3 Inch Brass Ball Valve Price – Heavy Duty & Certified
Get competitive 3 inch brass ball valve price for industrial pipelines. Durable forged brass, full port, PTFE seats, 600 WOG, fire-safe design. Ideal for water, oil, gas. Certified quality, factory direct.
Description
The 3‑inch brass ball valve functions as a core control component within piping systems for rapid shut‑off and medium flow‑direction switching. Built with a forged brass body and fitted with PTFE seats, it delivers bubble‑tight shut‑off performance across the‑20 °C to 120 °C operating temperature range. Its full‑port configuration minimizes flow resistance and mitigates system pressure loss, making it well‑suited for pipelines transporting high‑flow liquids, gases and mildly corrosive media.
Material & Process Advantages
- Body / Bonnet: CW617N European‑standard forged brass, dezincification‑resistant and capable of resisting stress‑corrosion cracking.
- Ball: Chrome‑plated brass or stainless‑steel sphere with polished surface for reduced operating torque during actuation.
- Seat: 25 % glass‑filled PTFE, balancing wear resistance and low‑friction properties.
- Stem: Dual O‑ring leak‑proof construction with anti‑ejection locking groove.
Every unit undergoes hydrostatic cycle testing for 5000 open‑close operations as well as 2.4 MPa shell strength testing. Manufactured quality complies with EN 13828 and ASTM B124 specifications.

Typical Applications
- Municipal water supply and secondary distribution networks: deployed as sectional isolating valves to facilitate maintenance workflows.
- HVAC systems: chilled‑water and hot‑water diversion with stable pressure‑withstanding and temperature‑resistant performance.
- Petrochemical auxiliary piping: low‑pressure oil circuits and cooling‑water loops, with optional fire‑safety rating available.
- Gas pressure regulating stations: shut‑off duties for natural gas branch lines, meeting Class‑A leakage‑rate requirements for gas valves.
- Marine and offshore engineering: salt‑spray corrosion resistance; compact layout conserves installation footprint.

FAQ
Q1: Can the 3‑inch brass ball valve be deployed for high‑pressure steam circuits?
A: Standard PTFE seats are rated for saturated low‑pressure steam up to 120 °C. For higher‑temperature conditions reaching 180 °C, upgraded reinforced PEEK seats or all‑stainless‑steel bodies are recommended. Please forward your operating‑condition parameters to our sales team for application validation.
Q2: What is the actual bore dimension of this full‑port valve? Does it feature a reduced bore?
A: Our 3‑inch full‑port ball valve maintains a 76 mm bore matching the inner diameter of mating same‑size piping with no flow‑path reduction. Some low‑cost competing products downsize internal bores to 2.5‑inch equivalent; always cross‑reference official engineering drawings. A measured flow coefficient Cv=380 is provided to guarantee uncompromised system design flow capacity.
