Mart Flow Control Valves

IntroductionPTFE-lined diaphragm valves are widely used in industries requiring corrosion resistance, high purity, and reliable shutoff. These valves are designed to handle aggressive chemicals, slurries, and highly pure fluids, making them a preferred choice in industries such as chemical processing, pharmaceuticals, water treatment, and food production.
1. Use of PTFE-Lined Diaphragm ValvesPTFE-lined diaphragm valves are used to control, regulate, and shut off the flow of various fluids, including:
Highly corrosive chemicals (acids, alkalis, solvents)Slurries and viscous mediaHigh-purity fluids in pharmaceutical and food applicationsWastewater and effluent treatment
These valves provide excellent resistance to chemical attack, making them superior to standard metal or rubber-lined valves in aggressive fluid applications.
2. Applications of PTFE-Lined Diaphragm Valves
2.1 Chemical Processing
Handling of acids, alkalis, and solvents
Used in chlor-alkali production, sulfuric acid handling, and organic synthesis
Preferred for processes involving toxic or hazardous chemicals
2.2 Pharmaceuticals and Biotechnology
Sterile and hygienic fluid handling
Used in clean-in-place (CIP) and sterilize-in-place (SIP) systems
Ideal for handling high-purity water, buffer solutions, and drug formulations
2.3 Water and Wastewater Treatment
Chemical dosing and pH control systems
Used in desalination plants, industrial wastewater treatment, and potable water purification
2.4 Food and Beverage Industry
Handling food-grade chemicals and sanitizers
Used in syrup and beverage processing
Ensures compliance with FDA and food safety regulations
2.5 Semiconductor and Electronics
Handling ultra-pure water and specialty chemicals
Used in semiconductor fabrication plants to maintain contamination-free environments

3. Range of PTFE-Lined Diaphragm Valves
These valves come in various configurations to suit different applications. The key parameters include:
