Copes-Vulcan’s new Model F100-40 Sampling valve has been developed to provide positive shutoff 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 allowing better than ANSI B16.104 Class V leakage at 2500psid. The Copes-Vulcan Model F100-40 valve can solve leakage problems in critical applications by offering positive shutoff and radiation resistant materials. Piping supports and restraints are eliminated by the actuator wall-mounting of the entire valve.
