Hygienic Welded U-Shaped 3 way Diaphragm Valve

Hygienic Welded U-Shaped Diaphragm Valve
This "zero-dead-leg" valve is the gold standard for pharmaceutical high-purity water (WFI) and sampling loops. Its unique U-shaped body is welded directly into the process line, allowing the fluid to flow through the main pipe while the diaphragm controls a branch.

Design: Minimal stagnant zones (dead legs) to prevent biofilm.
Hermetic Seal: Diaphragm isolates moving parts from the product.
Joints: Permanent orbital welding ensures zero leak paths

Technical Attributes: Hygienic Welded U-Shaped 3-Way Diaphragm Valve

 

1,Body Configuration,"3-Way / T-Pattern for diverting, mixing, or bypass functions."

2,Zero-Dead-Leg,"Designed to eliminate ""dead legs"" in distribution loops (typically < 2:1 ratio)."

3,Body Material,Forged 316L Stainless Steel (1.4435) with controlled sulfur content.

4,Connection Type,Extended weld ends for automated orbital welding into sterile lines.

5,Diaphragm Seal,High-durability PTFE with EPDM backing or pure medical-grade EPDM.

6,Product Isolation,The diaphragm ensures zero contact between the stem/actuator and the media.

7,Surface Finish,Internals typically Electropolished to Ra ≤ 0.25 μm - 0.5 μm.

8,Flow Direction,Multi-directional; can be used for diverting (1-in/2-out) or mixing (2-in/1-out).

9,Actuation Options,Manual handwheel or Pneumatic (Air-to-Open/Air-to-Close).

10,Sterilization,Fully resistant to frequent SIP (Steam-In-Place) cycles at 121°C–134°C.

11,Drainability,Specifically engineered to be self-draining when installed at a defined angle.

12,Standard Compliance,"Built to ASME BPE, FDA, and USP Class VI requirements."

13,Traceability,Body is laser-etched with heat numbers for EN 10204 3.1 material certification.

14,Operating Pressure,Capable of handling up to 10 bar (145 psi) in both flow directions.

15,Modular Bonnet,Allows for easy replacement of diaphragms without removing the body from the line.
