Cast Steel Wedge Gate Valves

Cast Steel Wedge Gate Valves are generally opened and closed by moving the stem up and down with the rotating handwheel. There are two forms of rising stem and nin-rising stem, rising stem wedge gate valve is the valve stem up and down, the valve stem nut is fixed; The non-rising stem gate valve is the stem fixed, the stem nut moves up and down to complete the opening and closing.

Cast Steel Wedge Gate Valves’s summary

The quality of valves is closely related to their cost. The Z41H16 DN100 cast steel (investment casting, the same below) wedge gate valve designed according to different standards has a weight of up to 52kg and a light weight of only 25kg (theoretical weight, the same below), with a sales price difference of 2-4 times. The purpose and requirement of valve optimization design is to select and determine suitable product standards based on actual working conditions and market price positioning, strictly design according to product standards, reduce redundant functions, and improve cost-effectiveness.‌
