Diaphragm Valve for Chemical Industries in India
T-FLOW supplies high-performance diaphragm valves for chemical industries in India, engineered for aggressive media, corrosive slurries, and high-purity streams. With hygienic isolation, precise throttling, and reliable shut-off, our valves protect downstream equipment and ensure process safety across acid, alkali, solvent, and brine handling lines.
What is a Diaphragm Valve in Chemical Processing?
A diaphragm valve uses a flexible elastomer or PTFE diaphragm to separate the process media from the bonnet and actuation mechanism. This sealed flow path prevents contamination and fugitive emissions—critical for chemical plants where leak-tight integrity, corrosion resistance, and clean operation directly affect product quality and EHS compliance.
Common Types for Chemical Service
- Weir-type diaphragm valves for accurate throttling and CIP/SIP compatibility.
- Straight-through (full-bore) valves for viscous fluids and slurries with minimal pressure drop.
- Pneumatic diaphragm valves with positioners for automated flow control loops.
- Manually operated diaphragm valves for on/off isolation in utility and dosing lines.
- PTFE/EPDM-lined diaphragm valves for acids, caustics, and solvents in corrosive duty.
Key Features & Specifications
- Leak-tight bonnet isolation with flexible diaphragm (EPDM, PTFE, NBR, FKM).
- Body materials: CI/SG iron, CF8/CF8M stainless steels, and alloy options.
- End connections: flanged, tri-clamp, or threaded as per line standards.
- Working pressure/temperature ranges tailored for chemical compatibility.
- Manual handwheel or pneumatic actuator with optional limit switches/positioners.
Applications in Chemical Industries
- Acid/alkali transfer lines in chlor-alkali, dyes & pigments, and specialty chemicals.
- Dosing and metering skids for reagents, catalysts, and neutralization systems.
- Solvent handling with sealed isolation to minimize emissions and vapor loss.
- Water treatment, DM/RO plants, and effluent neutralization at chemical sites.
- Pharma-chemical and fine chemicals requiring hygienic, cleanable flow paths.
Why Choose T-FLOW for Chemical Duty Valves
- Enhanced safety via diaphragm isolation—no packed gland leakage to atmosphere.
- Excellent corrosion resistance with PTFE/EPDM linings and SS bodies.
- Accurate throttling for pH control, dosing, and flow regulation loops.
- Lower maintenance—few wetted moving parts and easy diaphragm replacement.
- Custom builds for Indian standards, site conditions, and OEM skids.
