Overview
The W.E. Anderson BBV-1F is a flanged 3-valve block manifold engineered for precision instrument isolation and pressure measurement in demanding industrial environments. Constructed from 316 stainless steel bar stock, the BBV-1F delivers exceptional strength, corrosion resistance, and durability across repeated pressure cycles. This manifold is ideal for process instrumentation, transmitter isolation, and system maintenance where reliable, low-torque operation is critical.
Key Features
- Three-valve configuration: two isolate valves + one equalize valve for complete system control
- 316 stainless steel body, stems, and valve assemblies for superior corrosion resistance
- Hard-seated stems with PTFE packing for minimal operating torque and long service life
- Rated to 6000 PSI (400 bar) and 464°F (240°C)
- 1/2″ NPT female connections (both main inlet and instrument ports)
- Direct-mountable design for compact installation
