1. Product Overview & Core Advantages

1.1 Product Overview

The CA-FIRE BS5153 Swing Check Valve is a high-performance fluid control device designed to prevent medium backflow in pipelines, fully compliant with British Standard BS5153. As a swing-type check valve, it features a hinge-mounted disc that opens automatically under forward fluid pressure and closes tightly under backflow pressure-ensuring unobstructed forward flow and reliable backflow prevention.

Constructed with premium materials (GG25 cast iron body, brass seats, and 40Cr/2Cr13 mechanical components), the valve is engineered for PN16 working pressure, suitable for water, oil, and non-corrosive media. Available in DN50~DN300 specifications, it is widely used in fire protection systems, industrial pipelines, municipal water supply networks, and petrochemical facilities. The valve's simple structure, robust design, and precise manufacturing guarantee long-term stable operation with minimal maintenance.

1.2 Core Advantages

BS5153 Standard Compliance: Fully meets British Standard BS5153 requirements, ensuring compatibility and qualification for European and global projects adhering to 英标 norms.

Reliable Backflow Prevention: Swing-type disc design with brass sealing seats provides tight closure, preventing backflow even under low differential pressure.

Durable Material Combination: GG25 cast iron 阀体 for structural strength, brass seats for corrosion resistance, and 40Cr/2Cr13 shaft components for wear resistance-adapting to harsh industrial environments.

PN16 High-Pressure Rating: Designed for PN16 working pressure, suitable for medium and high-pressure pipeline systems (compatible with most industrial and fire protection pressure demands).

Wide Size Coverage: Available in DN50~DN300 specifications, fitting diverse pipeline diameter needs from small-scale water supply to large industrial flow.

Easy Installation & Maintenance: Lightweight relative to its size, with clear flow direction markings; simple structure allows easy disassembly and maintenance.

Stable Flow Performance: Swing disc opens smoothly with minimal flow resistance, ensuring efficient fluid transmission without pressure loss.

3. Installation, Operation & Maintenance Guidelines

3.1 Installation Requirements

Flow Direction Alignment: Ensure the arrow marked on the valve body is consistent with the actual fluid flow direction-incorrect installation renders backflow prevention ineffective.

Pipeline Preparation: Install on clean, debris-free pipelines; flush the pipeline thoroughly before installation to avoid damaging the valve seat and disc.

Installation Orientation: Preferred for horizontal pipelines (disc swings vertically); vertical installation is allowed only when fluid flows upward (to ensure disc closure by gravity).

Flange Connection: Use matching flanges and gaskets; torque bolts evenly to ensure tight sealing and prevent leakage under pressure.

Space Reservation: Leave sufficient space around the valve for future maintenance and disc inspection (no obstacles within the disc swing range).

3.2 Operation Notes

Pre-Use Check: Before commissioning, confirm the disc swings freely without jamming; check for debris or corrosion that may affect closure.

Pressure Adaptation: The valve opens automatically when forward pressure exceeds back pressure (no manual operation); avoid overpressure beyond PN16.

Backflow Prevention: In case of system shutdown or pressure reversal, the disc closes tightly under gravity and back pressure to prevent medium backflow.

3.3 Maintenance Tips

Quarterly Inspection: Visually check for leakage at flanges and valve body; verify the disc swings flexibly by manually rotating the axle (after depressurizing the pipeline).

Semi-Annual Cleaning: Disassemble the bonnet to clean the disc, seat, and axle; remove scale, sediment, or debris that may affect sealing.

Sealing Maintenance: Inspect the brass seat and disc sealing surface for wear or scratches; replace damaged seats/discs promptly to maintain leak-proof performance.

Lubrication: Apply anti-rust lubricating grease to the plug axle semi-annually to prevent seizing and ensure smooth disc movement.

Corrosion Protection: For coastal or industrial environments, apply anti-corrosion coating to the valve body surface every 1-2 years; touch up paint on scratched areas.

4. Packaging & Transportation

Packaging: Each swing check valve is wrapped in PE film and foam padding to protect the flange and valve body from scratches. Multiple units are packed in export-grade wooden crates with reinforced corners, suitable for sea/air freight. Each package includes a certificate of conformity and installation instructions.

Transportation: Avoid stacking heavy loads on crates; protect from rain, impact, and mechanical damage during transit. Do not disassemble the valve or strike the disc/axle.

Storage: Store in a ventilated, dry warehouse (-10℃~40℃); avoid storing with corrosive substances or sharp objects. Place the valve horizontally to prevent deformation of the disc and axle.

5. Application Scenarios

Fire Protection Systems: Automatic sprinkler systems, fire hydrant networks, and foam fire extinguishing pipelines (prevents backflow of fire-fighting media).

Industrial Pipelines: Petrochemical, power plant, and manufacturing facility pipelines (controls fluid direction in oil, water, and chemical media).

Municipal Water Supply: Water treatment plants, tap water pipelines, and irrigation systems (prevents backflow of contaminated water).

Commercial & Residential Buildings: Central air conditioning water systems, hot water supply pipelines, and heating networks.

Infrastructure Projects: Railway stations, airports, and port terminal fluid transmission pipelines.

6. Frequently Asked Questions (FAQ)

Q: What standard does this swing check valve comply with?A: It fully complies with British Standard BS5153, meeting the quality and performance requirements for check valves in international projects.

Q: Can it be installed vertically?A: Yes, but only for upward fluid flow-vertical installation with downward flow will cause the disc to fail to close properly. Horizontal installation is preferred for optimal performance.

Q: What is the maximum working pressure?A: The pressure rating is PN16 (1.6MPa), suitable for most industrial and fire protection pipeline pressure demands.

Q: What materials are used for the sealing components?A: The body seat and disc seat are made of brass, which provides excellent sealing performance and corrosion resistance.

Q: How often should the valve be maintained?A: Conduct quarterly visual inspections and semi-annual cleaning/lubrication; replace wearing parts (seats, discs) as needed based on usage conditions.
