The manufacturing process typically includes raw material inspection, precision machining, assembly by skilled technicians, and rigorous testing such as pressure, leakage, and functionality checks to ensure zero defects.

The manufacturing teams work closely with customers at the design phase to customize valves for specific fluid, pressure, temperature conditions, and application requirements. This collaborative approach ensures each valve meets the safety and performance benchmarks required for natural gas handling.

Product Technologies and Types

Floating Ball Valves

Floating ball valves are commonly employed for their simple design and reliable sealing by allowing the ball to float downstream, pressing firmly against the seat. They are ideal for lower-pressure and smaller diameter applications.

Trunnion Mounted Ball Valves

Trunnion-mounted valves have additional support for the ball on the top and bottom trunnions, leading to reduced operating torque and enhanced performance over large diameter and high-pressure pipelines, making them suitable for mainline natural gas transmission.

Top Entry Ball Valves

Top entry designs allow inline maintenance without removing the valve from the pipeline, reducing downtime in critical operations like offshore drilling platforms or LNG processing plants. These valves typically support larger sizes and high-pressure ratings.

Material and Standards

Korean manufacturers use carbon steels, stainless steels (including duplex and super duplex grades), and specialty alloys like Inconel to deliver corrosion resistance, durability, and mechanical integrity especially in sour gas or offshore environments. International standards such as API 6D, ISO 9001, and KS certifications are adhered to ensuring quality and safety.

Applications in Natural Gas Sector

The valves manufactured in Korea are utilized throughout the natural gas supply chain:

- Upstream: Extraction and processing plants require valves robust against pressure fluctuations and abrasive media.

- Midstream: Pipeline transmission valves require durability and tight sealing under high pressure and temperature changes.

- Downstream: Valves for LNG terminals and distribution networks emphasize safety and ease of maintenance.

- Offshore and Marine: Corrosion resistance and reliability for valves used on drilling platforms and offshore rigs.

Service Excellence and OEM Support

Korean suppliers excel in providing full OEM and private-label services including:

- Custom design and engineering according to client specifications

- Comprehensive testing and quality documentation

- After-sales technical support and maintenance consulting

- Packaging and logistics optimized for global shipment
