It resets automatically once cooled below the threshold. Ideal for applications with low coolant flow, interrupted cooling water supply, or abnormal high sample temperatures.\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOperation\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eWINNING® HST (High Sample Temperature) safety shutoff valve is used to sense the sample temperature after the sample cooler. The sample passes through this normally open valve whenever the sample temperature is below the valve setpoint. If the sample temperature exceeds the valve setpoint, the HST closes to protect expensive and delicate analyzers and other instruments from overtemperature damage. \u003cbr\u003eWhen the HST cools* below the setpoint, it will automatically reset open again. Low coolant flow or total loss of cooling water or unusually high sample temperatures are typical reasons why the HST self-operating protective device should be considered.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eApplication\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eExcessively hot samples can cause damage to expensive and sensitive hardware and electronics. For process analyzers and similar instrumentation, it is important to assure that the process samples fluids are always below the maximum allowable temperature for such instruments. Sample coolers are commonly used to reduce sample temperatures to the acceptable limits. In the event of a loss of cooling fluid to the sample cooler, or if the desired sample temperature is exceeded for any reason, the HST valve will close to prevent equipment damage. \u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0647\/3383\/9531\/files\/HSTV_1.png?v=1768811148\" alt=\"\" width=\"431\" height=\"97\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/p\u003e\n\u003ctable width=\"100%\" style=\"width: 61.194%;\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 60.4179%; text-align: center;\"\u003eProduct Name\u003c\/td\u003e\n\u003ctd style=\"width: 39.0311%; text-align: center;\"\u003eHST\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 60.4179%; text-align: center;\"\u003eModel\u003c\/td\u003e\n\u003ctd style=\"width: 39.0311%; text-align: center;\"\u003eFP17\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 60.4179%; text-align: center;\"\u003ePort Size\u003c\/td\u003e\n\u003ctd style=\"width: 39.0311%; text-align: center;\"\u003eNPTF 1\/2''\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 60.4179%; text-align: center;\"\u003eBrand Name\u003c\/td\u003e\n\u003ctd style=\"width: 39.0311%; text-align: center;\"\u003eWiinning\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 60.4179%; text-align: center;\"\u003eBody Material\u003c\/td\u003e\n\u003ctd style=\"width: 39.0311%; text-align: center;\"\u003eSS316\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 60.4179%; text-align: center;\"\u003eMaximum Temp(℃)\u003c\/td\u003e\n\u003ctd style=\"width: 39.0311%; text-align: center;\"\u003e+130\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 60.4179%; text-align: center;\"\u003eMaximum Pressure(MPa)\u003c\/td\u003e\n\u003ctd style=\"width: 39.0311%; text-align: center;\"\u003e20MPa\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 60.4179%; text-align: center;\"\u003eFlow Rate(Cv)\u003c\/td\u003e\n\u003ctd style=\"width: 39.0311%; text-align: center;\"\u003e0.07\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 60.4179%; text-align: center;\"\u003eDimensions(mm)\u003c\/td\u003e\n\u003ctd style=\"width: 39.0311%; text-align: center;\"\u003eφ35*81\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 60.4179%; text-align: center;\"\u003eNet Weight(g)\u003c\/td\u003e\n\u003ctd style=\"width: 39.0311%; text-align: center;\"\u003e489.3\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNote\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eStandard Temperature \"XXX\" Available: 100°F, 105°F, 115°F, 130°F, 140°F.
