KMA 905 - SED Diaphragm valve

Manually operated valve with stainless steel bonnet and plastic hand wheel

SED Diaphragm Valves

KMA 905 SED diaphragm valve for high purity applications in the pharmaceutical, food, fine chemical and cosmetic industry. It reaches the highest demands of the pharmaceutical industry.

These valves are predestined for applications with high purity, dirty or aggressive fluids and gases. Its smooth surface, without nuts or edges, combined with a self-draining exterior in all assembly positions, gives it an optimised design to be cleaned.
The KMA 905 is standard provided with internal travel stop and stroke indicator.
