Product Details
Product Introduction
Stainless steel valves primarily serve to regulate and shut off the flow of process media in piping systems. They can effectively control pressure and flow in high-pressure pipeline networks and offer advantages such as wear resistance, corrosion resistance, excellent sealing performance, and a long service life. When selecting and using stainless steel valves, it is essential to consider factors like manufacturing quality, material, design, and size to ensure safe and stable operation under operating conditions. Additionally, regular inspection and maintenance are required during service to uphold their performance and reliability.
Product Structure
The structure of stainless steel valves primarily comprises the valve disc (ball), valve seat, sealing surfaces, and valve body. It is a general term for sealing components and encompasses numerous types, such as gate valves, globe valves, check valves, ball valves, and more. The structural configurations of these various types of stainless steel valves differ accordingly. Taking the ball valve as an example, its basic structure includes the valve body, valve stem, valve disc (ball), seals, packing, and bonnet, among other parts.
Product Categories
1. Classified by connection method:
Threaded connections are the most common type of valve connection and are suitable for valves with small diameters.
Flanged connections: Available in slip‑on flange and necked‑in butt‑welded flange configurations.
Socket-welded and threaded socket-welded connections: generally suitable for large-diameter valves.
Welded connections: Primarily suitable for valves with large diameters and high pressure ratings.
Wafer connection: Suitable for connecting valves with small diameters.
Clamp connection: a novel rapid‑connection method,
2. Classified by structural form:
Globe valve: Its body is of the straight-through type, hence it is also referred to as a straight‑through valve. Based on the valve’s performance and operating parameters, it is typically designed for pressures ranging from several dozen to several hundred kilograms. The construction may feature either a rising stem or a lever‑type actuator, and the valve can be further classified into ball‑type and cone‑type designs.
Gate valve: It offers excellent sealing performance and is suitable for use in critical pipeline systems.
Butterfly valve: Suitable for on-off control of media in low-pressure pipelines.
Ball valve: Suitable for on-off control of low-pressure pipeline media, featuring quick, precise, tight shut-off, and excellent durability.
Diaphragm valve: A special type of shut-off valve, suitable for various control and distribution systems.
Plug valve: It is easy to maintain and replace, and can handle media containing particles and exhibiting a certain degree of viscosity.
Check valve: Used to prevent backflow of the medium.
3. Classified by manufacturing standards:
GB Standard: Valves manufactured in accordance with the standards of the National Ministry of Machinery Industry.
API Standard: Valves manufactured in accordance with American Petroleum Institute standards.
