Survivor Control Valve

The Valtek Survivor control valve is a unique severe service control valve specifically designed for use in the harshest erosion, corrosion and flashing applications. Survivor’s unique design allows a wide variety of materials to meet virtually every need. For erosive applications, such as abrasive slurry, the Survivor is available with ceramic trim for maximum life in services that would quickly erode any other material. For corrosive applications, the Survivor offers a wide range of material options from stainless steels to titanium.

The sweep angle design allows the process fluid to flow cleanly, without sharp turns or stagnant points. The unique design of the Survivor directs the energy of flashing process fluids away from critical equipment.

Unlike competing erosive service valves, the Valtek Survivor control valve offers a unique wiper ring design, which provides longer packing life by cleaning the stem and protecting the packing from the harmful effects of the fluid. The exceptionally deep packing box prevents the fluid from contacting the upper guide and provides an extensive variety of packing configurations. Increased flow and superior erosion resistance are realized through the use of a clamped seat design. The clamped seat eliminates both seat retainers and cage guiding.

The Valtek Survivor provides the same high performance, reliable service and simplified maintenance as the Valtek Mark One control valve by incorporating many of the time proven features of the Mark One. These features include such things as top entry for ease of maintenance, heavy-duty double top stem guiding for reliability and high-thrust actuation for superior control.

The Valtek Survivor control valve has proven effective in erosive slurry applications where competitor’s valves have lasted only days.
