First, The Electric Cut-off Valve Overview
The opening and closing of the electric cut-off valve is a plug-shaped disc, sealing surface was flat or cone, the valve flap along the centerline of the fluid for linear motion. The movement of the stem, there are lifting rod (stem lift, hand wheel does not lift), there are lifting and rotating rod (hand wheel and stem together with the lift, the nut is located on the valve body). The electric shut-off valve is only suitable for full and full clearance, and is not allowed for adjustment and throttling. 

Second, The Electric Cut-off Valve Structural Characteristics
1, Selection of sophisticated, in line with domestic and foreign standards, reasonable structure, handsome in appearance. 
2, The valve, the valve seat sealing surface with iron-based alloy surfacing or Stellite (Stellite) cobalt-based hard alloy surfacing, wear, high temperature, corrosion resistance, scratch resistance, long service life.
3, Stem quenched and tempered and surface nitriding treatment, a good corrosion resistance and scratch resistance. 
4, Can be used with a variety of piping flange and flange sealing surface type to meet the needs of various projects and user requirements. 
5, The full range of valve material, packing, gasket can be based on actual conditions or user requirements reasonable matching, can be applied to a variety of pressure, temperature and media conditions. 
6, Inverted seal with a threaded connection seal or body welded austenitic stainless steel, sealed and reliable, replace the filler can be carried out in the case of non-stop, convenient and quick, does not affect the system operation. 
7, Equipped with DZW series of multi-rotary electric device, with a small shell, light weight, full function, and can be used with remote computer support, but also according to user requirements optional electric device.
