Soudarshini Valve · Chennai & Coimbatore
Plug, gate, globe and swing check valves for oil and gas, petrochemical and process industries - designed, cast and tested in-house in Tamil Nadu, under four decades of metallurgical engineering.
Who we are
Soudarshini Valve Private Limited makes flow-control valves for the industries where failure is not an option - oil and gas across upstream, midstream and downstream, petrochemicals, power, fertiliser and pharmaceuticals. Every valve is customised to its service: material, design and pressure rating matched to the medium it will carry.
The company is led by a metallurgist. That single fact shapes everything from material selection to the in-house testing we put every casting through before it leaves the floor.

In-house capability
From design and prototyping to foundry, machining and quality assurance, the Coimbatore plant keeps the full process in-house. That means shorter delivery times, tighter control and a casting that has been checked at every stage rather than assembled from bought-in parts.
Thread whirling, submerged-arc and TIG/MIG/PTA welding, CNC machining, seat-face lapping and horizontal boring - the machinery list reads like the spec sheet of a much larger plant.
Inside the plant →Why engineers specify us
Our raw materials and components come only from suppliers accredited by internationally reputed consultants. Every valve conforms to API, ASME and international standards, and is verified in our own testing lab before dispatch.
Quality & approvals →Industries served
Soudarshini Valve serves the process industries where pressure, temperature and corrosive media leave no room for a weak component.
