AIRTESER&D-8423 控制阀

Product Description
The valve applies cage-guided, pressure-balanced spool, and is suitable for the occasion where with large pressure difference, the solid cage guide and unique balanced sealing ring offers high stability to the vertical movement of spool and reduces vibration and mechanical noise. The valve with superior dynamic stability is suitable for harsh work conditions. Due to the structure that the fluid pressure is balanced on the spool, the small operation force can attain stable adjustment.
