1” 150LB F304 Floating Ball Valve（Raised Face Flange, Handle Operated）

I. Product Overview

TIANYU 1” 150LB floating ball valve is a compact, high – performance flow control solution engineered for general industrial and commercial pipelines. Constructed from F304 stainless steel with a raised – face flange connection and manual handle operation, it delivers reliable on – off control for clean media like water, oil, and gas. Designed to meet ASME B16.34 and API 598 standards, it balances corrosion resistance, tight sealing, and ease of use—ideal for light – duty process systems, plumbing networks, and utility applications where simplicity and durability are key.

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.
