SJ sliding gate valve(resilient wedge gate valve)
S J Slide gate valves are linear motion valves used for full-bore fluid flow without any directional changes. They are designed to provide an effective way to control the flow of free-flowing dry bulk materials. They are mainly used in pipelines such as crude oil, natural gas pipelines, petrochemical oil depots, etc. in industrial processes, and are ideal valves for conveying and interrupting fluid movement. The surfaces of this type of valve are mostly parallel, so they are often called parallel slide gate valves. They are usually fully open or fully closed and are not usually used to regulate flow. However, slide gate valves can also be installed at the outlet of oil pumps to regulate and control the flow of liquids.

Slide gate valve: Structural features
- Embedded RPTFE and specially processed valve seats provide soft and hard double seals.
- The valve seat and seal are equipped with grease injection valves. In case of seal failure, online emergency auxiliary seals can be achieved.
- Triple seal protection (soft, hard, grease injection) makes the seal more reliable, reduces leakage to absolute zero, and provides a longer service life.

Summarize
This high‑pressure slab gate valve is specially engineered for harsh working conditions in oilfield, natural gas and petrochemical pipeline systems. Manufactured with WCB carbon steel material, it delivers outstanding pressure‑resistant performance under high‑pressure working conditions. Equipped with reliable metal‑to‑metal sealing structure, the valve realizes zero‑leakage shut‑off, and supports manual handwheel operation for simple on‑site control. Flange connection provides stable installation, and the anti‑sulfur optional design adapts to medium containing sulfur. Widely applied in oil & gas transmission pipelines, gathering stations, refineries and heavy‑duty industrial piping, this slab gate valve ensures long‑term stable service, easy maintenance and high‑safety pipeline isolation.
