UPVC plastic gate valve DN40 is a widely used fluid control component in acid and alkali resistant pipelines.

The Stainless Steel 316L Non-Rising Stem Gate Valve DN80 is a widely used shut-off device in chemical processing, water treatment, pharmaceutical, and marine industries. Its core advantages are super

lass900 (approx. 15.4 MPa) is a high‑pressure rating per API 6D, widely used in long‑distance natural gas pipelines, compressor stations, and urban high‑pressure ring mains. Such valves must comply

Concentrated sulfuric acid is highly corrosive. Lined gate valves address this by lining all wetted parts—body, gate, and stem—with fluoroplastics like FEP (F46) or PFA. This isolates the metal from

In high‑chloride environments like seawater desalination and offshore platforms, duplex stainless steel (2205/2507) offers superior resistance to chloride stress corrosion cracking and pitting, with

In petrochemical, gas transmission, and pharmaceutical plants, explosion-proof electric gate valves are essential for safe shut-off. CT6 (Exd IIC T6) is the highest protection level – suitable for hy

For liquid nitrogen, LNG, and ethylene services at -196°C, standard carbon steel (WCB) and low‑temperature steel (LCB/LCC) become brittle. Austenitic stainless steel (304/316L) is mandatory.

Hastelloy (C-276/C-22) is the top choice for strong acids (hydrochloric, sulfuric, hydrofluoric), alkalis, and mixed corrosive media. DN65 (2.5″) is common in chemical, pharmaceutical, and hydrometal
