H142X hydraulic level control valve Product Description 

 H142X hydraulic level control valve is an automatic control of water tanks, cooling tower liquid level of the hydraulic control valve. When the water dropped by more than the default value, the float valve opens, the piston chamber pressure is reduced, the piston down the formation of pressure in the open under differential pressure valve for water supply operations; when the water level rises to a preset height, float valve closed, the piston chamber pressure is increasing resulting in valve valve to stop water supply. This set forth a high level in the automatic control, automatic water supply function. The product is suitable for industrial and mining enterprises, various civil tank (pool), water towers automatic water supply system. And recycling water used for boiler pressure control valve. 



 H142X working principle of the hydraulic level control valve 

 When the water level inside the tank or water tower fell, the ball float drain opening when the water pressure within the inlet valve piston will hold up, the sealing surface of open water supply valve is opened, when the water level rises to the control valve, float valve closed , the piston sealing surface will be closed down, the valve will stop water supply. 

 H142X parameters of the hydraulic control valves for water 

 Use of media: clean water 
 Working pressure: H142X-4T-A, H142X-4-A: 0.05MPa ~ 0.4MPa 
 H142X-10-A: 0.05MPa ~ 1MPa 
 Medium temperature: ≤ 60 ℃ 

 H142X performance characteristics of the hydraulic level control valve 

 1, control the use of hydraulic principles, the new structure is reasonable. 
 2, smooth and reliable. The use of the specified pressure range, can ensure the impact of water hammer. 
 3, light weight, small size. 
 4, installation and maintenance. 

 H142X hydraulic level control valve installed in the form and notes 

 The vertical fixed in the inlet valve, then the control pipe, valve and float valve connecting the valve can be tightened. The valve inlet and outlet connection flange H142X-4T-A for the 0.6MPa standard flange; H142X-10-A to 1MPa standard flanges. Inlet diameter should be greater than or equal to the nominal diameter of the valve, ball valve outlet should be below. Float valve should be installed in more than one meter from the pipe; in the tank outlet pipe above the water line at the drill a small hole to prevent direct air return. Use, the cut-off valve should be open, like a pool over the valve should be installed two to keep the same level. Lag due to the main valve float valve to shut off about 30 to 50 seconds, so the tanks have enough spare capacity to prevent overflow. In order to prevent impurities, caused by the work of sand into the valve failure, valve should be installed filters. If installed in the underground tank should be installed in the underground pump station alarm device.
