PBM Designs Patented Flush Tank Valve— Literature Available

PBM, Inc., Irwin, Pa., has designed a patented flush tank valve virtually eliminating the pocket area normally found between tank bottoms and other valves that directly mount to tanks and vessels.

PBM also has a patented Adjust-OSeal design that allows in-line adjustment of the valve seats.

According to PBM, this design is great for vacuum service. It provides a seal on the upper seat in addition to the bottom seat. The design does not rely on downward pressure to create the seal. The PBM flush tank valve is designed to meet AMSE code for pressure vessels. The FT valve can also be fitted with body taps, allowing it to be steam purged "on-line," making it ideal for aseptic applications.

PBM can custom machine mounting flanges to adapt the valve to other manufacturers weld pads and still keep pocket area to a minimum These valves are available in fractional sizes to 8 inches, SST, carbon steel, alloy 20, Hastelloy and other metals. All valves are precision machined and polished to exact surface finishes. Easily actuated. Bolt-on style pads are also available.
