Critical Ethylene Level and Flow Application Brochure

Critical Ethylene Level and Flow Applications

In ethylene plants, balancing environment, health, and safety is essential while maximizing productivity.

Level and flow instrumentation will assist in preventing loss of primary containment and maintaining a safe environment inside of the tank. That’s critical, because incident consequences are significant, with the direct cost of a work-related death of $1M and indirect costs approximately 4 times greater. In addition, there is the lasting damage to your brand reputation and the compromised safety of the local community. Instrumentation can also assist in maximizing productivity, including interface type measurement in some of the harshest environments.

This brochure contains a wide spectrum of Magnetrol® and Orion Instruments® level and flow products that conform to the latest safety standards, including SIL requirements, to assist in the most critical applications in ethylene plants.

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.

ADVANTAGES OF THE SLIDING GATE CONTROL VALVE
