Thin Stainless Steel Flange Ball Valves

Core Product Advantages

● Space-saving slim design: One-piece forged slim body, 30%-50% thinner and 20%-40% lighter than conventional flanged ball valves, ideal for confined spaces and lightweight equipment.

● High flow efficiency: Full bore ball with smooth flow path, pressure drop ≤ 0.01 MPa at rated flow, significantly higher flow capacity than globe valves.

● Reliable sealing: PTFE soft seal (ANSI Class VI, zero leakage) or metal hard seal for high-temperature and high-pressure service; bidirectional sealing compatible with dual-direction flow lines.

● Easy operation & low maintenance: 90° rotation for quick on-off, low operating torque; simple structure for easy replacement of core components; minimal fouling risk.

● High-quality materials & compliance: 304/316/316L stainless steel with excellent corrosion resistance; food & pharmaceutical grade meets FDA/3A; complies with GB, ANSI, DIN standards.

All parameters have undergone rigorous testing to ensure product stability and reliability, directly matching the buyer's actual usage needs.

Typical Application Scenarios

● Thin Stainless Steel Flange Ball Valves, with their slim design, efficient switching, and reliable sealing, are widely used in piping systems across various industries where installation space and switching efficiency are critical. Specific suitable scenarios are as follows:

● Food & Pharmaceutical: 316L + PTFE soft seal, FDA/3A compliant; slim design for dense production lines.

● Petrochemical: 316/316L hard seal, Class 150-600, for high-temp solvents and sour crude.

● Municipal & Construction: 304 soft seal for water supply, HVAC, and secondary water supply systems.

● Industrial & Marine: Slim and lightweight for hydraulic, pneumatic, and marine systems; strong vibration resistance.

● New Energy & Power: Hard seal for high-temp cooling and steam lines in PV, wind power, and power stations.

Product Definition & Working Principle

Thin Stainless Steel Flange Ball Valves are rotary fluid control valve with a slim forged body and flanged connection, used for fast on-off and basic flow regulation.

Working Principle:Actuator drives the stem and ball to rotate 0°-90°.

● 0°: Port aligned with flow → fully open.

● 90°: Port perpendicular to flow → fully closed.

● Intermediate angles provide basic flow throttling.

Compliant with GB, ANSI, DIN standards; 304/316/316L material for wide media compatibility.

Main Types & Application Matching

Material Selection Guide

Body / Ball / Stem

● 304: General water, air, oil; -20°C~100°C; cost-effective for municipal and general industry.

● 316: Chloride, seawater, weak acid; better pitting resistance.

● 316L: Strong corrosion, hygienic service; FDA/3A for food & pharma.

Seals

● PTFE: -20°C~180°C, strong corrosion, zero leakage.

● FKM (Viton): -20°C~200°C, excellent chemical resistance.

● Stainless steel hard seal: -40°C~425°C, high pressure, abrasive media.

● Stellite hard seal: Up to 500°C, extreme wear resistance.

Installation & Maintenance

Installation

1.Bidirectional seal; follow flow arrow for maintenance convenience; reserve sufficient operation space.

2.Clean flanges; use proper gaskets; tighten bolts crosswise in 2-3 stages.

3.Clean pipeline; check ball rotation; test electric actuator before installation.

4.Slow pressurization, vent air, pressure test for 30 minutes before commissioning.

Maintenance

1.Regular inspection: check leakage, bolt tightness, and operation; lubricate stem monthly.

2.Replace gaskets, seats, or packing if leakage occurs; refinish or replace worn hard seal surfaces.

3.Clean exterior, apply anti-rust oil; enhance protection in chloride/salt environments.

4.Do not repair under pressure; clear jams gently; troubleshoot actuators safely.

5.Establish maintenance records for lifecycle management.
