2 Inch SS Ball Valve Price | ANSI Class 150/300 Full Port Industrial
Explore 2 inch ss ball valve price for ANSI 150/300 industrial pipeline. API 598 certified 316 stainless steel full port design ensures reliable shut-off, low pressure drop, and long service life.
Description
In large and medium-sized industrial pipelines serving petroleum, chemical, water treatment and HVAC sectors, the 2 inch ss ball valve ranks among the most widely used mainline shut-off components. Boasting a moderate nominal bore, it balances high flow capacity with compact installation requirements, enabling rapid and tight medium shutoff via a 90-degree rotational movement. For global engineering purchasers, evaluating 2 inch ss ball valve price extends far beyond unit purchase cost; it essentially assesses whether this DN50 (2-inch) standard valve can deliver consistent sealing performance throughout its service life alongside minimal maintenance expenditure.
Material & Specifications: Compliant with Mainstream Industrial Standards
Our 2-inch stainless steel ball valves are engineered in strict accordance with ASME/ANSI standards. The valve body is forged from A351 CF8M or 316 stainless steel, delivering outstanding resistance to intergranular corrosion and pitting corrosion, making it well-suited for weak acid, alkaline liquid and salt-containing medium conveyance. A 304 stainless steel variant is also available for conventional working conditions.
Referring to 2 inch ball valve 316 stainless steel specifications, the 316-grade variant boasts an extended service lifespan in chloride-rich environments and high-temperature scenarios, rendering it an optimal pick for chemical processing and marine engineering projects. An anti-blowout stem structure is integrated to prevent stem ejection caused by internal pipeline pressure under high-pressure operating conditions, eliminating potential safety hazards entirely.
Core Technical Parameters & Selection Guidelines
This 2-inch stainless steel ball valve comes in full-port and standard-port flow channel configurations. The full-port design is highly recommended, as its inner bore matches the pipe inner diameter to cut pipeline pressure drop to the minimum and maximize fluid transportation efficiency.

Certifications & Testing: Guaranteed Reliability for Every Unit
Quality acts as the decisive factor in valve procurement. While offering competitive 2 inch ss ball valve price, we place heavy emphasis on product compliance and standardized testing protocols:
- API 598 inspection: Every finished valve undergoes shell hydrostatic testing at 1.5 times the rated pressure and sealing testing at 1.1 times the rated pressure before delivery, with leakage rates far below threshold values specified by industrial standards.
- Traceable material records: Material Test Reports (MTR) are supplied for each batch of raw materials to verify authentic material grades.
- Fire-resistant construction: The full product line passes API 607 fire testing. In case of fire emergencies, the metal secondary seal stops medium leakage effectively to mitigate operational risks.
- Anti-static setup: Anti-static springs are installed between the ball and stem to guarantee safe operation within flammable and explosive working environments.
Application Scenarios
- Chemical & Petrochemical Industries: Shut-off control for branch pipelines and main pipelines transporting weak acids, solvents and corrosive chemical fluids.
- Oil & Gas Sector: Serves as dependable isolation valves for oil product and natural gas pipelines.
- Water Treatment & Environmental Protection: Installed on main inlet and outlet pipelines of sewage treatment plants and reverse osmosis systems.
- HVAC & District Energy Systems: Controls the on-off state of cooling water, chilled water and hot water pipelines. The full-port structure drastically reduces energy consumption of circulating pumps.
Frequently Asked Questions for Overseas Buyers
Q1: How can consistent product quality be secured during bulk procurement of 2-inch stainless steel ball valves?
A: Our manufacturing system complies with the ISO 9001 quality management system. Critical dimensional inspection is carried out via Coordinate Measuring Machines (CMM), and each valve completes API 598 pressure testing before shipment. Material traceable certificates (MTR) and inspection reports are delivered together with goods to guarantee uniform performance across batches and full compliance with international engineering acceptance criteria.
Q2: Do the quoted 2 inch ss ball valve price include fire-proof and anti-static configurations?
A: Our standard products are pre-equipped with anti-blowout stems, anti-static assemblies and fire-safe structures certified to API 607 standards by default. These essential safety accessories are incorporated into the quotation without extra upgrade fees, enabling transparent procurement and cost-effective investment.
Q3: Is this valve compatible with steam or high-temperature medium working conditions?
A: The standard PTFE seat adapts to media temperatures below 180°C. For saturated steam or high-temperature thermal oil (≤250°C), we suggest selecting high-temperature variants fitted with PEEK seats or metal hard-sealing structures. Kindly specify actual operating temperature and pressure parameters when placing orders, and we will customize targeted high-temperature sealing solutions accordingly.
We maintain competitive 2 inch ss ball valve price without compromising industrial durability and fully traceable certification systems, delivering economical and trustworthy pipeline isolation solutions for your engineering projects.
