Brand: RETZ/ We have been committed to continuous innovation in the field of fluid control since 2005...

American standard imported diaphragm valves are specifically designed for highly corrosive media such as acids, alkalis, and chemical solvents when using PTFE diaphragms, and for controlling weak acids, weak alkalis, inorganic salts, viscous fluids, lime slurry, fibrous, and powdery substances when using rubber diaphragms.

The flexible diaphragm of the American standard imported diaphragm valve isolates the fluid and is bolted to the valve stem, moving up and down during operation. The valve opens when the diaphragm rises and closes when the diaphragm descends. The valve body and cover are separated by the intermediate diaphragm, ensuring that components above the diaphragm, such as the valve cover and valve stem, are not eroded by the medium. Additionally, there is no external leakage or contamination of the fluid by external air.

RETZ diaphragms undergo various tests under harsh conditions to confirm their durability and safety. Our external seals and seat seals are highly reliable, with stable quality and performance that are highly praised by users across a wide range of industrial fields.

If you have any requirements, such as "I want this type of diaphragm valve!" or "I want to use it for this fluid!", please feel free to tell RETZ (American RETZ Diaphragm Valve) editors.

Strictly adhering to the essence of American standards, setting a global benchmark for quality.

Globally, American standard diaphragm valves are synonymous with quality assurance due to their exceptional performance. These valves strictly follow the specifications of international authoritative organizations such as ANSI (American National Standards Institute) and ASME (American Society of Mechanical Engineers), reflecting a rigorous attitude and pursuit of excellence from material selection to craftsmanship. Whether it's the material, dimensions, or pressure rating of the valve body, all have passed strict international certifications. Unified standards ensure the valve's universality and interchangeability worldwide, enabling seamless integration for both cross-border projects and upgrades of existing American standard pipeline systems, solving problems for users.

Sealing like silk, leaving no room for leakage.

In terms of sealing performance, American standard diaphragm valves are unparalleled. They use high-precision ground valve seats and high-performance elastic diaphragms, assembled with automated precision to minimize the gap between the diaphragm and the valve seat, creating an impenetrable sealing barrier. Some models even incorporate innovative American dual-diaphragm stacking sealing technology, achieving zero leakage even under extreme conditions such as high pressure and high corrosion, safeguarding industries like chemicals and energy, and effectively preventing environmental pollution and economic losses caused by media leakage.

Exceptional materials, tackling complex working conditions.

In material selection, American standard diaphragm valves use high-quality alloy materials that comply with ASTM standards, such as CF8M stainless steel and WCB carbon steel, combining high strength and corrosion resistance. The diaphragms are available in various American standard certified materials like EPDM, PFA, and PTFE, capable of handling different media such as acids, alkalis, high temperatures, and organic solvents. Whether it's highly corrosive chemicals in the petrochemical industry or sanitary fluids in the food industry, the material advantages ensure long-term stable operation and extended service life of the valves.

Main performance

The flexible diaphragm of the American standard imported diaphragm valve isolates the fluid and is bolted to the valve stem. It moves up and down during operation, opening the valve when the diaphragm rises and closing when the diaphragm descends.

The valve body and cover are separated by an intermediate diaphragm, ensuring that the valve cover, valve stem, and other parts above the diaphragm are not corroded by the medium. And there is no external leakage or external air entering the contaminated fluid.
