EPDM+PTFE Double layer diaphragm
The EPDM and PTFE diaphragm is engineered for durability and efficiency. When the valve is closed, the diaphragm’s design ensures a secure seal with the valve body, minimizing stress and extending its lifespan. Built to endure high temperatures and demanding working conditions, it offers reliable performance in challenging environments.
Specifications:
- Size range: DN25-DN100
- Double-layer diaphragm temperature tolerance: -20°C to 150°C
EPDM Single layer diaphragm
The single-layer diaphragm is reinforced with a vulcanized fiber layer, enhancing its mechanical strength and durability. Engineered for high sealing stability under rising pressure and temperature, it ensures reliable performance in demanding conditions. The diaphragm’s reinforcing fiber is hardened on stainless steel bolts, improving rubber-to-metal adhesion and overall cohesion. This design makes it particularly suitable for operations in vacuum environments.
Specifications:
– Size range: DN6-DN100
– Rubber diaphragm temperature tolerance: -10°C to 100°C
FAQ
What are sanitary diaphragm valves?
Sanitary diaphragm valves are specialized flow control devices designed for high hygiene and precision. They use a flexible diaphragm to regulate or block the flow of fluids, ensuring contamination-free operation in sensitive applications.
What materials are they made from?
These valves are typically constructed from high-grade stainless steel, such as SS316L, for durability and corrosion resistance. The diaphragm is often made from EPDM+PTFE or rubber, offering chemical resistance and suitability for a wide range of applications.
What industries use these valves?
Sanitary diaphragm valves are widely used in industries that demand strict hygiene, including pharmaceutical manufacturing, food and beverage processing, and sanitary applications like cosmetics and biotechnology.
How do they ensure hygiene and safety?
The design eliminates dead spaces and allows for easy cleaning (CIP or SIP), reducing the risk of contamination. The diaphragm acts as a barrier between the process fluid and the operating mechanism, ensuring high levels of safety and hygiene.
What sizes and configurations are available?
Sanitary diaphragm valves are available in sizes ranging from 1/2″ to 4″ (DN6-DN100), with configurations like straight-through and 3-way options to suit varied system designs and flow requirements.
