Advantages of Sliding Gate Control Valves

Schubert & Salzer's sliding gate control valves are designed as an effective alternative to traditional control valves. The sliding gate valve controls liquid, vapor, and gaseous media precisely, quickly, and economically. The design is uniquely simple, but is intelligently built to handle complex applications that require precise control under taxing conditions. They are an excellent choice for a variety of media, including steam, liquids, and gases. 

How Sliding Gate Control Valves Work

A sealing plate with many crossways slots of equal height is fixed in the body at right angles to the flow direction. A moving disc with the same slot arrangement moves in parallel to the fixed disc, thereby changing the flow cross-section. The prevailing differential pressure presses the moving disc against the fixed disc and seals it. 

The machined orifices in the fixed plate or disc can vary in design, size, and configuration, determining the flow coefficient (Cv) and the flow characteristic of the valve. As the cross sectional area changes and the valve modulates, flow is broken apart, creating a variable field of area flow, which reduces energy and noise. The differential pressure creates a unique seal between the two plates, and when in the sealed position, an overlap of approximately 1 mm creates a leak-tight valve.


  1. Fits into tight spaces
  2. Outstanding rangeability
  3. 40:1 to 160:1
  4. Easy to install and maintain
  5. Variable Cv Values
  6. Significantly reduced energy consumption
  7. Minimal wear
  8. Extremely low leakage rate
  9. Optimal flow control
  10. Maximum differential pressures

Field Instrumentation Selection and Total Cost of Ownership

Within a plant, field instrumentation and actuators are the sensors of the process and the point at which the process automation system detects, measures, and responds to process conditions, including pressure, temperature, flow, and level. Process manufacturing plants of any size and complexity typically need thousands of field instruments, valves, actuators, and other devices. While critical to plant operations, field instrumentation is often purchased ad-hoc and based on the lowest initial cost. This paper describes the importance of considering the total cost of ownership across their lifecycle, from initial purchase through their useful life.

Yokogawa, a world leading manufacturer of field instruments and process control equipment, offers this comprehensive white paper on understanding the relationship between your field instrumentation and the hidden costs of ongoing maintenance.
