Large Butterfly Valve is a kind of butterfly valve, which can be divided into pressure maintaining type, locking type and energy storage type.
The Hydraulic butterfly valve is suitable for the outlet of water pump and the inlet pipeline of water turbine. It is used as a closed-circuit valve and check valve to avoid and reduce the backflow of medium in the pipeline system and produce excessive water hammer, so as to protect the pipeline system.
Today the hammer Hydraulic butterfly valve will be introduced.
Hammer Hydraulic butterfly valve has high degree of automation. It can be controlled locally, remotely and in linkage. It can use PLC intelligent control system to realize text, touch screen and other user-friendly operation interfaces.

1.The hammer large butterfly valve can store energy by itself or by two accumulators. When there is no external energy, it can automatically close the valve.
2.The hammer Large butterfly valve valve can replace the stop valve and check valve at the outlet of water pump, and integrates mechanical, electrical and hydraulic functions, with small floor area.
3.The hydraulic system has the advantages of small motor power, high working efficiency, good pressure maintaining performance and long starting interval of oil pump.
4.The hammer Large butterfly valve valve has obvious opening indication and mechanical limit adjustment mechanism, and the travel switch device is waterproof and dustproof, with stable performance and long service life.
5.The hammer Large butterfly valve can realize linkage operation with other pipeline equipment according to predetermined procedures.
6.When the hammer Large butterfly valve is closed, it can realize slow closing function, effectively eliminate the harm of water hammer, and protect the safety of water pump and pipe network.
