Premium EPDM Diaphragm for +GF+ 317 Series D75 Diaphragm Valves
Engineered for industrial automation systems, this EPDM diaphragm is specifically designed for +GF+ 317 Series D75 valves, ensuring seamless compatibility and optimal performance. Crafted from ethylene propylene diene monomer (EPDM), the diaphragm offers robust chemical resistance and durability in challenging environments, including repetitive steam-in-place (SIP) cycles. Its elastomeric properties provide reliable sealing under high pressure, while the double-layer construction with PTFE reinforcement enhances resistance to abrasion and deformation. Compatible with temperatures ranging from -51°C to 135°C (-60°F to 275°F), it meets rigorous standards like ASME BPE and USP Class VI, making it ideal for sanitary applications in pharmaceuticals, food processing, and water treatment.
Superior Performance and Longevity
The EPDM diaphragm for the 317 Series D75 features a precision-molded design that guarantees bubble-tight sealing and bidirectional flow control. Its laser-etched traceability codes ensure compliance with regulatory requirements, while the parylene surface treatment option (available on select models) reduces friction and extends service life. With a pressure rating of up to 150 PSI and a cycle life exceeding 10,000 operations, this diaphragm withstands demanding industrial conditions. Easy to replace via the valve’s union design, it minimizes downtime and maintenance costs. Backed by +GF+’s ISO 9001 and ISO 14001 certifications, it delivers consistent performance in corrosive media, including chlorinated water and mild acids.
Versatile Applications and User-Friendly Design
Designed for DN25 to DN150 piping systems, this EPDM diaphragm is suitable for diverse industrial settings, from chemical processing to aquaculture. Its compatibility with +GF+’s 317 Series flanged, socket, or threaded valve configurations ensures flexibility in installation. The diaphragm’s FDA-compliant materials (CFR 21 177.2600) make it safe for potable water and food-grade applications, while optional vented designs accommodate aggressive chemicals like sodium hypochlorite. With NSF 61 certification and a compact, lightweight structure, it balances safety, efficiency, and cost-effectiveness, positioning it as a reliable choice for maintaining fluid control in critical automation processes.
