Acid Proof Flanged Ball Valve for Chemical Dosing Lines
Chemtech Polyplast offers acid proof flanged ball valves engineered for precise and safe handling of aggressive chemicals in dosing and transfer lines. With non-metallic body construction and carefully selected seat and seal materials, these valves are suited for acids, alkalis and corrosive additives used in process plants, water treatment systems and effluent treatment units.
Non-Metallic Construction for Corrosive Media
The valves are designed with corrosion-resistant materials such as polypropylene and compatible elastomers that withstand frequent exposure to strong chemicals. Flanged ends ensure robust pipe connections, while the full-bore design supports smooth, uninterrupted flow of dosing media. The quarter-turn mechanism offers fast opening and closing, limiting operator exposure and ensuring repeatable performance under demanding conditions.

FAQs – Acid Proof Flanged Ball Valve for Chemical Dosing Lines
1. Which chemicals can be handled with your acid proof flanged ball valves?
+
The valves are suitable for many common acids, alkalis and treatment chemicals, subject to proper material selection. Information about the exact chemical, concentration and temperature is required to confirm suitability.
2. Why are non-metallic valves preferred on chemical dosing lines?
+
Non-metallic valves offer excellent resistance to corrosion and do not react with many aggressive chemicals. This helps maintain chemical purity, reduces maintenance and extends the life of valves installed on dosing lines.
3. Can these valves be used with dosing pumps and flow meters?
+
Yes, the flanged ball valves can be installed upstream and downstream of dosing pumps, flow meters and static mixers to provide isolation for maintenance and to support safe start-up and shutdown procedures.
4. Do you provide guidance on chemical compatibility and selection?
+
Chemtech Polyplast can share basic guidance on compatibility and typical material options. Final selection should be made after reviewing process data and, where necessary, consulting detailed compatibility resources or project experts.
5. Are actuator-mounted versions available for automated dosing?
+
Subject to configuration, the valves can be supplied with suitable mounting arrangements for actuators, allowing their use in automated dosing, interlock-based control and remote operation systems.
