Hygienic Non-return welding valve

Technical Attributes: Hygienic Non-Return Welding Valve

1,Body Material,AISI 316L (1.4404) stainless steel for maximum purity.

2,Connection Type,"Butt-weld ends for permanent, leak-proof orbital welding."

3,Internal Surface,High-mirror polish Ra ≤ 0.8 μm (standard) or Ra ≤ 0.4 μm.

4,Seal Compounds,"FDA-approved EPDM, FKM (Viton), or PTFE."

5,Opening Pressure,"Low cracking pressure, typically 0.05 bar to 0.1 bar."

6,Max. Pressure,Standard operational rating up to 10 bar (145 psi).

7,Temp. Range,Resilient from −10°C to +140°C (dependent on seal material).

8,Cleaning Profile,Full CIP (Clean-In-Place) and SIP (Steam-In-Place) compatibility.

9,Mechanism,Spring-loaded plunger ensures rapid closure to prevent backflow.

10,Spring Design,Open-coil spring to prevent product entrapment and buildup.

11,Certification,Meets 3-A Sanitary Standards and EHEDG guidelines.

12,Flow Direction,Unidirectional; usually marked with a laser-etched arrow on the body.

13,Drainability,Designed for 360° drainability when installed in vertical lines.

14,Maintenance,Clamp-body design (on some models) allows quick internal access.

15,Seal Protection,Mechanical metal-stop prevents over-compression of the gasket.
