Inquire NowDescription
The Pneumatic Tank Bottom Diaphragm Valve is engineered for efficiently discharging medium from tanks without resorting to the chamber. This versatile valve is available in a range of sizes from 1″ to 4″ (DN25-DN100) and is designed to withstand varying temperatures and pressures, making it ideal for diverse industrial applications. Crafted with precision, the valve features a forged body made from high-quality stainless steel (1.4404 / 316L / 1.4435 NB2) or a cast body (1.4404 / 316L) for enhanced durability and reliability.
With the ability to handle high temperatures—up to 150°C with a stainless steel actuator and 130°C with a plastic actuator—this valve is suitable for demanding environments. It offers a range of pressure capabilities, including options for normally closed and normally open configurations. The diaphragm material options, including EPDM + PTFE (double layer), ensure compatibility with various media. Certified for safety and performance, this valve meets multiple industry standards, ensuring peace of mind in its operation.
