D743H Quick Closing Valve product details

D743H Quick closing valve product description

D743H Quick closing valve produced and sold by Baigang valve group are mainly used in turbine extraction pipelines, blast furnace gas pressure generating device into the gas pipeline and other high-level safety control system for urgent emergency off valve: in the system crisis conditions or accidents, in 0.3-0.5 Seconds to try an emergency off the moment the valve to achieve a reliable medium for the pipeline to effectively prevent the steam turbine tail steam and condensate back or cut off the gas pipeline to protect the safety turbine unit. The introduction of this product to introduce advanced foreign fast shut-off valve function, and technical optimization and improvement, additional buffer device to avoid inertial impact, product performance more reliable, and extend the service life of the valve.

D743H Quick closing valve features
1, using the optimized three-dimensional structure of the eccentric metal seal, high temperature anti-jamming, open and close easily and completely avoid the traditional metal seal contacting the valve abrasion ills;
2, reliable sealing, zero leakage seal test;
3, direct Rack and pinion piston drive, compact structure, 3 ° closed buffer design, constant torque opening and closing, reliable action;
4, integral or split electro-hydraulic control device, easy installation.
