The role of hydraulic control check valve and features
The role of pilot-operated check valve: The pilot operated check valve is suitable for the outlet pipe of medium-water pump to avoid and reduce the pros and cons of medium in the piping system and produce excessive water hammer to protect the piping system, Its function to a valve on behalf of the two valves (traditional piping design with check valve or non-return valve with a common valve). Hydraulic control check valve features: 1, hydraulic check valve control part of the full hydraulic control form, the accumulator to take the weight of the part, reducing the energy loss, the transmission mechanism is simplified, space-occupying space , Similar to the general type valve. Easy to install, that class left and right horizontal installation, you can also vertical installation. 2, hydraulic check valve installed in the pump, instead of gate valve (valve) and check valve two valves. And the flow resistance coefficient is small, large-diameter valve flow resistance coefficient is only slightly higher than the valve. Therefore, this type of valve for energy-saving products. 3, when the pilot-operated check valve is closed, the time and switching angle of the fast and slow closing sections can be adjusted according to the characteristics of the piping system or the user's requirements, so as to eliminate or reduce the water hammer and protect the system. 4, If all the travel switches are inductive proximity switches, remove the hydraulic station, protection class up to IP67.
