| | Advanced pressure seal design. (See page 10 for details.) No penetration of hinge pin to outside. Eliminates pin seal leakage and provides in-line service. Compact cage unit. All moving parts are attached to the carrier and can be removed easily for service. Forged seat/disc is Stellited, ground and lapped to a mirror finish for maximum erosion resistance and long service life. It is seal-welded to the body. Disc can partially rotate for tight shutoff. In the fully open position, it rests against a stop. Stellite bearings for hinge pin. Easy in-line service. All parts are easily accessible for maintenance. Seating faces can be re-lapped. Forged bonnet. | | |
