With the continuous development of modern high-rise buildings and the increasingly high requirements of each user, our company has successfully developed the second generation of dual-control room multi-function hydraulic control valve on the basis of the first generation of hydraulic control valve in combination with the actual situation.It can be used according to the environment is different, after using the predecessors for one-off adjustment, can automatically ensure the safe operation of pipeline, valve body by using linear design flow, all castings are made to rust pensu processing, all moving parts adopt anticorrosion material, external all conduit and the pilot valve adopts full copper or stainless steel material, after assembled valves do not need to spray paint processing.All surfaces in contact with the medium have good corrosion resistance.By changing the joint form of external guide valve and conduit, it can be evolved into water level control valve, pressure reducing valve, noise suppression/hammer/slow opening/slow closing check valve, safety relief valve, electric remote control valve, etc.
According to the use of different media and pressure, we produce piston type and diaphragm type for users to choose.The main characteristic of this kind of valve is to control the opening and closing of the main valve disc by using the pressure difference of the upper and lower chamber control room in the pipeline.
1. It has the function of slow opening, which can solve the traditional manual valve closing and pump starting
2. With the function of slow closing, the closing time can be set manually to automatically realize slow closing and eliminate water hammer
3. It has good check function. It uses rubber with good elasticity and high wear resistance as the sealing material, which can achieve no leakage after closing.
4. The action is sensitive and will not be out of control.
5. Without manual operation, it works automatically in the whole process of pipe network operation.
6. It is convenient to maintain and repair. It is not necessary to remove the whole valve from the pipeline. It is necessary to find out the cause of the fault during the repair, and only need local maintenance.
7. The inside and outside of the valve and all easily corroded parts are treated by electrostatic spraying, which will not rust in sewage for a long time.
8. In the pipeline, the installation performance remains unchanged.
