The complexity of both auto slide valves is essentially the same.  We (ExxonMobil) have completed testing of the Z&J valve at our Torrance Refinery, and are completely satisfied with its operation after almost 2 years of operation.  We have proved out its throttling capabilities and are very happy with its dual-seat design and low steam consumption, which should be very robust over the long haul.  We have also been operating Delta Valves for almost 6 months.  I recommend that you competitively bid  both valves and do a thorough evaluation relative to your installation and process needs.  If you want to talk more, call me at 703-846-5905.   Best regards – Mitch Moloney
