PTFE Diaphragms In chemical processing, air-operated pumps, diaphragm valves, and corrosive media handling, diaphragms act as critical seals between media or pressure zones. Unlike seals elements, diaphragms have no drag leakage at contacting surfaces and demand lower tolerances and surface finishes, greatly enhancing system reliability. PTFE Diaphragms – Engineered for Extreme Media and Precision Applications 在化工、气动泵、隔膜阀及高腐蚀介质输送领域，隔膜作为两种介质或压力区间的密封 屏障，承担着关键作用。 与传统密封件不同，隔膜无接触面拖曳泄漏，对公差和表面质量要求更低，极大提升设 备可靠性。 Flexibility and long service life are the primary demands placed on diaphragm materials and...

Typical Applications- PTFE Diaphragms for AODD Pumps Application of PTFE Diaphragms in AODD Pumps In air-operated double diaphragm (AODD) pumps, the diaphragm serves as a flexible barrier separating the pneumatic drive from the liquid being pumped. It moves back and forth to draw in and discharge fluid during operation. PTFE is widely used for diaphragms in chemically aggressive, high-temperature, or contaminationsensitive environments due to its outstanding chemical resistance, thermal stability up to 260°C (500°F), and non-contaminating nature. Compared to conventional elastomeric materials...

Typical Applications- PTFE Diaphragms for Diaphragm Valves Application of PTFE Diaphragms in Diaphragm Valves In diaphragm valves, the diaphragm serves as a critical sealing element that isolates the process media from the valve actuator, ensuring zero leakage and preventing contamination. PTFE diaphragms offer exceptional chemical inertness and thermal resistance, making them ideal for demanding applications involving aggressive fluids or strict purity requirements. Compared to elastomer-based diaphragms, PTFE provides superior aging resistance and long-term stability under harsh conditions....

Typical Applications- PTFE Diaphragms for Diaphragm Valves CONSTRUCTION – OPEN & CLOSED MOLDED DESIGNS Diaphragm structure varies based on valve function—whether normally open or normally closed. Dytron offers full manufacturing capabilities for both open-molded and closed-molded diaphragm designs to meet diverse application needs. DIAPHRAGM FITTINGS Dytron also provides various diaphragm fittings to meet specific installation requirements. Common types include: 结构形式 – 开模与闭模设计 • Threaded Pin – A standard screw-in fitting for secure attachment to the actuator. • Bayonet Fitting – Allows for a...
