Fujian Mingda has completed the product system reorganization of valve forging components, covering the entire machine's supporting requirements with four main categories: valve body, ball, valve seat, and valve cover, as well as supporting components such as support plates and pressure plates.

Recently, Fujian Mingda Valve Manufacturing Co., Ltd. has systematically reorganized the valve forging component product line, incorporating the four main categories (valve body, ball, valve seat, and valve cover) and supporting components (such as support plates and pressure plates) into a unified product system. The updated information is also available on the company's official website's product center. Users can find the corresponding forging components for the valve parts during the selection stage, without having to inquire about prices separately or repeatedly confirm deliveries.

1. Four Main Categories and Supporting Components

Valve body: The main pressure-bearing component of the valve, the uniformity of wall thickness and internal density directly affect the service life. It is the category with the highest requirements for forging process among the four types of forging components.
Ball: The core component of the ball valve, it requires strict roundness, surface roughness, and dimensional tolerance. The quality of the forging blank directly determines the subsequent processing accuracy.
Valve seat: The key component of the sealing pair, the processing quality of the sealing surface and the material selection directly affect whether the valve can achieve the required leakage level.
Valve cover: Together with the valve body, it constitutes the pressure-bearing cavity. The wall thickness transition at the flange connection part requires a reasonable forging streamline to avoid stress concentration.
Supporting components: Including support plates and pressure plates, structural components can be processed according to drawings or samples, reducing the workload of users' multiple purchases and repeated communication.

2. One-stop Delivery from Forging to Machining

The value of valve forging components not only lies in the blank itself, but also in the precision of subsequent machining. Mingda adopts an integrated delivery method of forging and machining, completing the drawings within one process, avoiding issues such as unclear size responsibility and difficult quality traceability caused by outsourcing the blank for processing.

According to the usual practice, the regular process for customizing based on drawings is as follows: users provide drawings or samples → confirm material and execution standards → calculate forging process and machining allowances → quote and confirm delivery date → material input for forging → heat treatment → machining → inspection → delivery. During the entire process, users can keep track of the current stage and respond promptly to any changes in drawings.

3. Write technical requirements into the contract, and there will be a grip on delivery

Most quality disputes of valve forging components occur due to unclear requirements. The technicians of Mingda suggest clearly stating the following four items before procurement:

Material aspect: Specify the grade, execution standards, and requirements for chemical composition and mechanical properties.
Testing aspect: Indicate the execution standards and qualified grades of non-destructive testing to avoid mismatch between "performed testing" and acceptance standards.
Heat treatment aspect: Specify the delivery state (normalizing, annealing, quenching and tempering, etc.) and hardness requirements.
Processing aspect: Specify whether it contains machining, to what extent it is machined, and whether it requires reserved allowances.

Discussing these items before the quotation will reduce the number of disputes during the acceptance process.

4. Services and Contact

The company has been focusing on the forging production of valve forging components for many years and has accumulated relatively mature process experience. It can customize various valve metal forging components according to drawings or samples, meeting the working conditions requirements of industries such as petrochemical and energy. The model and specification information of the product center is continuously updated, and relevant materials can also be obtained through the download center.

Users with drawings or samples that need to be priced can directly contact Mingda for process assessment and quotation.
