Product Description

Product Description

Lock Hopper valves(Generally flanged connection, but Butt-welding optional) are suitable for using on various kinds of pipeline from Class150 To Class1500, PN16 To PN100 to cut off or connect the flowing of medium. By using different material, the valves could be suitable for medium such as water, steam, oil, nitric acid, acetic acid, oxidizing substance, carbamide and etc. Manual/Bevel gear/pneumatic or electric actuators could be chosen by needs. Metal to metal sealed construction, graphite packing and stainless steel or titanium alloy+flexible graphite gasket ensures lock hopper valve a reliable sealing even under fire accident.

Lock Hopper valve is a special metal to metal sealed ball valve designed for the complex working condition of coal gasification which could suit the condition of high pressure & temperature & needing high wear-resistance feature. Lock Hopper valve aims to solve the long existed problem of valve couldn't close/open normally in pipeline of coal slurry feeding & black water process system due to the deposited medium & its wearing influence. So the lock hopper valve is a key valve in coal gasfication system to ensure system's long life span.

Chaoda Brand Flanged Lock Hopper Ball Valve

The spring in lock hopper valve could have a steady elastic performance under high temperature. And unique sealing measures have been done to ensure no ash would exist in spring area to ensure the sealing of ball and the moveable of seat. The hard alloy sealing face with Special scraping function could realize self cleaning while closing or opening the valve to avoid slag remaining on the surface of ball.  Remelting technology has been applied to combine the Ni-based hard alloy sealing material onto the ball and seat ring with a better combining force. Reasonable hardness difference between ball and seat ring ensures the long life span & good sealing effect . Pneumatic with proper torque and reliable air valve, solenoid valve, resersal valve, limit switch, filters and other accessories could be chosen if needed.
