Product Description

Stainless Steel Food Grade Triclamp Pneumatic Weir Type epdm Diaphragm Valve

The Stainless Steel Diaphragm Valve is designed for precise fluid control in hygienic processing systems. It utilizes a flexible diaphragm pressed against a weir to regulate flow, while the pneumatic actuation and plastic handle allow for both automated and manual operation. The three-way configuration enables efficient diversion or mixing of media, minimizing dead zones to ensure hygienic performance. This makes it ideal for aseptic and high-purity applications in food, beverage, and pharmaceutical industries.

Working Principle
The valve regulates flow by lifting or lowering the diaphragm against the weir, directing liquid between multiple pathways. The pneumatic actuator provides automatic switching, while the ergonomic plastic handle ensures manual control when required. Its sanitary weld-on design reduces leakage risks and ensures long-term durability in demanding sterile environments.

Technical Specifications

• Material: Sanitary-grade stainless steel with PTFE diaphragm

• Size Range: 1/2" to 4" (customizable)

• Pressure Rating: Up to 145 PSI (varies by model)

• Temperature Range: -20°C to 180°C (-4°F to 356°F)

• Connection Type: Weld-on sanitary ends

• Surface Finish: Polished Ra ≤ 0.8 μm for hygienic performance

• Compliance: FDA, 3A, ISO 9001 standards

Quality & Service

• 3 years quality guarantee

• Certified materials: ISO 9001, FDA, SGS

• Fast delivery: 7-10 days for urgent orders

• 20 years of global exporting experience for reliable and tailored solutions
