I. Product Overview: 
 Flanged connections for nominal pressure valve PN1.6 ~ 16MPa, operating temperature -29 ~ 550 ℃ oil, chemical, pharmaceutical, fertilizer, power industry and other conditions of the pipe on the road, cut off or connected piping the media. Drive a manual gear, electric, pneumatic, etc. 
 Second, the structural characteristics: 
 1, selected materials, in line with domestic and foreign standards, reasonable structure, beautiful shape. 
 2, valve, valve seat sealing surface using iron-based alloy or stellite welding (Stellite) made of cobalt-based alloy welding, wear-resistant, high temperature resistance, corrosion resistance, anti-abrasion performance and long service life . 
 4, the stem after the quenching and surface nitriding, has good corrosion resistance and scratch resistance. 
 5, can be a variety of standard pipe flanges and flange sealing surface to meet the requirements of various engineering and user requirements. 
 6, the full range of body materials, packing, gaskets according to actual conditions or user requirements reasonable matching can be applied to all kinds of pressure, temperature and medium conditions. 
 7, back sealed with screw connection seal seat or body made of austenitic stainless steel welding, reliable sealing, replace the packing in the case of the non-stop, convenient, does not affect system operation. 
 8, with DZW Series multi-turn electric devices, with the shell is small, lightweight, full-featured, and supporting the use of remote computers, but also matching electrical devices according to user requirements.
