Part No. MVB-WF4 |
The Dwyer MVB-WF4 is a compact 1/2" mini brass ball valve designed for tight locations where a standard-size valve may be difficult to install. It features female x female NPT process connections and a wedge handle for straightforward manual operation.
The valve uses a chrome-plated brass body and ball for compact and durable construction. A fluoroelastomer O-ring provides the stem seal, while pure PTFE ball seats provide bubble-tight shutdown and broad media compatibility.
A double seal mechanism enables bidirectional operation, allowing the valve to be installed in either direction within the line. This provides greater installation flexibility for panels, skids, instrumentation systems, and utility piping.
Rated for 450 psi CWP, with an operating pressure range from -29" Hg vacuum to 450 psi (31 bar), the MVB-WF4 is suitable for compressed air, instrumentation, and general utility shutoff applications.
