Basic Info.
Product Overview.
With the continuous development of modern high-rise buildings and the water world, as well as the increasing demands of various users, combined with practical situations, the second generation dual control room multifunctional hydraulic control valve has been successfully developed on the basis of the first generation hydraulic control valve. It can automatically ensure the safe operation of the pipeline network after one-time adjustment according to different usage environments. The valve body adopts a streamlined design, all castings are treated with rust removal and spray coating, and all moving parts are corrosion-resistant. By changing the connection form between the external guide valve and the conduit, it can be transformed into a water level control valve, a pressure reducing valve, a sound-absorbing/anti hammer/slow opening/slow closing check valve, a safety relief valve, an electric remote control valve, etc. According to the different media and pressure used, there are two types of products available for users to choose from: piston type and diaphragm type.
The main feature of this type of valve is to use the self pressure inside the pipeline to control the opening and closing of the main valve disc through the pressure difference between the upper and lower chamber control rooms, thereby achieving the goal.

Product features.
With a slow opening function, it can solve the traditional problem of manually closing the valve and opening the pump.
Equipped with a slow closing function, the closing time can be manually adjusted to automatically achieve slow closing and eliminate water hammer.
It has good check function and uses rubber with good elasticity and high wear resistance as the sealing material. After closing, it can achieve no water leakage.
The action is sensitive and there will be no loss of control.
No need for manual operation, it operates automatically throughout the entire process of pipeline network operation.
Convenient maintenance and repair, without the need to remove the entire valve from the pipeline. When repairing, identify the cause of the malfunction and only require partial maintenance.
The inside and outside of the valve, as well as all easily corroded parts, are treated with electrostatic spraying, which will not rust when used in sewage for a long time.
The performance remains unchanged when installed horizontally in the pipeline.
