Top Applications of Flanged Ball Valves in Oil, Gas, and Chemical Industries

In the labyrinth of pipelines, processing plants, and pressurized systems, one component silently governs the flow: ball valves. When it comes to demanding industrial environments, particularly in oil, gas, and chemical sectors, not just any valve will do. You need strength. You need precision. And most importantly, you need trust.

And when the name “Unison Valves” appears on one, it brings with it a promise forged in the heart of India’s industrial hub, delivering to standards that rival the world’s best.

What Are Flanged Ball Valves?

At their core, ball valves are quarter-turn shutoff devices that use a rotating ball to control flow. They offer low-pressure drop, high flow capacity, and tight sealing. But when it comes to high-pressure, high-volume systems, flanged ends make all the difference.

Flanged Ball Valves are connected using bolted flanges, creating a secure, leak-proof joint. This design allows them to excel in environments where mechanical stress and media aggressiveness would overwhelm conventional solutions.

In the broader family of valve technology, there are multiple types of ball valves based on their installation technique, viz. Flanged End, Screwed End, Socket Welded End, Tri-clamp or Tri-clover end, Orbital Welded etc.,  . Each serves a distinct role in industrial piping systems. Unison Valves manufactures and customizes these variations for specific flow control needs, marking its place as a leading ball valve manufacturer in India.

How They Differ from Threaded or Welded Ball Valves

Flanged variants offer easier maintenance, faster access for inspection, and safer disassembly, especially in hazardous environments. While welded joints are permanent and threaded joints can be situationally challenging to remove once complete piping installation is done.  Flanged end ball valves bring robustness and longevity without compromising on accessibility, making them more serviceable.

Design and Pressure Ratings for Industrial Use

Unison Valves designs flanged ball valves that meet ASME B16.5; BS-10 Table D, Table E, Table F; ND10/16; BS EN ISO 1092 PN10, PN16; DIN, etc., that comply with Indian, American, British, International, German, and many more standards. Additionally, the valves also comply with design standards such as API 6D, ASME B16.34, ISO 17292, BS standards, and many more. Their offerings cover pressure classes up to Class 800  and temperature ratings suited for both cryogenic and high-temperature fluids. These valves are available in materials like WCB, CF8M, and Duplex Steel, providing performance tailored to specific process media and pressure conditions.

Why Flanged Ball Valves Are Ideal for Industrial Systems

Why are flanged ball valves preferred in oil and gas? The answer lies in their unmatched versatility and safety assurance in dynamic, high-risk environments.

Leak-Proof Connection in High-Pressure Environments

When transporting flammable gases or corrosive fluids at high pressures, sealing integrity is non-negotiable. Flanged connections use robust gaskets and multiple bolting points to ensure leak-proof closure, even under pulsating pressure loads. Unison’s valves are hydro-tested and fire-tested to meet the highest safety benchmarks.

Easy Maintenance and Replacement

With bolts instead of welds, flanged ball valves can be easily removed, inspected, or replaced without cutting into the pipeline. In critical installations, this saves downtime, reduces labour costs, and increases overall plant efficiency, especially crucial for offshore oil platforms and chemical batch reactors.

High Chemical and Temperature Resistance

The chemical and gas industries deal with extreme media, from highly acidic solutions to superheated steam. Unison’s flanged ball valves offer high resistance to corrosion, scaling, and thermal expansion, ensuring reliable shutoff even under aggressive chemical attack or thermal shock.

Key Applications in the Oil Industry

The oil sector is a triad of upstream, midstream, and downstream activities, each with its own fluid control challenges. Oil and gas ball valve uses span from exploration to refining, and Unison caters to each with specialized solutions.

Upstream Exploration and Production

In drilling operations, valves must handle mud, sand-laden crude, and even gases under pressure. Flanged ball valves here ensure rapid isolation and safety during well servicing, blowout prevention, and reservoir tapping.

Midstream – Pipelines and Storage

This segment involves the transportation of crude oil and refined products over long distances. Flanged ball valves serve as control nodes in pipelines and storage systems, enabling flow diversion, pigging, and emergency shutoff. As a valve manufacturer in Maharashtra, Unison supplies valves that meet stringent compliance norms for transport-grade safety.

Downstream – Refineries

At the refining stage, chemical complexities increase. Valves must tolerate high temperatures and chemically reactive compounds. Unison’s flanged ball valves are ideal for this environment, offering precise flow control and durability over prolonged cycles.

Key Applications in the Gas Industry

As the world shifts toward cleaner energy, natural gas becomes a critical transitional fuel. Reliable flow control is essential across the value chain, and ball valve manufacturers in India are stepping up to meet the demand, led by companies like Unison.

LNG and Natural Gas Pipelines

From cryogenic LNG storage tanks to intercity gas pipelines, flanged ball valves ensure tight shutoff and operational safety. Unison's flanged ball valves for gas pipelines are designed to handle low-temperature media without brittle failure.

Gas Metering Skids and Distribution Lines

In city gas distribution (CGD) networks, compact yet reliable valves are key. Unison’s flanged valves integrate seamlessly into skids, enabling accurate flow measurement, calibration, and leakage control.

Safety Isolation Systems

In both upstream and downstream segments, fail-safe shutoff valves are vital. Unison’s API-compliant flanged ball valves act as first responders during pressure surges or system malfunctions, ensuring protection of life, assets, and the environment.

Key Applications in the Chemical Industry

Few sectors challenge engineering durability like chemicals. Acids, oxidizers, solvents this is where ordinary valves surrender. But flanged ball valves for chemical industries, especially from Unison, are built for endurance.

Acids, Solvents, and Corrosive Fluid Handling

Whether it's hydrochloric acid, caustic soda, or acetone, Unison’s materials like CF8M and Hastelloy withstand them all. These valves are internally coated where needed and externally protected against environmental degradation.

Process Control in High-Temperature Environments

Many chemical reactions involve heat. Ball valves in such zones must retain sealing integrity without thermal expansion distorting performance. Unison’s valves are engineered for dimensional stability.

Explosion-Proof Valve Installations

In volatile environments, ignition risks are real. Unison offers antistatic ball valves with fire-safe designs and explosion-proof accessories, keeping hazardous processes under safe control.
