Fisher Baumann 51000 Low Flow Valve – Stem Sliding Valves

Fisher Baumann 51000 Low Flow Valve is part of the sliding stem valve range that is suitable for demanding low-flow, high-pressure control applications often found in laboratories and pilot plants.

NPS 1/4 or 1/2 valve assemblies of the Baumann 51000 are standard in either cast stainless steel or N10276 nickel alloy

The design of the 51000 low flow valve is ideal for small areas where flexibility is crucial and is often referred to as a miniature valve.
