Ball Valves

Ball valves are critical isolation components in high-pressure and process-critical piping systems across oil and gas, marine, petrochemical, and gas distribution industries. Our ball valves are engineered and manufactured in accordance with API 6D standards, ensuring dependable shut-off performance in demanding liquid and gas service applications. Designed for high integrity service conditions, these valves are suitable for pressure classes up to ASME Class 1500 and are tested to meet stringent international compliance requirements. Each valve is built with a focus on safety, durability, and long-term operational reliability in mission-critical installations.

Product Description

Our ball valves feature a robust 3-piece side-entry trunnion mounted construction that ensures structural stability under high differential pressures. The trunnion-supported ball design reduces operating torque while maintaining consistent seat alignment and sealing performance.

Manufactured as per API 6D and pressure-temperature rated in accordance with ASME B16.34, the valves are available in sizes ranging from 2 inch to 12 inch with flanged RF end connections as per ASME B16.5. Standard material construction includes ASTM A105N body and high-strength alloy steel trim components, with Devlon V-API or equivalent seat materials selected for enhanced sealing integrity.

End Connections

Flanged RF as per ASME B16.5 (other end connections on request)

Body Material

ASTM A105N (Carbon Steel) and other materials as per project requirement

Trim Materials (Ball / Stem / Seat)

ASTM A105N / ASTM A322 Gr. 4140 / Devlon V-API Seats

Pressure Temperature Rating

As per ASME B16.34 and Up to Class 1500 with maximum allowable working pressure

Leakage Class & Testing

Tested as per API 6D Clause 10 and Fire Safe design as per API 607

Non Destructive Testing

MT 100% and additional RT / UT as per project specification

Certification Standards

API 6D Monogram Certified, ISO 9001:2015 and QSL Level 2

Service Application

Oil and Gas, Marine, Petrochemical, and Gas Distribution services

Operation & Accessories

Lever operated and Gear operated options and Vent valve provision

Technical Advantages

High-pressure and high-temperature environments require valves that maintain integrity under mechanical stress and thermal variation. Our API 6D monogram-certified manufacturing ensures consistent quality control, material traceability, and compliance with international oil and gas standards.

The trunnion mounted configuration enhances sealing reliability under fluctuating pressure conditions, reducing the risk of seat deformation and leakage. Fire-safe construction as per API 607 ensures that sealing performance is maintained even in the event of external fire exposure, providing an additional layer of operational safety.

Industry Applications

Oil & Gas

Used in upstream, midstream, and downstream facilities for high-pressure pipeline isolation, process units, and hydrocarbon service applications in compliance with API 6D requirements.

Petrochemical & Refinery

Installed in critical process lines handling hydrocarbons, solvents, and high-temperature media where fire-safe and pressure-rated performance is mandatory.

Gas Transmission & Distribution

Applied in gas pipeline networks and compressor stations requiring tight shut-off and high-pressure reliability.

Marine & Offshore

Used in fuel systems, ballast lines, and offshore platforms where corrosion resistance and fire-safe performance are essential.

Power Generation

Installed in steam, condensate, and auxiliary systems requiring high-pressure isolation and operational reliability.

Water & Infrastructure

Applied in treatment and distribution systems requiring durable shut-off and corrosion-resistant construction.

Reduced Maintenance Through Robust Design

Frequent maintenance and unexpected shutdowns can significantly impact operational efficiency in industrial systems. The trunnion mounted architecture reduces seat wear and stabilizes ball positioning, contributing to extended service life in high-pressure and high-cycle applications.

The side-entry bolted body design allows easier inspection and maintenance access compared to welded constructions, minimizing downtime during servicing. Fire-safe secondary metal-to-metal sealing provides continued functionality even under extreme thermal conditions.
