Segmented disc valves

Robust, durable and highly precise in expanded line sizes

Segmented disc valves icon Segmented disc valves by Schubert & Salzer

Segmented disc valves by Schubert & Salzer offer high precision over a wide flow range. Due to the robust design and the bi-directional flow capability, segmented disc valves are suitable for fluids as well as steam and other gases. The valve also is not affected by contaminated media. Range of applications varies amongst a large degree of process industries and utilities.  Availability in sizes through 32 inch.

Segmented disc valves

Functional principle of segmented disc valves

Segment disc valves incorporate a very simple yet effective design.

The central throttling element - a pair of segment discs that glide and seal against each other - are positioned in the valve body perpendicular to the flow direction. A fixed segment disc determines the Cv and flow characteristic. The fixed disc is engaged by a moving disc having the same geometry. Driven in a linear motion by a serrated actuator stem that sequentially increases or decreases the cross sectional area of the two segmented discs, these seating elements provide high rangeability with precise control.

The moving disc is spring loaded and this constant force allows bi-directional flow. The valve can also be installed in any direction and low differential pressures are nonproblematic.

This special design makes segment disc valves unique inasmuch as they combine precision control in extreme operating conditions with tight sealing and very low exposure to wear.

The advantages of segmented disc valve

Low actuation forces, compact design, low weight

Long service life, minimal wear, low operating costs

Robust design, high resistance to slightly contaminated media

Bi-directional flow

Precise control

High KVS values

Low noise emission and non-sensitive to cavitation

High degree of tightness, low leakage due to the functional principle

Reduced energy consumption and low insulation loss
