Description

316 Stainless Steel Low-Pressure Sustaining Valve – Z-Tide Industrial Series RFLT

Precision direct-acting pressure sustaining (back pressure) valve for low-pressure applications, engineered to maintain stable upstream pressure.

Key Features

  • Function: Pressure sustaining / back pressure valve (BPV)
  • Operation: Direct acting
  • Port Sizes: 1/2, 3/4, 1, 11/2 or 2 BSPT; optional NPT or BSPP (G) thread
  • Back Pressure Adjustment: 0.2 – 1.5 Bar, displayed on included pressure gauge
  • Max Inlet Pressure: 5 Bar
  • Test Pressure: 16 Bar
  • Temperature Range: -15°C to +100°C (dependent on seal material)

Materials & Construction

  • Body: 316 stainless steel; optional Duplex 316 stainless steel
  • Internals: Stainless steel
  • Seals: NBR standard (+60°C), optional Viton (+100°C) or EPDM
  • Media Compatibility: Air, water, pure water, light oils, and fluids under 40 CST compatible with materials of construction

Performance & Design

  • Maintains a pre-set back pressure upstream; valve closes when pressure drops below the setpoint and opens when pressure rises
  • Pressure gauge indicates the sustained upstream/back pressure for monitoring
  • Designed for sensitive, stable, and repeatable pressure control in critical low-pressure systems

Applications

  • Laboratory and process control systems
  • Water and RO systems requiring back pressure maintenance
  • Low-pressure compressed air or fluid lines with critical upstream pressure requirements
