DYQ Top Entry Eccentric Half Ball Valve
The DYQ top-loading eccentric hemispherical valve produced by Dazhong Valve Group adopts the eccentric-tightening principle to achieve the purpose of gate tightening, adjustment and closing through the transmission mechanism. , Different alloys are butt welded on the base metal, and the valve operation corresponding to the butt welding can achieve zero leakage through special treatment to transport harmful gases. The valve core of the sealing pair has a compensation amount. When the valve seat is worn, turn it a little when it is closed, and it can still seal reliably and prolong the service life. In addition, the user can unscrew the compression nut and adjust or replace the valve seat. .
Small pressure loss: zero water loss when fully open, the flow channel is completely unobstructed, and will not deposit in the cavity of the valve body as of now.
Resistance to particle wear: There is a shearing effect between the ball crown of the V-shaped opening and the metal valve seat. During the closing process, the ball crown only leans against the valve seat at the end, no friction is formed, and the valve is closed. The seat is made of wear-resistant nickel alloy, which is not easy to be washed and worn, so it is suitable for fibers, tiny solid particles, pulp, etc.
Suitable for high-velocity media: straight-through flow channel, solid eccentric crankshaft makes it suitable for high-velocity flow without vibration. Long service life: no wearing parts, due to eccentricity, there is no friction between the sealing surfaces when the valve opens and closes. long lasting.
Easy maintenance: the valve does not need to be removed from the pipeline for maintenance, just open the valve cover to carry out maintenance.
