The new double-length bellows valve completes this firms line of single- and double-bellows seal valves (photo). This new double-length bellows allows for the same zero emissions as the single bellows with over double the Cv in the same pipe size. Available in 1/2- to 4-in. sizes in Y, T and angle configurations, these valves are suitable for applications where packed valves may not reliably contain light gases or hazardous system fluids due to leakage in the stem-packing seal area, or stuffing-box-wall packing seal area. — Conval, Inc., Somers, Conn.
