SPX Flow APV DELTA SD4 double seal valve

SPX Flow’s APV DELTA SD4 double seal valves are designed for safe media separation applications. Their hygienic characteristics and long seal life make them suitable for use in the food, beverage, pharmaceutical and chemical industries. The valves are designed for shut-off, changeover or tank bottom valve applications with other configurations available on request.

Safe media separation is provided by the valve’s design that contains two seat seals. The hygienic characteristics of the valves are primarily due to their ball-shaped housing, crevice-free sealing and leakage discharge valves which enable drainage as well as cleaning of the neutral cavity.

To maximise operating life and maintain process integrity, the valves need to be routinely maintained. The company has released a video providing a step-by-step guide for the upkeep and maintenance of the valves.

The video provides users with an in-depth walk-through of standard maintenance procedures, including a step-by-step guide on how to disassemble and assemble the valves; replace the seat seal; and preserve the seal from leakage.
