The Copes-Vulcan Model F100-40 Sampling Valve was developed to provide positive shutoff and reliable operation for both sampling and containment isolation applications in nuclear power plants.

Such high-pressure water, steam and gas applications demand exceptional seat tightness. The Copes-Vulcan design incorporates a high-thrust actuator with thru-hardened trim components to ensure better than ANSI B16.104 Class V leakage at 2500 psid (17,255 kPa).
