J91W - p - 40 64 p - 160 p - 320 p type stainless steel ferrule needle valve and ball valve difference is bigger, we can distinguish from the function to go up and ball valve and J91W - p - 40 64 p - 160 p - 320 p type stainless steel ferrule needle valve different effects, from ball Industrial Valves and J91W - p - 40 64 p - 160 p - 320 p type stainless steel ferrule needle valve structures. 【 Functional difference between 】 J91W - p - 40 64 p - 160 p - 320 p stainless steel card type 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 valve and J91W - p - 40 64 p - 160 p - 320 p type stainless steel ferrule needle valve difference is bigger, 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 】 J91W - p - 40 64 p - 160 p - 320 p type stainless steel ferrule needle valve' Summary 】 J91W - p - 40 64 p - 160 p - 320 p type stainless steel ferrule 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, whether at design time, or in the purchase, must be in strict accordance with the relevant technical requirements.
