Recently, a batch of extended stem 304L stainless steel sluice gates has successfully passed full-range factory inspection and been delivered to the overseas client’s project site. This batch covers multiple sizes including DN300×300 and DN300×160. The customized extended stem design and outstanding anti-corrosion performance win high recognition from overseas buyers. 

Why do overseas water treatment, municipal drainage and chemical projects choose extended stem stainless steel sluice gates? Conventional sluice gates are limited by installation elevation and liquid level, making it difficult to arrange operation platforms. Equipped with extended connecting stems, this type of sluice gate moves the handwheel actuator to ground-level operating area. Operators do not need to work inside deep manholes or wade in water, greatly improving daily maintenance safety.

The gate body is manufactured from 304L low-carbon stainless steel. The low-carbon composition prevents intergranular corrosion after welding, so the gate remains stable when exposed to sewage and weak acid & alkaline media for decades. Precision machined sealing surfaces guarantee tight shut-off and low leakage rate. The segmented extended connecting rod allows length adjustment on site, perfectly fitting deep tanks, underground pipe trenches and sealed enclosures. The optimized structure resists jamming from suspended solids inside fluid.

Compared with cast iron sluice gates, 304L stainless steel models feature lighter weight and superior rust resistance. Service life is significantly prolonged in coastal salt spray areas and chemical wastewater projects. The matched handwheel drive eliminates the need for underground operation platforms, cutting civil construction investment for contractors. Every unit goes through strict tests including visual inspection, hydrostatic sealing test, stroke calibration and assembly verification in line with international industrial standards, ensuring smooth on-site installation and commissioning.

Our extended stem stainless steel sluice gates are widely adopted in overseas municipal water supply & drainage, wastewater treatment plants, seawater desalination projects, chemical fluid transmission and pump station interception works. Customized stem length and diverse actuators including manual handwheel and electric drive are available according to working depth, medium property and pressure parameters. We keep supplying reliable fluid cut-off solutions for engineering projects all over the world.
