KS Stainless Steel Screwed Bonnet Gate Valve
Technical Requirement:
- Design & Manufacture: KS B 2361
- Face-to-Face: KS B 2361
- End Flanges: KS B 2361 (10K Flange Standard)
- Inspection & Test: KS B 2304
Description
The KS Stainless Steel Screwed Bonnet Gate Valve is a high-performance isolation valve designed for corrosive and high-purity applications where space is limited. Manufactured from SCS13 stainless steel, it withstands aggressive media like nitric acid. The screwed bonnet design facilitates a compact profile, while the rising stem mechanism offers clear visual indication of flow status. It is tested to KS B 2304 standards to guarantee safety and reliability.
Technical Specifications:
- Pressure Class: 10K (Approx. 10 kgf/cm² / PN10)
- Size Range: DN40 – DN100 (1.5″ to 4″)
- Applicable Medium: Water, Oil, Gas, Nitric Acid, and Corrosive Liquids
- Operating Temperature: ≤ 150°C
Main Parts and Materials:
| Parts Name | Materials |
| Body, Bonnet | SCS13 |
| Disc | SCS13 |
| Stem | STS304 |
| Packing | PTFE |
Key Product Features:
- Space-Saving Screwed Bonnet: The valve body and cover are connected by screw threads, significantly reducing the overall height and weight of the valve.
- Corrosion-Resistant Construction: Made from SCS13 (SS304) stainless steel, providing excellent resistance to rust and chemical corrosion.
- Rising Stem Design: The stem rises as the valve opens, providing a clear visual indication of the valve position for operational safety.
- PTFE Stem Packing: High-quality PTFE packing ensures a tight seal around the stem, preventing leakage and reducing friction.
- KS Compliance: Manufactured and tested in strict accordance with KS B 2361 and KS B 2304 standards.
Applications:
Ideal for Chemical Processing, Marine Applications, Pharmaceutical Manufacturing, and Compact Piping Systems. Specifically suited for pipelines carrying nitric acid or corrosive liquids where a low-profile valve design is required.
The body and bonnet are connected by a screw thread, which keeps the valve height low and saves space.
