Valves for Water Treatment Plants
Complete Valve Solutions for WTP, ETP & STP — Municipal Water Supply, Effluent Treatment & Sewage Treatment
Industrial Valve Supplier for Water Treatment Projects in India
Water treatment infrastructure — whether a municipal water treatment plant (WTP), effluent treatment plant (ETP), or sewage treatment plant (STP) — relies entirely on the reliability of its valve systems. From raw water intake to treated water distribution, each process stage demands the right valve type, material, and actuation method to ensure uninterrupted operation.
Aarya Sales is a specialist water treatment valve supplier in India, offering the complete range of valves required across all stages of water and wastewater treatment. With ISO 9001:2015 certified products and a track record across municipal, industrial, and government water projects, we deliver quality valves at competitive prices with fast dispatch nationwide.

Why Aarya Sales for Water Treatment Plant Valves
Selecting the correct valve for a water treatment plant goes beyond just size and pressure rating. Material compatibility with chlorine, alum, ferric chloride, ozone, and other treatment chemicals is critical. Rubber-lined butterfly valves and PTFE-lined diaphragm valves are standard for chemical service, while fusion-bonded epoxy (FBE) coated ductile iron gate and butterfly valves are the standard for potable water compliance.
Aarya Sales supplies valves conforming to IS 780, IS 2906, IS 14846, BS 5163, AWWA C504, AWWA C509, and AWWA C515 standards — ensuring compliance with CPHEEO guidelines and state PWD/PHED project specifications. Our valves are suitable for supply to Jal Jeevan Mission projects, AMRUT scheme water supply works, and industrial ETP/STP installations.
We regularly supply to municipal corporations, water boards, EPC contractors, JNNURM projects, and large industrial plants including textiles, pharmaceuticals, food processing, and chemical manufacturing that operate their own effluent treatment facilities.
Key Material Specifications for Water Valves
Body materials available: Cast Iron IS 210, Ductile Iron IS 1865 (GGG40/GGG50), Carbon Steel, Stainless Steel SS 304 / SS 316, Bronze, and PVC/UPVC for smaller sizes. Seat and disc materials include EPDM, NBR, PTFE, and Neoprene depending on service fluid and temperature. Epoxy-lined CI/DI valves are standard for potable water compliance.

Frequently Asked Questions — Valves for Water Treatment Plants
Water treatment plants (WTP, ETP, STP) commonly use Butterfly Valves for large-bore flow isolation and control, Gate Valves for on/off isolation of water mains, Check Valves to prevent backflow at pump discharge, Diaphragm Valves for chemical dosing and corrosive media, Knife Edge Gate Valves for sludge and slurry service, and Ball Valves for smaller instrumentation and sampling lines.
For raw water and treated water lines, Cast Iron (CI) and Ductile Iron (DI) with epoxy coating are standard. For chemical dosing and corrosive service, Rubber-Lined valves, SS 316, or PVC-lined valves are preferred. For seawater or brackish water, Duplex Stainless Steel (DSS/2205) or Bronze valves are suitable. Diaphragm valves use rubber or PTFE linings depending on chemical compatibility.
Aarya Sales supplies water treatment valves from 15 NB (½") to 2700 NB (108"). Large-bore butterfly valves for intake structures and clearwell outlets are available up to 2700 NB, while gate valves for distribution mains are available up to 600 NB and above on special order.
Yes. For sewage treatment plants, we supply Knife Edge Gate Valves for raw sewage and sludge lines, Rubber-Lined Butterfly Valves for aeration tank outlets, Diaphragm Valves for chemical feed systems, and Non-Return Valves (Check Valves) for pump discharge. All are available in corrosion-resistant materials suitable for aggressive sewage environments.
Yes, we supply Electric Actuated and Pneumatic Actuated Butterfly Valves and Gate Valves used in SCADA-controlled water treatment facilities. These support remote open/close operation and are available with limit switches, position indicators, and 4-20mA positioners.
Valves for potable water must be compatible with drinking water standards. We supply valves compliant with IS 780, IS 2906, BS 5163, and AWWA C504/C509/C515. Internal coatings use NSF/ANSI 61-certified fusion bonded epoxy (FBE) or rubber lining to ensure no contamination of treated water.
