Water treatment plants are the backbone of urban and industrial water management. Whether for municipal supply, industrial process water, or wastewater treatment, selecting the right industrial valve is crucial in ensuring reliable and efficient flow control. With numerous valve types available, the selection process can be overwhelming. That’s where Aira Euro Automation, one of the leading valve manufacturers in India, steps in with precision-engineered solutions tailored for the water treatment sector.
This blog will help you understand the types of industrial valves used in water treatment plants and how to choose the most suitable one for your specific application.
Why Valve Selection Matters in Water Treatment Plants
In a water treatment facility, valves regulate flow, control pressure, isolate equipment, and direct processes between treatment stages such as sedimentation, filtration, and disinfection. A poorly selected valve can lead to leakage, downtime, energy loss, and even system failure.
Choosing the right water treatment valve ensures
Here’s what you must evaluate before selecting an industrial valve for a water treatment application
Fluid Type
- Clean Water: Requires valves with low-torque actuation and corrosion resistance
- Sludge/Slurry: Demands robust valves with full-bore designs to prevent clogging
- Chemicals (Chlorine, Alum): Needs PTFE-lining or special sealing materials
Pressure and Temperature Range
Operating pressure and temperature should be within the valve’s rated limits. For high-pressure zones, Aira’s pressure-tested valves ensure leak-proof operation.
Valve Operation
- Manual Valves: For simple, low-critical flow control
- Electric/Pneumatic Actuators: For remote control, automation, and integration with PLC systems.
Valve Material and Seal
- Body Materials: Cast Iron, SS, PVC, WCB
- Seal Options: EPDM (for potable water), PTFE (chemical resistance), Nitrile, Viton
Maintenance and Installation
Choose compact valves for tight spaces
Go for modular valves that are easy to disassemble and service
Each valve has a specific role based on the treatment phase
Butterfly Valves
Use: Flow regulation in large pipelines
Pros:
- Lightweight and economical
- Ideal for large diameter lines with moderate pressure
Aira offers Rubber/EPDM/PTFE-lined options with manual or pneumatic actuators.
Gate Valves
Use: On/off service, especially for intake and isolation
Pros:
- Minimal pressure loss
- Bi-directional sealing
Aira manufacturers rising and non-rising stem configurations for space flexibility.
Globe Valves
Use: Precise flow regulation and throttling
Pros:
- Excellent control over flow rate
- Effective for chemical dosing
Aira Advantages durable SS trims with customizable seats for chemical compatibility.
Ball Valves
Use: Quick shut-off and chemical handling
Pros:
- Tight shut-off
- Compact and easy to automate
Aira Advantage provides full-bore, fire-safe, and anti-static designs with multi-port options.
Check Valves (Non-return Valves)
Use: Prevent reverse flow, protect pumps
Pros:
- Simple design
- No manual operation required
Aira Advantage Swing-type, dual-plate, and spring-loaded models to fit diverse system needs
Plug and Diaphragm Valves
Use: Sludge handling and slurry flow
Pros:
- Designed to handle thick fluids
- Minimal clogging
Aira offers custom seats for high-viscosity and abrasive media
