Pressure-reducing valve FP-42T

diaphragmhydraulically-operatedpilot

Overview
The BERMAD 42T (product code FP-42T) is an elastomeric, line-pressure-driven pilot-operated pressure reducing valve designed for fire protection systems and related industrial applications. It reduces high upstream pressure to a precise, preset and stable downstream pressure while maintaining low head loss, suitable for pump discharge control and prevention of over-pressure on sprinklers, hose stations and hydrants.

Features & Benefits

• Safety and reliability
  • Low headloss design — increased safety with reduced supply pressure
  • Proven, simple pilot operation with fail-safe actuation
  • Single-piece elastomer seat (VRSD technology)
  • Obstacle-free, uninterrupted straight-through flow path
  • No mechanical moving parts in the main flow path
• Performance
  • Fast, smooth stabilization in response to pressure fluctuations
  • Very high flow efficiency due to straight-through flow
  • Rated working pressure PN25 / 365 psi
• Fire protection design
  • Face-to-face length standardized to ISO 5752 EN 558-1
  • Accurate and stabilizing pressure control for sprinkler and hydrant systems
• Maintenance
  • In-line serviceable for minimal system disruption
  • Fast and easy cover removal

Typical Applications

• Sprinkler feed systems
• Fire pump discharge control
• Hose station supply
• Fire hydrant supply
• Foam firefighting systems
• Zonal pressure control
