Bolaisi stainless steel gate valves are made of high-quality 304 or 316 stainless steel with high purity and low impurity content. They can effectively resist corrosion from air, moisture, acid and alkali solutions, and other media, completely avoiding rust, corrosion and aging of the valve.
The valves operate stably without damage in corrosive raw material pipelines in the chemical industry, as well as in seawater desalination, shipbuilding and other environments exposed to salt spray for a long time. Compared with ordinary carbon steel valves, the service life of stainless steel gate valves can be extended by 2–4 times, greatly reducing users’ replacement costs.
Bolaisi also provides stainless steel ball valves with equivalent corrosion resistance, which can be used together with stainless steel gate valves to meet pipeline control requirements under different working conditions and form a complete fluid control solution.
Stainless steel gate valves adopt a precision-ground sealing structure. The valve seat and gate plate fit closely, and the sealing surface is mirror-polished with low roughness and high sealing performance, which can effectively prevent fluid leakage and ensure the safe and stable operation of the pipeline system.
The valves maintain excellent sealing effect under normal temperature and pressure as well as high-pressure environments, without dripping or seepage, avoiding material waste, potential safety hazards and environmental pollution caused by leakage.
This sealing technology has been verified by many industrial tests, and the sealing performance remains stable after long-term use without frequent replacement of sealing parts. This high-quality sealing feature is also reflected in Bolaisi stainless steel globe valves. The two products can be flexibly matched according to pipeline control needs to adapt to more scenarios.
Stainless steel gate valves feature special structural design and heat treatment, providing excellent high pressure and high temperature resistance. They can work stably at a pressure of 0.6–16 MPa and a temperature range of -20°C to 425°C without deformation, cracking or performance degradation.
The valve stem is made of high-strength stainless steel with strong tensile and wear resistance, capable of withstanding the impact of high-pressure fluid and ensuring flexible and reliable opening and closing.
These valves are widely used in petroleum, chemical, electric power, metallurgy, pharmaceutical and other industries, suitable for pipelines conveying steam, oil, high-temperature water, corrosive media and other fluids, making them indispensable control components in industrial pipeline systems.

Stainless steel gate valves feature a compact and simple structure, moderate size and light weight. Installation and disassembly can be completed quickly without complicated tools, greatly improving construction efficiency.
The operation is simple with flexible manual opening and closing, easy to use without professional training. Daily maintenance is also extremely convenient: only regular inspection of the valve status, sealing surface cleanliness and occasional lubrication are required, without frequent disassembly and overhaul, effectively reducing maintenance time and labor costs.
In addition, Bolaisi provides comprehensive after-sales service for stainless steel gate valves and all stainless steel valve products, including installation guidance, fault repair and parts replacement, solving various problems encountered by users in a timely manner.
With stable structure, low failure rate and convenient maintenance, the valves further reduce users’ long-term operating costs and improve the operation efficiency of the pipeline system.
