Heavy hammer hydraulic butterfly valve triple eccentric type

The heavy hammer type hydraulic control butterfly valve is an important subdivision type of hydraulic control adjustable butterfly valve. It takes the hammer potential energy as the core energy storage and valve closing power, integrates hydraulic control technology and butterfly valve structure advantages, and has multiple functions of cut-off, check and precise regulation, making it a key equipment to ensure the safe and stable operation of the pipeline system. The valve has prominent core characteristics, with safety redundancy design. Driven by the potential energy of the hammer's gravity, it is independent of the power grid and hydraulic station. In case of power failure or pressure loss, it can automatically close according to the preset program in milliseconds.

1.Intelligent buffering with excellent protection: 

The hammer butterfly valve adopting a "fast front closing, slow back closing" timing logic to perfectly eliminate water hammer effects and protect pipelines and core equipment; The closing angle and fast/slow closing duration can be set as needed to adapt to different working conditions.

2.Reliable sealing and long service life: 

This hydraulic butterfly valve adopting a multi-level combination of soft and hard seals to achieve bidirectional zero leakage; The valve body and valve plate are made of high-strength alloy material, which is suitable for harsh environments such as high pressure, strong corrosion, and high particle media. The maintenance cycle is long and the operation and maintenance cost is low.

3.Reasonable structure and wide adaptability:

The valve body is installed horizontally, and the sealing forms are divided into metal hard seal and rubber soft seal, matched with corresponding eccentric structure, with low flow resistance and low energy consumption; The hydraulic station can be installed as a whole or separately, with automatic pressure holding function, and the pressure holding time can reach more than 168 hours.
