Gate valve is one of the most widely used valves in various fluid transportation projects. 

This valve is an elastic seat sealed gate valve widely used in water supply and drainage pipeline systems in industries such as power, hydraulic, chemical, and urban construction, as an opening and closing or regulating device for controlling medium flow.

This valve is a rubber sealed gate valve widely used in water supply and drainage pipeline systems in industries such as power, hydraulic, chemical, and urban construction, as an opening and closing or regulating device for controlling medium flow.

Used for cutting off, connecting, and regulating media in pipelines, it has good fluid control characteristics and sealing performance, and is widely used in pipelines for corrosive media such as metallurgy, electricity, petroleum, chemical, air, gas, combustible gases, and water supply and drainage.

Soft sealed threaded gate valves and soft sealed threaded locking gate valves utilize the overall rubber coating of the gate plate to achieve good sealing effect, overcoming the problems of poor sealing, water leakage, and rust in general gate valves, and more effectively saving installation space.

Soft sealed threaded gate valves and soft sealed threaded locking gate valves overcome the problems of poor sealing, water leakage, and rust in general gate valves,and can be widely used in tap water, sewage, construction, petroleum, chemical, food, medicine, textile, power, energy systems, etc.

Used for cutting off, connecting, and regulating media in pipelines, it has good fluid  control  characteristics and  sealing performance, and  is applied to corrosive pipelines such as metallurgy, electricity, petroleum, chemical, air, gas, combustible gases, and water supply and drainage.

This series of butterfly valves adopts a medium line design, and its main structure consists of valve body, valve disc, valve seat, valve stem, and transmission operating mechanism. 

The silent check valve is mainly composed of main components such as valve body, valve seat, guide body, valve disc, bearing, and spring.

The double disc check valve mainly consists of important components such as valve body, valve disc, valve stem, and spring, and adopts a thin and lightweight design.

This series of micro resistance slow closing butterfly check valves adopts a slanted disclarge eccentricity design and a double eccentricity structure. At the same time, there is a graded buffer oil cylinder that can achieve two-stage closure, achieving the best effect of eliminating water hammer.

The detachable LoRa remote water meter has significant advantages in real-time monitoring, automatic meter reading, water leakage prevention and cost saving, and is suitable for a variety of water resource management and smart water meter application scenarios.
