Specification
1” 150LB F304 Floating Ball Valve(Raised Face Flange, Handle Operated)
I. Product Overview
II. Key Attribute Specifications
| Category | Details |
|---|---|
| Size | 1” (DN25), matching standard pipeline dimensions for medium – flow applications. |
| Pressure Rating | 150LB (PN20, ~2.0MPa), suitable for low – to medium – pressure systems. |
| Material | – Body/Ball/Stem: F304 stainless steel (18Cr – 8Ni), providing general – purpose corrosion resistance for non – aggressive media. – Seat: PTFE (polytetrafluoroethylene), offering chemical inertness and low – friction sealing. |
| Connection | Raised – face flange (ASME B16.5), ensuring compatibility with standard pipeline gaskets and easy integration. |
| Actuation | Manual handle (90° quarter – turn), enabling quick on – off operation without tools. |
| Temperature Range | – 29℃~180℃ (limited by PTFE seat), covering ambient and moderately hot media. |
III. Feature Description
-
Floating Ball Mechanism: The ball “floats” freely, relying on media pressure to press against the PTFE seat, forming a self – tightening seal. This design compensates for minor pipeline misalignments and pressure fluctuations, ensuring consistent sealing in systems like water supply networks or light oil transfer lines.
-
F304 Stainless Steel Durability: F304’s chromium – nickel alloy resists rust and corrosion in clean, non – acidic media. In potable water systems or compressed air lines, it maintains structural integrity over years of use, outlasting carbon – steel valves in humid or outdoor environments.
-
PTFE Seat Performance: PTFE’s low friction ensures smooth handle operation, while its chemical inertness prevents degradation from water, oils, or mild gases. The seat’s resilience under pressure avoids “cold flow” (permanent deformation), maintaining a tight seal even after thousands of cycles.
-
Raised – Face Flange Compatibility: The flange design aligns with ASME B16.5, allowing seamless connection to standard pipelines using gaskets (e.g., spiral – wound, graphite). This simplifies installation in existing systems, from industrial process lines to commercial plumbing.
Product Overview
IV. Manufacturing Processes
-
Precision Forging/Casting: F304 stainless – steel billets are forged (or cast for larger batches) to shape the valve body and ball. Forging enhances structural density, reducing internal defects like porosity—critical for pressure – rated applications.
-
CNC Machining: The body, ball, and flange faces undergo CNC machining to achieve tight tolerances (±0.05mm). The ball’s sealing surface is ground to Ra ≤0.8μm, ensuring uniform contact with the PTFE seat.
-
Seat Assembly: PTFE seats are compression – molded to fit the valve body, then bonded or press – fitted to prevent displacement. Automated assembly ensures consistent seat compression for reliable sealing.
-
Testing: Each valve passes:
- Hydrostatic Test: 1.5×150LB (3.0MPa) for 30 minutes to verify body integrity.
- Seat Leak Test: 1.1×150LB (2.2MPa) with air/water to confirm zero leakage.

V. Product Advantages
-
Cost – Effective Reliability: F304 stainless steel and PTFE deliver long service life in non – corrosive media, reducing replacement costs. In a 5 – year commercial plumbing study, TIANYU valves required 60% fewer repairs than brass alternatives.
-
Easy Integration: Flange connections and standard dimensions simplify retrofitting into existing pipelines. For contractors, this cuts installation time by 20–30% versus specialty valves.
-
Low Maintenance: The floating ball and PTFE seat require minimal upkeep. In light industrial applications (e.g., compressed air systems), annual maintenance (lubrication, visual checks) suffices for continued operation.
-
Versatile Media Compatibility: Handles water, mineral oils, natural gas, and air—suited for HVAC systems, small – scale process lines, and utility networks.
Application
VI. Product Applications
-
Commercial Plumbing: Controls hot/cold water flow in hotels, office buildings, and restaurants. The 1” size fits standard fixture lines, ensuring reliable shut – off for sinks, boilers, or cooling towers.
-
Light Industrial Processes: Regulates non – corrosive fluids (e.g., lubricating oil in machinery, compressed air in workshops). The 150LB rating suits low – pressure hydraulic or pneumatic systems.
-
Utility Networks: Manages water/gas distribution in municipal or campus pipelines. F304’s corrosion resistance withstands outdoor exposure, ensuring long – term service in utility grids.
-
Food & Beverage: Meets sanitary standards for clean media (e.g., water in bottling plants). PTFE’s non – toxic, non – sticking properties prevent contamination.
- Seal Upgrades: Viton® for higher temps (200℃+), metal seats for abrasive media.
- Actuation: Add electric/pneumatic actuators for automation.
- Material: 316 stainless steel for chloride – rich environments (e.g., coastal plumbing).
Tailored to your pipeline’s media, temperature, and control needs.
