Using elements of Hydraulic control valve design are as follows:

(1) the application of engineering-type hydraulic control valve is the result of factory inspection, complete all kinds of identification, technical information to meet the requirements of the product. (2) According to the functional requirements, select the valve type, according to the media pipeline, temperature, building standards and requirements the owners to determine the position of the valve body and sealing materials. Body material commonly used in cast iron, copper, iron, copper, plastic and so on. Commonly used sealing surface and lining material, copper alloys, plastics, steel, alloy, rubber. Body material should be matched with the pipe material. (3) of the valve nominal pressure 4.0MPa are 0.6,1.0,1.6,2.5 and the different levels of the media pipeline, the working pressure should be less than the nominal value of the valve.

(4) engineering hydraulic control valve setting should have enough space for the management, operation, installation and maintenance, and should meet the requirements of the valve pipeline. (5) pipe flange connection, should be used to connect the hydraulic control valve flange; pipe with groove connection, the connection should be used groove hydraulic control valve. (6) hydraulic control valve should be set in the medium one-way flow of the pipeline. (7) hydraulic control Fazhu arrow on the body the flow direction must be consistent with the piping system. (8) hydraulic control valve pipe connection should not have gas block, air resistance phenomenon. The highest location in the network segment should be set to automatically save gas exhaust valve. (9) valve for horizontal installation, valve cover, valve stem should be facing up. Vertical installation, valve cover, valve stem should be facing out. (10) should be done before installing the valve strength and leak test.
