The products are summed up:
It can be on the foundation of foreign advanced technology that our factory introduces , adopt the accurate J elasticity to seal enclosing and hard sealed structure of three partial multi-level metal, used in medium temperature ≤managing the gold of 425 degrees Centigrade extensively
, electricity , petrochemical industry , and gives draining off water and urban construction etc. on the industry pipeline, make the flow of regulating and break fluid use in year. Valve this adopt three partial structure, valve between flat and disc board seal adopt different hardness and stainless steel make, there is the good one that is able to bear corrosivity , have long performance life, this valve of two-way sealed functions of field mail, the products accord with the experimental standard of national GB/T13927-92 valve pressure. |
Characteristic of the products:
1, this valve adopts three partial sealed structure, valve seat and butterfly's board have not almost been worn and torn, cross the sealed function with the more urgent view.
2, seal and enclose and select the stainless steel for use to make, have metal hard sealing and double advantage with sealed elasticity , no matter in a situation that it is low and gentle and high-temperature , have a fine sealing property , corrosion-resistant, characteristic of having long performance life etc..
3, disc board seal piece is it is it weld cobalt base hard alloy to pile , seal wear-resisting to decrease to adopt, have long performance life.
4, butterfly's board of the heavy specification adopts Hang's shelf structure, the intensity is high, is it flow area to be heavy to pass, is it hinder little to shed.
5, valve this have two-way sealed function, when installing the restriction that the medium flow into, free of the space position too , can install in any direction .
6, the drive can be installed in many worker's location (rotates 90° or 180°), benefit user's use. |
