Schubert & Salzer Sliding Gate Control Valves from Miller Energy

The sliding gate control valve from Schubert & Salzer has an innovative design that allows it to handle complicated applications requiring precise control under challenging circumstances. The sliding gate valve's actuation power is roughly 10% that of a globe valve of the same nominal size and differential pressure, even if both designs have almost the same flow rate.

The valve handles steam, liquids, and gases. Sliding gate valves outperform traditional control valves and use smaller actuators because they require reduced actuating force. They provide lower weight and reduced installation dimensions due to the space-saving wafer design, especially in nominal sizes mid-large. 

Due to the unique design, harmful cavitation zones occur 1 - 2 meters beyond the valve in the case of a sliding gate valve, placing the destructive cavitation bubbles downstream, in the pipeline's center, causing no damage.

Sliding Gate Control Valves from Schubert & Salzer

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.

Sliding Gate Control Valve Operation

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.
