		DTDA Triple Offset Metal Seated
		Features: 1. The seal is adjustable and replaceable, which prolongs the service life. 2. With the floating seal, the seal ring can properly self-adjust its position by the valve closing press so as to bring the disc in fully contact with the seat and realize an even seal pressure ratio and zero leakage. 3. The triple eccentric structure facilitates an immediate opening or closing with least friction. 4. The position device along the stem eliminates the leaking problem due to the damage or wearing at the upper and bottom seal faces resulted from the up and down axial movement of the disc, which makes it possible to install the actuator in any direction (For the butterfly valves size more than 500mm, we suggest horizontal installation.)
