Product Description

H74 Stainless Steel Wafer-Type Single-Disc Check Valve
Product Description

Introducing the H74 stainless steel wafer-type single-disc check valve - an engineering marvel in valve design, perfect for space-limited installations. This ultra-compact valve combines a sleek structure with dependable performance, offering unparalleled versatility. Here's an in-depth look at its features and capabilities:

1. Structural and Design Features
- Ultra-Thin Profile: This valve's slender form, with a structural length only 1/4~1/8 of traditional flange check valves and significantly reduced weight (approximately 1/4~1/20 of conventional valves), ensures effortless installation and maneuverability in confined areas.
- Single-Disc Swing-Type Design: Featuring a sophisticated single disc with an integrated O-ring seal and spring-assisted closure, it guarantees swift responsiveness, superior sealing, and rapid closure, effectively minimizing water hammer effects.
- Flexible Installation: Designed for seamless horizontal or vertical mounting without the need for additional supports, this valve adapts effortlessly to a variety of pipeline configurations.



2. Technical Specifications
- Nominal Diameter: Ranging from DN50 to DN1000, this valve accommodates an extensive range of pipeline sizes with ease.
- Pressure Rating: With a rating of PN10~PN40 (GB standard) or 150Lb~300Lb (ASME), this valve supports a maximum working pressure of 4.0MPa, ensuring robust performance under demanding conditions.
- Temperature Range:
- Hard-sealed valves: Capable of handling temperatures up to 400°C, perfect for high-temperature applications.
- Soft-sealed valves (e.g., rubber): Suitable for temperatures ranging from -29°C to 250°C, depending on the sealing material, catering to various operational needs.
- Test Pressure:
- Shell test pressure: Rated at 1.5 times the nominal pressure, ensuring structural integrity.
- Seal test pressure: Rated at 1.1 times the nominal pressure, guaranteeing dependable sealing performance.



3. Material and Sealing Performance
- Body Material: Constructed from stainless steel (304, 316, 316L), carbon steel (WCB), or copper, this valve offers exceptional corrosion resistance, making it suitable for a plethora of media.
- Sealing Materials: Options include nitrile rubber (NBR), fluororubber (FKM), EPDM, or PTFE. Hard-sealed variants employ stainless steel, ideal for aggressive media such as acids, alkalis, oils, and steam.



4. Applications
- Compatible Media: This valve is engineered to handle water, oils, steam, acidic/alkaline fluids like sulfuric and hydrochloric acid, and strong oxidizers such as aqua regia.
- Typical Use Cases: It excels in urban water supply/drainage, petrochemical industries, metallurgy, firefighting systems, power stations, and pharmaceutical industries, where preventing backflow is crucial.



5. Key Advantages
- Low Flow Resistance: Its smooth flow passage ensures minimal pressure drop during valve operation, significantly reducing energy consumption.
- High Reliability: The robust, compact design minimizes closing impact, promising extended service life and reduced maintenance needs.
- Customization Options: Available in multiple models (e.g., H74H, H74W, H74X) to meet diverse sealing requirements and comply with international standards (GB, ASME).
