Butterfly valves have been around for a long time, and are used for a variety of applications. They made their first appearance during the 1930s, and have been utilized by several industries ever since. Often made out of cast iron, butterfly valve's name is based from the functionality of its disc.
The wafer butterfly valve is one of the most common types of valves in industrial pipelines. The structure of wafer butterfly valve itself is relatively small. It is only necessary to put the butterfly valve in the middle of the flange at both ends of the pipe, and use the stud bolt to pass through the pipe flange and the pair.
The manual valve is a valve operated by the handle and the hand wheel, and is a commonly used valve on the equipment pipeline.
Valves are the most common equipment in chemical companies. It seems easy to install valves, but if they are not implemented in accordance with the re...

In modern industrial processes, reliable filtration is critical for both product quality and operational efficiency. Traditional filtration systems often struggle to meet the precision, flexibility, and automation needs of high-demand industries.
RKSfluid Candle Filter Systems provide versatile solutions that address these challenges, delivering precise, automated, and energy-efficient filtration across multiple sectors, including chemicals, pharmaceuticals, food & beverage, and new energy.
1. Chemical Industry – Maximizing Catalyst Recovery
During PTA (Purified Terephthalic Acid) production, traditional filter presses often fail to recover catalysts smaller than 5 μm, resulting in material loss and increased costs.
RKSfluid’s solution uses a dual-stage filtration approach:
This configuration achieves a 99.2% catalyst recovery rate, saving companies over USD 400,000 per year in raw materials.
By combining high-precision filtration with automatic backflushing and modular candle arrangements, chemical plants can maintain continuous operations while reducing downtime for maintenance.
2. Pharmaceutical Industry – Ensuring Sterile Filtration
Pharmaceutical manufacturing requires sterility and process traceability, particularly for antibiotic fermentation liquids.
RKSfluid candle filters incorporate:
This ensures compliance with FDA and cGMP standards, allowing the filters to operate safely in sterile production lines while minimizing contamination risks.
3. Food & Beverage Industry – Clarity, Safety, and Nutrition
In juice clarification and beverage processing, filters must remove particles without compromising nutritional content.
RKSfluid candle filters use 0.2 μm PTFE membranes that efficiently eliminate:
At the same time, essential nutrients such as Vitamin C are preserved.
Field tests from a leading juice manufacturer demonstrated:
Our candle filter systems are designed for high-precision, automated, and energy-efficient performance — helping clients enhance product quality, extend equipment lifespan, and reduce operating costs.
As an ISO 9001 certified manufacturer, RKSfluid operates a 20,000 m² intelligent production base with in-house filter element fabrication and CNAS-accredited testing capabilities.
Backed by a 24/7 global support network across 50+ countries, we deliver reliable solid-liquid separation solutions that keep your production running clean, safe, and efficient.
