Groove Butterfly Valve LWBV-7

1. Small and light, easy to disassemble and repair, and can be installed in any position.

2. The structure is simple and compact, and the 90° turn to open and close quickly.

3. The operating torque is small, labor-saving and lightweight.

4. The flow characteristics tend to be straight, and the regulation performance is good.

5. The number of opening and closing tests is as many as tens of thousands, and the service life is long.

6. Achieve complete sealing and zero gas test leakage


1. Quickly adopt the groove clamp connection and the corresponding pipe fittings to install the pipeline, no welding, no need for secondary galvanizing and secondary installation during construction. Increased the placement rate.

2. Lightweight The clamp connection is light in weight, the number of bolts is small, and the installation is convenient. No special skills are required.

3. Reliable Scientific and fair organization design, unique C-shaped rubber sealing ring, and triple seal to ensure the reliability of the connection seal.

4. Safe use of grooved clamp connection and corresponding pipe fittings placement start, only mechanical assembly, no welding, no open flame, therefore, there is no welding slag turbid pipeline, which can ensure the safety of the construction site and start construction under the conditions of prohibition of fire. , Especially suitable.

5. Economy Because the resettlement is quick, no special skills are required, and the resettlement repair rate is low, the comprehensive resettlement cost can be reduced by 30-50% compared with flanges.

6. Small space occupied. The grooved clamp connection and connection occupies about 70% of the space of the flange, and because the number of fastening bolts is small and non-objective, it is especially practical to start under the condition of narrow space.

7. Simple maintenance. Safe and reliable product quality, as long as the pipeline is properly installed, the pipeline will pass the pressure test at one time, and the operation is safe. It usually does not need maintenance, and the spare parts do not need to be replaced for decades.

8. Practical pipes are common. Grooved clamp connection can be used to connect all kinds of seamless steel pipes, galvanized steel pipes, welded steel pipes, stainless steel pipes, copper pipes and other metal pipes.

9. The flexible connection of the pipeline can be realized. The flexible grooved clamp is connected to the connected pipeline in a flexible system, which can absorb the length displacement of the pipe due to temperature changes and allow the pipe to have a certain offset angle.
