DISC HARD FACE The standard disc is built with a Stellite weld overlay or Hard chrome plated, hard face provides increased hardness and wear resistance with long service life. SEALING DESIGN The soft sealing of graphite for laminated seat is placed on the body which reducing the possibility of graphite gets wear further leads to leakage. The graphite is positioned in the notch of the sealing seat in order to allow for easy repair. We provides laminated seat, solid metal seat as well. DUST PROOF DESIGN A set of bushing design prevents the ingress of foreign material into the shaft area. SHAFT STRENGTH UPGRADED Shaft strength increased by splined shaft without drilling on the shaft for taper pin. BLOW-OUT PROTECTION Both the shaft stop and bottom cover offers reliable blowout protection. DISC Pin-less design provides easily maintenance work. BI-DIRECTIONAL SHUTOFF DESIGN The floating sealing design is self-adjustable and the sealing surfaces of an elliptical sealing system are completely in contact at the final position only. This mechanism provides flawless bubble tight shutoff. For flanged end valve, the shaft is positioned at the flange side which reduced the possibility of external leakage caused by the ambient temperature changed.
