Regulating Valves
Regulating valves provide accurate, automated control of key process parameters such as flow rate and pressure and, depending on the model and application, temperature and tank level. They help maintain stable operation, consistent quality, and efficient performance in hygienic liquid-processing lines.
Overview
Regulating valves continuously adjust valve position based on a control signal to maintain the target process value. They are commonly used for stable flow/pressure control and for control duties beyond flow (depending on the platform).
What regulating valves do
- Maintain the target flow rate even when upstream/downstream conditions change.
- Support stable pressure control to protect equipment and process consistency.
- Depending on model: enable control of temperature and tank level.
- Enable automation via actuators/positioners and integration into PLC/control systems.
Typical applications
- Hygienic processing in dairy, beverage, food, brewery, pharma and biotech
- Flow/pressure control in product lines, CIP circuits and utility sections
- Process stabilization for quality, repeatability and energy efficiency
- Control loops requiring automated response and reliable hygienic design

FAQ
Quick answers to common regulating valve questions.
What is a regulating valve?
A regulating valve is a control valve that adjusts its position to maintain a target process value (e.g., flow or pressure) based on a control signal.
How do I choose between RV-ST and RV-P?
Choose based on your control duty, automation preference, and operating range (Kv selection). RV-P is typically selected when electro-pneumatic actuation and broader control duties are required; RV-ST is a robust single-seat regulating platform for flow/pressure control.
What data do you need to size a regulating valve?
Flow range, upstream/downstream pressures (or ΔP range), media, temperature range, connection standard, and the control duty (flow/pressure/etc.).
