Sanitary Diaphragm Valves
Sanitary Diaphragm Valves
Yuanzhou sanitary diaphragm valve diaphragms are available in FDA-compliant EPDM and PTFE-backed materials, providing reliable isolation between the process medium and the valve actuator. Their flexible, low-retention design supports tight shut-off, repeated opening and closing, and efficient CIP/SIP cleaning, making them suitable for food, beverage, dairy, pharmaceutical, biotechnology, and other high-purity processing systems.

EPDM + PTFE Dual-Layer Diaphragm for Reliable Hygienic Sealing
Yuanzhou sanitary diaphragm valves feature a dual-layer EPDM and PTFE diaphragm design, combining the chemical resistance and low-adhesion surface of PTFE with the flexibility and mechanical support of EPDM. This structure improves sealing stability and cycle life while reducing the risk of diaphragm fatigue, deformation, media penetration, and contamination commonly associated with single-material diaphragms, making it suitable for CIP/SIP systems and high-purity food, beverage, pharmaceutical, and biotechnology applications.

U-Type Diaphragm Valve with Smoother Flow and Lower Pressure Loss
Compared with conventional weir-type diaphragm valves, Yuanzhou sanitary U-type diaphragm valves feature a wider, smoother flow channel with less internal obstruction, helping reduce turbulence, pressure loss, and product accumulation. This design is better suited for high-flow, viscous, or particle-containing media that require gentler transfer and improved drainability, while maintaining reliable isolation between the process medium and the actuator.
