Metal seated ball valves are a crucial component in industrial applications that demand durability, precision, and resistance to extreme conditions. As an ISO/API certified metal seated ball valve manufacturer, we are committed to delivering reliable, high-performance valve solutions that meet the toughest process challenges across sectors like oil and gas, petrochemicals, power plants, mining, and refineries.

What Are Metal Seated Ball Valves?
Metal seated ball valves differ from standard soft-seated valves by using metal-to-metal contact between the ball and the seat. These valves are designed to perform in high-temperature, high-pressure, abrasive, and corrosive environments—conditions where soft seats like PTFE or Teflon would fail.

Our metal seated ball valves are manufactured with advanced hard-facing materials such as:

Tungsten Carbide

Stellite

Chromium Carbide

Nickel-based Alloys

This ensures exceptional hardness, wear resistance, and prolonged service life even in slurry or steam service.

ISO & API Certifications – Why They Matter
Being ISO 9001:2015 and API 6D/607 certified reflects our adherence to international quality and safety standards.

ISO 9001:2015
This certification confirms that our quality management system consistently meets customer and regulatory requirements. It ensures standardized procedures in design, production, and customer service.

API 6D
Specifically for pipeline valves, API 6D outlines stringent requirements for design, material traceability, inspection, and performance testing of ball valves. It’s a key certification for valves used in the oil and gas industry.

API 607
Covers fire-safe testing, ensuring our valves maintain seal integrity during and after a fire—critical for hazardous operations.

By complying with these certifications, we guarantee that every valve we manufacture is safe, reliable, and globally accepted.

Our Manufacturing Capabilities
As a specialized metal seated ball valve manufacturer, we combine state-of-the-art CNC machining, automated welding, and strict quality control processes in our in-house facility.

Key Highlights:

Each valve undergoes hydrostatic, pneumatic, and high-temperature seat leakage testing to meet international standards.

Industries We Serve
Our metal seated ball valves are trusted by global clients in:

Oil and Gas
Handling crude oil, sour gas, and high-pressure fluids demands superior sealing and erosion resistance.

Refineries and Petrochemicals
High-temperature catalytic cracking and process streams with suspended solids require rugged valve materials.

Power Plants
Steam lines and blowdown systems need metal seats that won’t degrade under thermal cycling.

Mining and Slurry
Heavy slurry containing sand, gravel, or corrosive chemicals can rapidly destroy soft-seated valves.

Pulp and Paper
Abrasive chemicals and fibrous media call for durable flow control solutions.

Design Features of Our Metal Seated Ball Valves
Our valves are engineered with robust features tailored for critical service:

Live-loaded stem packing – Ensures zero fugitive emissions

Double block and bleed design – Enhances safety and isolation

Self-relieving seat design – Manages pressure buildup in closed cavity

Fire-safe construction – Compliant with API 607

Anti-static device – Prevents sparking during actuation

Optional integrated hard coatings increase life cycles by resisting galling, erosion, and corrosion.
