Wafer and Lug K35 / K36 / K37 / K38 - Valve Data

K35/36/37/38 product is high performance valve with double offset application to make flow control easier.

Double Offset Disc /Stem :

• Unique two-piece stem and double-offset design allows for high cycling and creates a lower disc profile with increased capacity and a rangeability of 33:1.
• In addition to increasing flow area across the disc, design minimizes wear points between seat-disc. The first offset is achieved by locating the streams downstream of the center-line of the seat which allows 360 deg. Sealing surface.
• The second offset is achieved by off-center of the vertical axis of the seat.
• The combination of these two offsets creates a camming effect as the disc swings into and out of seat. No wear points between disc and seat.

Features and Benefits :

• Extended neck allows two inches of pipeline insulation.
• Integrally casted mounting flange provides direct mounting of many actuators.
• Disc taper pin are designed to position half in disc and half in stem to eliminate potential failure by placing compression instead of shear.
• Integrally casted disc stopper in body perfectly locates the disc in seat to achieve maximum life of seat and other relevant parts.
• Bore with stem bearing provides max. stem support.
• Gland bridge components for uneven adjustment of gland nuts.
• To make flange face uninterrupted, retainer ring is provided with spiral wound gaskets which provides unidirectional dead-end service as standard.
• Seats are providing bi-directional, drop tight closure in vacuum and throughout all pressure ranges as well full rated differential pressure. Variety of material allows optimum seat life in all applications.
