Forged Steel Body, High Pressure Ball Valve for Oil, Gas & Chemical Pipelines

It comes with standard flange ends. That’s why engineers and plant supervisors often select it for high-pressure critical lines — it’s simple to install on site, easy to maintain, and the flange joint holds a reliable seal.

Key Attributes

Forged Steel Body Construction

Our forged flanged ball valve body is produced from solid steel billet through forging, not sand casting. The forging process refines the internal grain structure of the metal, eliminating common casting defects such as porosity, shrinkage cavities and sand inclusions. This gives the valve body far higher tensile strength, impact resistance and pressure shock resistance.

Cast valves work fine for general, low-risk pipelines. But for high-pressure, cyclic load and safety-critical service, forged construction drastically reduces the risk of body crack and catastrophic leakage. Every raw forging can be traced with material heat numbers, and full material test certificates (MTC) are available upon request.

Which industries and media suit this forged flanged ball valve?

This flanged forged ball valve is widely adopted across oil & gas, natural gas transmission, chemical processing, refineries, power generation, offshore auxiliary pipelines, high-pressure water injection systems and fertilizer plants.

It works reliably for clean liquids, compressed air, natural gas, nitrogen, hydrocarbon and a wide range of non-abrasive process fluids. With proper trim and seat material selection, it can also handle mildly corrosive media. It is designed for isolation service, ideal for pipelines that require positive shut-off during routine maintenance or emergency shutdown.

Flanged Connection Design

Flanged connection is the mainstream choice for heavy-duty industrial projects. The standard flange face (RF / RTJ optional) matches ASME B16.5 or GB flange standards. During installation, site crews can easily align bolt holes, place gaskets and tighten bolts without special welding equipment.

The biggest benefit comes during overhaul: you can detach the valve from the pipeline quickly without cutting the pipe. This greatly cuts downtime when you need to inspect internals, replace seats or swap out the whole valve. Compared to threaded ends, flanged joints support much higher pressure ratings; compared to welded ends, it enables repeatable disassembly.

Can this forged ball valve cope with frequent temperature and pressure swings?

Industrial pipelines often see swings in operating pressure and temperature during startup, shutdown and load changes. The forged steel body retains stable mechanical performance under these cyclic conditions.

We match the sealing package to your working envelope. PTFE, RPTFE and metal-to-metal hard seal options are available. Soft seats provide zero-leak bubble tight shut-off for clean service; metal seats suit high temperature or fire-safe requirements. The stem packing design controls fugitive emissions, meeting common environmental requirements for hydrocarbon service.

Material Options for Body & Internal Trim

We maintain a broad material portfolio to match your medium corrosion and temperature requirements:

- Carbon steel: A105 / A105N, ideal for non-corrosive high-pressure gas and oil

- Austenitic stainless steel: F304, F316L, for general corrosive fluid

- Duplex & super duplex: F51, F53, F57, NS2609, NS2607 for seawater, brine and acidic media containing H₂S

We can also customize ball, stem and seat materials. Just share your medium, pH value and working temperature range, and our engineering team will recommend the most cost-effective trim combination.

Size, Pressure Class & Optional Design

Sizes cover DN15 ~ DN300 and larger bore on request. Pressure ratings include PN16, PN40, PN63, PN100, PN160, as well as ASME Class 150, 300, 600, 900, 1500.

Flange faces are available in Raised Face (RF) and Ring Type Joint (RTJ). Fire-safe and anti-static designs can be supplied on request.

You can choose full bore or reduced bore. Full bore cuts flow loss and allows pigging. Reduced bore is smaller and more budget-friendly if pigging is not needed.

Operation Options

We offer several actuation styles to fit your site needs:

- Lever handle: affordable and simple, perfect for manual operation when the valve is easy to get to

- Gear operator: for large bore or high-torque valves, it makes manual opening and closing far easier

- Pneumatic actuator: fast open and close. It pairs with solenoid valves and limit switches for automatic control

- Electric actuator: suited for remote operation, flow regulation, or locations without compressed air supply

We can also add a handwheel override to actuated valves. This lets you operate the valve manually if power or air supply fails.

What inspection standards and documents can you get from us?

Every forged flanged ball valve undergoes mandatory shell hydrostatic test and seat leakage test before packing. We follow API 6D, ASME B16.5 and related industrial standards. Third-party witness inspection is supported if required by your project specification.

We can provide all the paperwork you need: material test certificates, test reports, dimension drawings and operation manuals. Every valve is clearly stamped with its heat number, material grade, size and pressure rating, so you can trace its material and production history without trouble.
