ZH300X Slow Closing Check Valve
ZH300X slow-closing check valve designed by Dazhong Valve Group, hydraulic control valve is generally divided into two categories: diaphragm type and piston type, both of which work on the same principle. It consists of a main valve and its externally installed needle valve, pilot valve, conduit and pressure gauge, etc., and evolves into a remote control float valve, pressure reducing valve, and slow-closing check valve according to the purpose, function and location of use. , flow control valve, pressure relief valve, hydraulic electric control valve, fixed water level valve, water pump control valve, differential pressure balance valve, emergency shutdown valve, etc.
Hydraulic control valves are generally divided into two categories: diaphragm type and piston type, both of which work on the same principle.
It is composed of a main valve and its external needle valve, pilot valve, conduit and pressure gauge, etc., which are combined with the purpose of use.
Evolves into remote control float valve, pressure reducing valve, slow-closing check valve, flow control valve, pressure relief and pressure holding valve, hydraulic electric control valve, fixed water level valve, water pump control valve due to different functions and places , differential pressure balance valve, emergency shut-off valve, etc.
The valve can be installed vertically or horizontally in the pipeline.
The hydraulic control valve is powered by the upstream and downstream pressure difference, controlled by the pilot valve, so that the diaphragm hydraulic differential operation is completely automatically adjusted by the hydraulic power, so that the main valve disc is completely opened or completely closed, or in the Adjust the status.
The check valve with opening and closing speed control can be adjusted to the optimum opening or closing speed when starting or stopping the pump.
It can be used in high-rise buildings to reduce water hammer and water noise, so as to achieve the effect of quiet closing.
