Product Overview flange connection, electric flange shutoff valve [J941H], cut-off valves are suitable for nominal pressure PN1.6 ~~ ??16MPa, working temperature -29 ~ 550 ℃ petroleum, chemical, pharmaceutical, fertilizer, power industry and other The condition of the pipeline, cut off or connected to the line media. Manual, gear, electric, pneumatic driven approach. Electric flange structural characteristics of the shut-off valve, a selection of elegant, in line with domestic and foreign standards, reasonable structure, beautiful shape. 2, the valve seat sealing surface iron based alloy or stellite (Stellite) cobalt-based alloy cladding made of wear-resistant, high temperature resistance, corrosion resistance, anti-abrasion performance and long service life . 4, the valve stem through conditioning and surface nitriding treatment, good corrosion resistance and scratch resistance. 5, can be used with standard pipe flanges and flange sealing surface types to meet a variety of project needs and user requirements. 6, the range of body materials, packing, gaskets under actual working conditions or user requirements reasonable matching, can be applied to all kinds of pressure, temperature and medium conditions. 7, pour seal with threaded connection seal seat or body welding of austenitic stainless steel made, reliable sealing, replace the packing in the case of stopping the machine, convenient, does not affect system operation. With DZW series multi-rotary electric device has a housing small, lightweight, full-featured, and supporting the use of the remote computer, optional electric device according to user requirements.
