HTS KS – RV / RVS Control Valves

Overview

The Honeywell RV and RVS are modulating control valves designed for continuously regulated burner processes involving gas and air. The RV is a standalone control valve, while the RVS integrates a safety shut-off solenoid valve in a single compact unit. Both models deliver a linear ratio of input signal to flow rate with a wide control ratio of up to 100:1, making them well suited for precise combustion ratio control across a broad range of industrial applications.

Available in multiple sizes with threaded or flanged connections, the RV and RVS accept three-point step control or continuous control inputs (0–10 V or 4–20 mA) and provide position feedback via potentiometer or 4–20 mA output. Enclosure rating IP54 and ambient temperature range of -20 to +60 °C support demanding industrial environments. The series is CE and UKCA certified and carries AGA approval for select RVS..ML configurations.

Features & Benefits

• Linear ratio of input signal to flow rate — ensures predictable, repeatable combustion control across the full operating range
• Control ratio up to 100:1 — supports wide turndown without sacrificing accuracy
• RVS variant integrates a safety shut-off solenoid valve — reduces installation space, piping, and component count
• Accepts three-point step control or continuous control (0–10 V or 4–20 mA) — compatible with a broad range of combustion management systems
• Position feedback via potentiometer or 4–20 mA signal — enables precise closed-loop control integration
• Suitable for gas and air — a single valve family covers both fuel and combustion air control
• Adjustable running time (30 or 60 seconds) — allows tuning to match burner and process requirements
• Aluminum alloy (AlSi) housing — lightweight and corrosion-resistant construction
• IP54 enclosure rating (IEC 529) — protects against dust and water ingress in industrial environments
• CE and UKCA certified; AGA approved (RVS..ML models) — meets major international compliance requirements
