℃ - 70℃～- 240℃ ≤540℃ ≤570℃。 Than other types of valves, high pressure welding of stainless steel needle valve type has better sealing performance and the ability to tolerate stress, generally used for small flow high pressure gas or liquid medium sealing, the most appropriate and cooperate with pressure gauge. Ball Industrial Valves and J94W - p - 40 64 p - 160 p - 320 p type card set of Angle of needle valve difference is bigger, ball valve, 球阀) Opening and closing is a sphere, driven by the valve stem, and for ball Industrial Valves 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 】 J94W - p - 40 64 p - 160 p - 320 p card set of Angle type needle valve' Summary 】 J94W - p - 40 64 p - 160 p - 320 p type card set of Angle of needle valve and ball valve difference on and use 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, no matter when the design, or in the purchase, must be in strict accordance with the relevant technical requirements.
