DATASHEET FLUXA

Product catalog summary

Overview: This document is a technical datasheet for the FLUXA series of compact streamlined valves, designed for high performance in limited spaces. The valves are suitable for fluid control up to +100°C and are available in various configurations including Normally Closed (NC), Normally Open (NO), and Double Acting (DA).

Specifications:

Temperature Range: -20° to +60°C ambient temperature.
Pilot Pressure: Minimum 4.0 bar to Maximum 8.0 bar.
Valve Body Material: Brass for FLUXA and FLUXA D; Nickel-plated brass for FLUXA DC.
Seal Holder Material: Brass for FLUXA and FLUXA D; Nickel-plated brass for FLUXA DC.
Piston Material: Aluminium.
Cylinder Material: Anodized aluminium.
Piston Rod Material: Stainless steel AISI 304.
Internal O-ring and Shutter Seal: FKM, with options for PTFE or EPDM upon request.

Available Versions: The valves are available in sizes ranging from 1/2" to 2" (PN16) with pipe threads conforming to F/F gas ISO228 standards. They support unidirectional flow (1→2).

Additional Features:

Spacer for cylinder protection from non-compatible fluids is available for D and DC versions.
ATEX certification is available upon request.
Valve status signal is available for NC versions.

Performance Data: The document includes detailed tables showing the maximum differential pressure (ΔP Max) and flow coefficient (Kv) for various valve sizes and configurations. The Kv value represents the volume flow rate of water through the valve under specified conditions (ΔP = 1 bar; T = 5-40°C; density = 1000 kg/m³).

Installation Considerations: For FLUXA D and DC versions, an additional 16 mm should be considered due to the brass spacer between the valve body and cylinder.
