Autoclave Engineers超低温针阀 -253°C至649°C
Autoclave Engineers Extreme Temperature Needle Valve

HT，LT&PV系列耐高温针阀至60000 psi（4137 bar）
HT, LT & PV Series Severe Temperature Needle valves to 60,000 psi (4137 bar)

自1945年以来，Parker Autoclave Engineers设计和制造了高品质的阀门、配件和管道。Parker Autoclave Engineers的HT、LT和PV系列阀门用于-423°F至1200°F（-253°C至649°C）和60000 psi（4137bar）的操作条件。这些阀门用于工艺温度极高和极低时，防止使用标准设计阀门。Since 1945 Parker Autoclave Engineers has designed and built premium quality valves, fittings and tubing. Parker Autoclave Engineers HT, LT and PV series valves are used in operating conditions from -423°F to 1200°F (-253°C to 649°C) and up to 60,000 psi (4137bar). These valves are used where extreme high and low process temperatures prevent the use of standard design valves.

Parker Autoclave Engineers极端温度阀门是为极端温度的应用而设计的。高温和低温阀门设计有一个扩展外壳，从工艺中移除组件，使阀门在这些温度下运行。PV阀门是为电力工业设计的一种更经济的高温阀门。这些阀门由一整套配件、管道和附件组成。Parker Autoclave Engineers extreme temperature valves are designed for applications in extreme temperatures. The HT and LT valves are designed with an extended housing removing the pack from the process allowing the valve to operate at these temperatures. The PV valves are a more economic high temperature designed for the power industry. These valves are complemented by a complete line of fittings, tubing and accessories.
