Gate Valve Ss 304

‌304 stainless steel gate valve‌ is a cut-off valve made of ‌304 austenitic stainless steel‌ as the main material. It controls the flow of pipeline media through the vertical lifting of the gate. It has both corrosion resistance and high sealing performance and is widely used in chemical, energy, water treatment and other fields. Its core features and functions are as follows:

Structural composition
‌Core components‌

‌Valve body and valve cover‌: 304 stainless steel casting or forging, temperature resistance range -20℃~425℃, suitable for acid and alkali medium environment; ‌Gate‌: divided into wedge-type single gate (rigid seal) or parallel double gate (elastic compensation), the sealing surface can be welded with hard alloy to improve wear resistance; ‌Valve stem‌: surface polishing or nitriding treatment, linked with handwheel/actuator through trapezoidal thread, supports manual or electric operation; ‌Sealing system‌: stuffing box uses flexible graphite or PTFE material, valve seat and gate are matched with bevel seal, leakage level reaches ISO 5208 standard.
‌Assisted Design‌

‌Filter‌: Prevent impurities from blocking the gate (applicable to scenarios with particle-containing media); ‌Bypass Pipe‌: Balance the fluid dynamic resistance during high-pressure gas transportation.

Application and Function

 Chemical Industry
Application Scenario: Hydrochloric acid and sulfuric acid dilution pipelines;

Core Value: Through corrosion-resistant valve body and sealing surface protection technology, the problem of frequent valve replacement caused by medium corrosion is solved.
 Water Treatment and Municipal
Application Scenario: Sewage treatment plant, seawater desalination system;

Core Value: Full-bore design and anti-clogging structure avoid sediment deposition and ensure high flow rate transmission efficiency.
 Energy and Electricity
Application Scenario: High-temperature steam pipeline (≤425℃);

Core Value: The gate self-compensation seal design at high temperature prevents leakage risk caused by thermal expansion.
 Food and Pharmaceutical
Application Scenario: Aseptic fluid control system;

Core Value: 304 material is FDA certified, and the surface polishing treatment (Ra≤0.8μm) avoids medium contamination.
