Zoloto 1040 Pressure Reducing Valve - Front View

Overview

The Zoloto 1040A and 1040B are compact, self-operated pressure reducing valves (PRVs) designed for water service applications in industrial and commercial facilities. These valves automatically reduce high upstream pressure to a stable, lower downstream pressure without requiring any external power source.

The 1040A variant features a bronze body (IS 318 Gr. LTB 2), while the 1040B is constructed from forged brass (IS 6912 Gr. FLB), offering enhanced durability. Both models use hot brass forged trim components, ensuring reliable performance under demanding conditions. The screwed female ends conform to IS 554/BS 21/ISO 7 standards for easy integration into existing piping systems.

These PRVs are engineered for sensitive fluid regulation where consistent outlet pressure is critical. A 1/4" BSP tapping is provided for pressure gauge installation, allowing operators to monitor downstream pressure continuously.

Key Features

  • Self-operated design — no external energy source required
  • Compact construction for easy installation in confined spaces
  • Hot brass forged trim components for extended service life
  • Screwed female ends to IS 554/BS 21/ISO 7
  • 1/4" BSP pressure gauge connection for outlet pressure monitoring
  • Food-grade nitrile rubber O-rings for safe water handling
  • Virtually noiseless operation
  • Low maintenance requirements
