DYQ340F mounted eccentric globe ball valve

Product Overview: DYQ340F(H) top eccentric half ball valve is in the digestion and absorption of foreign clamping large flow through valve on the basis of successful development, its structure adopts eccentric - compact principle through the transmission mechanism to achieve the purpose of brake tightening, adjustment, closing seal pair is metal surface ring with hard surface contact seal, double eccentric structure in the opening of the valve core is located in the ball room, flow section is large,
And the valve is not washed, the spool is not washed when it is closed, the spool goal is gradually along the valve seat when it is opened, and the structural obstacles are removed to achieve reliable sealing. It is especially effective for mixed-flow transportation of two-phase mixed-flow structure precipitation. Valve hemisphere with bimetal, base metal on the butt welding of different alloys, valve operation corresponding butt welding treatment, sealing surface combination into anti-corrosion, high strength and other types, to meet the needs of different occasions. The third feature is tight seal, the transmission of harmful gases can reach zero leakage, the fourth feature is that the valve core of the sealing pair has a compensation amount, when the seat is worn, and then turn a little when closed, it can still be reliably sealed and extend the service life, in addition, the user will screw off the compression nut, adjust or replace the seat can still be used.
