Hydraulic Flow Control Valves - X52E Orifice Plate Assembly | Cla-Val

Cla-Val X52E – Orifice Plate Assembly

The Cla-Val X52E is an orifice plate assembly designed for use with Cla-Val hydraulic flow control valves. It does not independently regulate flow; instead, it generates a predictable pressure drop, providing a stable differential signal to the main valve’s pilot circuit for accurate flow control.

Functional Role

Installed downstream of the control valve, the orifice plate creates a differential pressure proportional to flow rate. This differential is used by the pilot circuit to modulate the main valve position, enabling precise throttling or opening based on process requirements.

Construction / Installation

• Wafer-type holder for installation between flanges (EN, ANSI, or JIS).
• Compact design, no separate valve body.
• Chamfered inlet side ensures correct orientation during installation.
• Sensing port should be positioned laterally to minimize air entrapment or signal line blockage.

Application Limitations

Do not install immediately adjacent to butterfly valves, as disc movement may interfere with the orifice plate assembly.

Typical Applications

• Cla-Val rate-of-flow control valves
• Potable water distribution networks
• Tank filling lines
• Pressure filter systems
• Industrial process water circuits

Selection Criteria

Selection requires pipe diameter, target flow rate, orifice bore, operating pressure, flange standard, and compatibility with main valve pilot tubing. Suitable for water and compatible liquids; consult datasheet for pressure class, temperature range, and material options.
