Corrosion, wear, and strict hygiene requirements can make industrial operations challenging. That’s where KDV’s glass-lined diaphragm valves come in. Engineered for durability and reliability, these valves are built to withstand aggressive chemicals, abrasive materials, and harsh environments while delivering exceptional performance.
Why KDV’s Glass-Lined Diaphragm Valves Outperform Other Types of Valve
Not all valves are built to handle the demands of aggressive chemicals, extreme temperatures, or hygienic environments. Here’s why KDV valves, are the preferred choice for industrial applications:
Longer Lifespans: Glass-lined diaphragm valves last significantly longer than traditional valve types in corrosive and abrasive environments, reducing downtime and replacement costs.
Low Maintenance: Designed with high-durability materials, KDV valves minimise the need for frequent repairs or upkeep, making them a cost-efficient solution.
Wide Applications:Our range of valves—including the diaphragm valve weir type—is tailored to meet the unique needs of industries requiring precision flow control, corrosion resistance, and hygienic performance.
How Glass-Lined Valves Are Built:
1.Core Material Selection:
The base structure of the valve is typically made from a durable metal, such as cast steel, carbon steel, or stainless steel. This provides the valve with mechanical strength to handle pressure and stress.
2.Preparation of the Base Surface:
The inner surfaces of the valve body are thoroughly cleaned and treated to ensure adhesion. This involves:
- Sandblasting or grinding to create a rough surface.
- Cleaning to remove any grease, dirt, or residue.
3.Glass Coating Application:
- Glass Composition: The glass lining is made from a specific blend of silica, borates, and other additives tailored to resist chemical corrosion and temperature fluctuations.
- Application Process: The glass is applied in powder or slurry form, coating the internal surfaces of the valve. This can be done manually or using automated equipment to ensure even application.
4.Firing Process:
The coated valve is placed in a high-temperature kiln and fired at temperatures between 800°C and 1,000°C. During this process:
- The glass melts and forms a smooth, uniform layer.
- The glass bonds chemically and mechanically to the metal surface.
5.Quality Inspection and Finishing:
- The valve is inspected for defects like cracks, uneven coatings, or bubbles.
- Any imperfections are repaired through additional firing or re-coating.
- The valve is then assembled with components like seats, seals, and actuators.
Why Opt for Glass-Lined Diaphragm Valves for Your Industrial Applications?
Glass-lined diaphragm valves are a trusted solution for Australian industries operating in demanding environments where performance, reliability, and durability are paramount. Here’s why they’re a superior choice:
- Outstanding Corrosion Resistance: The glass lining forms an inert, seamless barrier that withstands aggressive chemicals, safeguarding equipment and reducing downtime caused by corrosion.
- Hygienic and Sterile Design: With a smooth, non-porous surface, these valves prevent contamination, maintaining sterility and meeting stringent hygiene standards—ideal for sectors such as pharmaceuticals, food production, and water treatment.
- Exceptional Durability: Engineered for resilience, glass-lined diaphragm valves resist wear, abrasion, and extreme temperature fluctuations, ensuring a longer service life with minimal maintenance.
- Optimal Performance: When compared to other valve types, glass-lined diaphragm valves consistently deliver reliability and cleanliness, making them the go-to choice for processes requiring chemical resistance and operational precision.
Industries That Benefit from KDV’s Glass-Lined Diaphragm Valves
Chemical Processing:
- Acid Transfer and Handling: Glass-lined diaphragm valves are a standard choice for transporting highly corrosive acids like hydrochloric, sulfuric, or nitric acid. The glass lining prevents corrosion and extends the valve’s service life in such harsh conditions.
- Solvent Handling: These valves provide an inert and non-reactive surface, making them suitable for managing VOCs and solvents used in chemical synthesis and purification.
- Corrosive Media Control: In reactors, distillation columns, and pipelines, the valves’ resistance to corrosive substances ensures operational safety and reliability.
Pharmaceutical Manufacturing:
- Active Pharmaceutical Ingredient (API) Production: The smooth, sterile surface of glass-lined valves prevents contamination and enables precise flow control during API production.
- Sterile Filtration Systems: These valves are critical in maintaining sterility and ensuring contamination-free operations in filtration and separation processes.
- Cleanroom Distribution Networks: Glass-lined valves facilitate the transport of purified water, steam, and other critical fluids while meeting strict aseptic standards.
Food and Beverage Production:
- Acidic Product Transfer: In processing acidic products like fruit juices, vinegar, and sauces, glass-lined valves protect against corrosion and ensure product purity.
- Cleaning-in-Place (CIP) Systems: The valves can handle aggressive cleaning agents such as caustic or acid washes, maintaining durability and cleanliness.
- Dairy and Syrup Pipelines: Their smooth, non-stick surface ensures hygienic transfer of viscous or sugar-rich liquids without contamination or clogging.
Water Treatment:
- Chlorine Dosing Systems: Glass-lined valves resist chlorine’s corrosive effects, ensuring consistent dosing in water disinfection processes.
- Desalination Processes: They effectively manage brine and other corrosive salts involved in reverse osmosis and filtration stages.
- Wastewater Neutralisation: The valves reliably handle acidic or alkaline chemicals used to adjust pH levels in wastewater treatment systems.
