Large Bore Electric Gate Valve

Let's lay out the parameters clearly, no tricks: the nominal diameter ranges from DN50 to DN400, so it can match both the main water supply pipelines in factories and the main oil pipelines of large equipment; the nominal pressure can withstand 1.6-10MPa, making it stable for working conditions like high-pressure water circulation systems and industrial gas transmission; the applicable temperature range is wide, working normally from -40℃ to 250℃-whether it's low-temperature coolant or medium-temperature steam, it's reliable. It's also compatible with various media such as water, oil, steam, and natural gas, eliminating the need for frequent valve replacements.

 

Its most practical advantage is the "electric drive + gate seal" combination: the motor is a customized high-precision model, with switch stroke controllable to the millimeter level. It can be operated remotely, no need for workers to climb pipes and turn valves manually-saving labor and reducing errors. The gate uses a hard-seal structure, which has low wear; unlike ordinary gate valves that leak after long-term use, its seal life is 30% longer than similar products. If you've used our floating ball valve before, you know how strict Zhengmao is about sealing-and this electric gate valve meets the same sealing standards, with a leakage rate fully complying with Class VI of GB/T 13927, so there's basically no need to worry about medium leakage.

In actual use, its application scenarios are also wide: in the water circulation pipelines of thermal power plants, it controls cooling water flow extremely stably; in the raw material transmission pipes of petrochemical plants, it withstands high pressure and resists corrosion; in the main pipelines of urban heating networks, it opens and closes flexibly even in low-temperature winter environments; even in the large-diameter sewage pipes of sewage treatment plants, it can withstand the impact of impurities and is not easy to clog. Compared with manual gate valves, it has a fast switch speed (3-5 seconds for the whole process) and can be linked to the central control system for automated monitoring-workers don't have to stare at instrument panels and adjust manually, directly improving operation and maintenance efficiency.

We also stand firm on after-sales service-a one-year warranty. Whether you need technical staff to provide on-site guidance during installation, or encounter faults during use, just make a call or leave an online message, and someone will respond 24 hours a day. You won't have to delay production due to valve issues.
