Product details

I. Product Definition and Structural Features

1. Definition

An angle valve with flange is a valve that integrates an angle valve design with flange connections, used for 90-degree flow redirection in piping systems. Its key feature lies in achieving robust pipeline connections via flanges while maintaining the compactness of a standard angle valve.

2. Structural Components

• Valve Body: Typically crafted from stainless steel (e.g., 304/316L), brass, or cast iron for corrosion resistance and mechanical strength.

• Flange Interface: Standard flanges (e.g., DN15-DN100) compliant with GB (China), DIN (Germany), or ANSI (USA) standards, ensuring compatibility with piping systems.

• Valve Trim: Ceramic or stainless-steel trim for high sealing performance and wear resistance.

• Actuation Mechanism: Options include handwheel, gear operator, or pneumatic/electric actuators for manual or automated control.

II. Core Advantages

1. Secure Connection

Flange connections provide superior resistance to high pressure and vibration compared to threaded connections, making them ideal for industrial pipelines and steam systems.

2. Space Efficiency

The 90-degree design minimizes installation space, particularly suitable for tight layouts (e.g., equipment bypasses, corner installations).

3. Pressure and Temperature Resistance

• Pressure Range: Typically supports 1.6–6.4 MPa, with high-pressure variants exceeding 10 MPa.

• Temperature Range: -20°C to 220°C (material-dependent), with stainless-steel models suitable for high-temperature steam.

4. Sealing Performance

Soft seals (e.g., PTFE) or metal-to-metal seals ensure low leakage rates (ANSI Class VI), meeting stringent operational requirements.

5. Maintenance Convenience

Flange connections allow quick disassembly without cutting pipes, simplifying valve replacement or internal repairs.

III. Application Scenarios

1. Industrial Applications

• Steam Systems: Controls high-temperature steam flow in boilers and heat exchangers.

• Chemical Processing: Handles corrosive media (requires 316L stainless steel or specialized coatings).

• Water Treatment: Regulates water flow direction to prevent backflow contamination.

2. Commercial and Residential Use

• HVAC Systems: Manages cooling water or refrigerant circulation.

• Fire Protection: Acts as zoning control valves for rapid response.

• Domestic Plumbing: Connects to water heaters, toilets, etc., for independent shutoff.

IV. Selection Guide

1. Material Selection

• 304 Stainless Steel: Versatile for neutral media (water, oil, gas).

• 316L Stainless Steel: Resists chloride corrosion in marine or chemical environments.

• Brass: Cost-effective but limited to low-pressure water systems.

• Cast Iron: Economical choice with anti-corrosion linings for low-pressure applications.

2. Connection Standards

• Verify pipeline flange standards (e.g., GB/T 9119, DIN 2501, ANSI B16.5) to ensure valve compatibility.

• Select flange sealing face types (flat, raised, or tongue-and-groove) to prevent leaks.

3. Performance Parameters

• Nominal Diameter (DN): Choose based on flow requirements (e.g., DN15-DN100).

• Pressure Rating: Select a rating higher than the system’s maximum pressure (e.g., PN16, PN25).

• Temperature Range: Ensure material compatibility with media temperature.
