Description
I. Basic Function of 4 Inch Flanged Ball Valve
The 4″ ball valve – a DN100 unit within the DN50–DN300 medium‑bore product family – features a 2 piece body design that enables rapid on/off switching with just a 90° turn. Its internal full port ball valve construction provides a large‑bore passage, effectively minimising fluid resistance. Commonly installed in waterworks, oil/gas, and chemical main pipelines, it serves to isolate media during equipment outages, preventing pressure loss and material leakage. It is a standard isolation valve for large‑scale industrial lines.
II. Material and Connection Options
The valve body is available in two primary material grades: WCB carbon steel and 304/316 stainless steel. For standard water and natural gas lines, the carbon steel ball valve offers better cost efficiency; for corrosive conditions involving acids, alkalis, or seawater, the stainless steel 4″ ball valve is recommended. Seals are PTFE as standard, with metal hard‑facing available for high‑temperature duties. The standard end connection is ANSI flanged, with butt‑weld ends optionally available upon request.

IV. Application Scenarios
This 4 inch flanged ball valve is extensively employed in natural gas transmission mains, chemical process units, power‑plant circulating water systems, large HVAC installations, and marine main pipelines. Manufactured to international fluid engineering standards, every unit is hydrostatically and pneumatically tested prior to shipment and carries full API and CE export certifications. Factory‑direct supply eliminates intermediary margins, ensuring stable and transparent 4″ ball valve price levels.
V. Frequently Asked Questions for Overseas Buyers
Q1: What factors directly influence the 4″ ball valve price?
A1: Body material, pressure rating, actuator type, and order volume all affect the final quote. Stainless steel and high‑pressure versions command a premium, while large project orders are eligible for tiered wholesale discounts.
Q2: Can the 4″ ball valve be customised with an extended stem?
A2: Yes – we support customisation including extended stems and fire‑safe designs. Customised variants may slightly adjust the 4″ ball valve price, but all modified products undergo the same comprehensive factory testing protocols as standard units.
