Does the VFR+L compressed air preparation unit, NEW DEAL series, maintain set pressure with variable supply and low flow rates?

Yes. The VFR+L compressed air preparation unit, NEW DEAL series maintains the set pressure reliably even with variable supply pressure and at low flow rates. Its piston-type pressure reducing valve and robust design ensure pressure stability in harsh conditions. The unit includes shut-off valve, air filter and lubricator, and the V3V valve enables quick aeration and venting. Specifications supporting this performance: supply pressure up to 18 bar (discharge RA up to 10 bar), output pressure ranges 0â8 and 0â12 bar, filtration options 4/20/50 Âµm, condensate discharge modes (manual, semi-automatic RMSA, automatic SAC/RA), and nominal flows from 480 l/min (1/4") to 1900 l/min (3/8"â1/2" at 6 bar input, Îp=1 bar). Operating temperature up to +50Â°C and BSP connections complete the package.

Can the VFR+L compressed air preparation unit, NEW DEAL series, operate reliably in harsh environments with automatic condensate discharge options?

Yes. The VFR+L compressed air preparation unit, NEW DEAL series, is built for harsh environments: piston-type pressure reducing valve ensures high reliability and stable set pressure despite variable supply and low flow rates. It includes shut-off valve, air filter (4/20/50 Âµm), pressure reducer, lubricator and V3V valve for quick aeration/venting. Operates up to +50Â°C, supply pressure up to 18 bar (RA discharge up to 10 bar), output ranges 0â8/0â12 bar, and offers manual, semi-automatic (RMSA) or fully automatic condensate discharge (SAC, RA). Multiple BSP connection sizes and nominal flows (480â1900 l/min) make it suitable and reliable for demanding conditions.

How does the piston-type pressure reducing valve in the VFR+L compressed air preparation unit, NEW DEAL series, ensure stable output at low flow?

The piston-type pressure reducing valve in the VFR+L compressed air preparation unit, NEW DEAL series, ensures stable output at low flow by using a robust piston mechanism that maintains set pressure despite variations in supply pressure and low volumetric demand. Key points: - Piston regulation: The piston provides a larger effective sealing area and greater mechanical stability than a diaphragm, producing finer control and reducing sensitivity to small flow changes common at low flow rates. - Balanced response to supply variations: The design compensates for fluctuations in inlet pressure (up to 18 bar) so the discharge pressure (adjustable 0â8 or 0â12 bar) remains steady even when flow is minimal. - Reduced pulsation and stick-slip: The pistonâs mass and guided movement dampen rapid pressure swings and prevent stickâslip behavior that can cause instability at low flows. - Integrated components support stability: The upstream filter (4/20/50 Âµm) and shut-off valve ensure clean, controlled supply; the V3V venting function permits quick aeration/venting without disturbing set pressure; condensate management (manual, RMSA, SAC, RA) prevents liquid carryover that could affect valve performance. - Suitable sizing: Nominal flow ratings (e.g., 480 l/min for 1/4", 1900 l/min for 3/8" and 1/2" at 6 bar input, Îp=1 bar) and proper connection sizes (BSP 1/4"â1") ensure the valve operates within its stable control range even at low demand. Together, these features allow the VFR+L unitâs piston-type pressure reducing valve to hold a stable, accurate output pressure during low-flow operation and under varying supply conditions.
