Product Overview

The BFG7M43HR Pipe Force Check Valve is a high-performance, spring-assisted silent check valve designed for industrial piping systems. It features a unique pipe force design that minimizes pressure drop while preventing backflow, with superior sealing performance and durability for demanding applications.

Key Features

  • Spring-Assisted Closure– Ensures immediate response to prevent water hammer
  • Low Pressure Drop– Optimized flow path design reduces energy consumption
  • Silent Operation– Special disc design eliminates water hammer noise
  • Bubble-Tight Seal– Resilient sealing surface prevents leakage
  • Corrosion Resistance– Stainless steel internal components
  • Compact Design– Requires minimal installation space
  • Maintenance-Free– Rugged construction for long service life

Working Principle

The BFG7M43HR utilizes a spring-assisted disc that opens with forward flow and closes immediately when flow stops or reverses. The spring force ensures positive closure independent of gravity or mounting position. The pipe force design optimizes fluid dynamics to maintain high flow capacity while providing reliable backflow prevention. The resilient seat provides bubble-tight sealing even at low pressures.

Structural Features

  • Integral Spring Chamber– Protects spring from media contamination
  • Guided Disc Movement– Ensures proper alignment and seating
  • Replaceable Seat– Easy maintenance without valve removal
  • Streamlined Body– Minimizes turbulence and pressure loss
  • External Indicator– Visual confirmation of disc position

Applications

  • Industrial water systems
  • HVAC chilled/hot water circuits
  • Fire protection systems
  • Chemical processing plants
  • Power generation facilities
  • Oil and gas pipelines
  • Water treatment plants

Installation & Maintenance

Installation Requirements

  • Install with arrow marking matching flow direction
  • For vertical installation, ensure flow direction is upward
  • Provide adequate straight pipe runs (5D upstream, 2D downstream)
  • Support piping properly to avoid stress on valve body
  • Flush pipeline before commissioning

Maintenance

  • Inspect annually for proper operation
  • Check sealing performance every 2 years
  • Replace seat seal if leakage exceeds allowable limits
  • Lubricate stem (if applicable) during maintenance
