Product Description
The Dwyer MVB-LF1 is a compact 1/8" mini brass ball valve designed for manual shutoff where installation space is limited. Its female x female NPT process connections provide a practical connection arrangement for compact panels, instrumentation assemblies and skid-mounted systems.
The valve uses a lever handle for straightforward manual operation and incorporates pure PTFE ball seats for bubble-tight shutdown. A double seal mechanism allows the valve to be installed in either flow direction, providing flexibility when routing process lines.
The body and ball are constructed from chrome-plated brass for a compact and durable valve assembly. A fluoroelastomer O-ring stem seal provides sealing around the valve stem.
Rated from -29" Hg vacuum to 450 psi CWP (31 bar), the MVB-LF1 is suitable for compressed air, instrumentation and general utility shutoff duties where a compact manual valve is required.
