Product Summary

Double disc gate valve is available off-the-self or custom manufactured in Carbon or Stainless Steel. Developed for critical service applications in Nuclear power generation and other industries: It is reliable service in vent, drain, gauge column, instrumentation, and other isolation applications. It can be free floating disc and internal wedging mechanism for long term, bubble tight sealing where other valves fail. It meets most severe operating conditions. In many cases, provides same flow capability as a globe twice as large. Double disc gate valve is designed specifically for ease of maintenance in nuclear service and to meet ALARA intent, the 1888 employs the Advance Pressure seal Gasket to reduce the time required to access valve internals, keeping radiation exposure to a minimum. The formed graphite gasket of the AD seal system creates an extremely tight seal between the body and bonnet. The enhanced flexibility and uniformity of the gasket prohibits unacceptable body-to-bonnet leakage caused by minor marring in sealing surfaces. Double disc gate valve will operate reliably and repeatedly when subjected to large pipe nozzle loadings, rapid closure, and repeated cycling. We have considered the effects of extreme temperatures, gross thermal transients, high and low differential pressures, and dual phase fluids in the development of the Double Disc Gate Valve design. Double disc gate valve employs an exclusive disc-and-wedge design which assures tight closing and smooth operation over a long service life by minimizing the accumulation of sediment and sludge present in many refinery and hydrocarbon processing applications. Both discs in these valves are independent and free to move. With the application of internal sealing pressure between them, equally tight shut-off is possible on each of the parallel seats, thus helping to protect against the development of explosive mixtures on either side of the valve in cyclical batching operations.
