As a leading Metal Seated Valve Manufacturer in Pune, Ultraweld Coat is offering advanced technique valves which are suited to your industrial valve needs. A metal-seated valve is a type of industrial valve designed to handle severe operating conditions where high pressure, high temperature, and abrasive materials are present. Unlike traditional soft-seated valves that use a resilient material like rubber or elastomer for sealing, metal-seated valves utilize metal-to-metal contact for their sealing surfaces. As a top Metal Seated Ball Valves manufacturer in Pune, our design choice offers several distinct advantages, particularly in challenging environments. We are top Metal Seated Valve Suppliers in Pune, where you get perfect solutions for your industrial metal seated valves needs.
Metal-seated valves are highly suited for demanding industrial applications:
Used for isolation purposes. As a leading Metal Seated flanged ball valves manufacturer in Pune, our metal seat provides a reliable seal when the valve is fully closed.
Ball valves with metal seats are used in applications requiring high durability and resistance to high pressures and temperatures.
A Double Block and Bleed (DBB) valve is a type of valve system used primarily in industrial applications to ensure safety and integrity in pipeline systems.
Metal-seated butterfly valves have a disc with metal seating surfaces that offer resistance to high temperatures and pressures while providing efficient flow control.
| Soft seated valve | Metal seated valve | |
|---|---|---|
| Seat material | PTFE or elastomer | Metal, usually hard-coated or hardfaced |
| Temperature | Limited by the seat polymer | Suited to high-temperature service |
| Abrasive or dirty media | Seats are cut and deformed | Hard faces resist scoring and erosion |
| Shut-off | Tight at low cost | Tight when the faces are lapped as a matched pair |
| Operating torque | Lower | Higher |
A soft seat is the economical choice for clean fluids at moderate temperature. Once the fluid carries solids, runs hot, or the valve cycles often under high pressure drop, a metal seat is what survives.
The life of a metal seated valve depends on its sealing faces. Ultraweld Coat applies these surfaces in-house:
Two hard surfaces only seal if they match. After coating, the ball or gate and its seats are ground and then lapped against each other, so each valve leaves with its own matched set. Shut-off tightness is specified as a leakage class; API 598, ISO 5208 and FCI 70-2 are the standards usually quoted. Tell us the class your application needs.
Choose a metal seated valve when the fluid is abrasive or erosive, when the temperature is beyond what a polymer seat tolerates, or when the valve has to keep sealing after many cycles in severe service, such as slurries, steam, or sandy and sour oil and gas streams.
Yes. A metal seated valve can shut off tightly when its hard-coated sealing faces are ground and lapped as a matched pair. Shut-off is specified as a leakage class under standards such as API 598, ISO 5208 or FCI 70-2, and the class is agreed at the enquiry stage.
Often, yes. Worn balls, gates and seats of a metal seated valve are stripped of their old coating, re-coated, and then ground and lapped again as a set. Refurbishment restores the seal at much lower cost than new trim, provided the base metal is undamaged.
