In industrial pipeline systems, check valves play a crucial role, with their core function being to prevent the backflow of media and ensure the safe and stable operation of the system. The H46 series butt-weld double-leaf swing-up flanged check valve, with its innovative design, outstanding performance, and high reliability, has become an ideal alternative to the traditional long-structured flanged check valves, and is widely used in various demanding working conditions.
Compliant with international standards, with excellent quality and reliability
The H46 series check valve strictly follows a series of international and industry standards to ensure that its entire process from design and manufacturing to testing and inspection meets the highest quality requirements:
Design and manufacturing: JB/T 8937
Structural length: DIN 3202, JB/T 8937
Pressure-temperature grades: ANSI B 16.34, DIN 2401, GB/T 9124, etc.
Testing and inspection: JB/T 9092
Pipeline flanges: Compatible with various flange standards such as JB, GB, HG, SH, ANSI, DIN, ASME, etc., with excellent interchangeability and adaptability.
Revolutionary structural features
Compared with traditional check valves, the H46 series has achieved several breakthrough improvements:
1. Ultra-short structure length: Its structure length is only 1/4 to 1/8 of that of traditional flanged check valves, significantly saving installation space.
2. Lightweight design: The weight is only 1/4 to 1/20 of that of traditional flanged check valves, reducing pipeline load and making transportation, installation, and maintenance more convenient.
3. Quick closure, reduced water hammer: The valve disc has a short stroke and adopts a spring-assisted closing mechanism. The valve disc closes quickly, effectively significantly reducing the water hammer pressure generated during closure, protecting the pipeline system from shock damage.
4. Flexible installation: No need to consider the installation direction. It can be installed on horizontal or vertical pipelines, and due to its light weight, usually no additional support frames are required.
5. Extremely low flow resistance: The flow path is smooth and smooth, with a flow resistance coefficient as low as 2.6 to 2.7, and the coefficient further decreases as the valve diameter increases, helping to reduce system energy consumption.
6. Excellent sealing performance: The valve disc moves sensitively and can achieve tight closure with the assistance of a spring, ensuring zero leakage.
7. Compact overall structure: Adopting an integrated design, the structure is simple and compact, with an attractive appearance, combining functionality with modern industrial aesthetics.
Core value brought by outstanding performance
High efficiency, energy saving and cost reduction: The extremely short structure and lightweight weight bring great convenience to the installation, transportation, storage and pipeline layout of the valve, while also saving a large amount of materials and installation costs for the pipeline system.
High reliability and long service life: The valve has a low impact force when closed and a low water hammer pressure. Coupled with the precise internal structure, the H46 series has an extremely long service life and high operational reliability.
Low opening pressure: The valve disc can be fully opened under a very small pressure difference, ensuring that the system can start easily and operate efficiently.
Summary
The H46 series of wafer double-valve swing-up flange check valves is a remarkable achievement in modern fluid control technology. It addresses the drawbacks of traditional check valves, such as their heaviness and space-consuming nature, through its compact design. Moreover, it effectively mitigates the hazards of water hammer by means of spring-assisted closure and the double-valve swing-up structure. Whether from the perspective of space savings and cost reduction, or from the aspect of enhancing system safety and reliability, the H46 series is the preferred component for pipeline system construction in numerous industries such as petroleum, chemical engineering, power, water supply, and construction.
