HTS KS – Butterfly Valves BVG, BVA, BVH Series

Overview

The Honeywell BVG, BVA, and BVH Series are butterfly valves designed for continuous control of gas, air, and hot air or flue gas flow rates in industrial combustion and thermal processing systems. Prepared for direct attachment of an IC 20 or IC 40 actuator and for fitting between two flanges, these valves deliver control ratios up to 10:1 across a wide range of process conditions.

The BVG and BVA variants handle gas and cold air applications up to 500 mbar inlet pressure, while the BVH and BVHS are engineered for elevated-temperature service up to +450°C at up to 150 mbar. Available in sizes DN 40 to DN 150, the series covers a broad range of burner and process flow control applications.

Features & Benefits

• BVA / BVAF – Continuous control of air flow; BVAF operates clearance-free for immediate response to control commands
• BVG / BVGF – Continuous control of gas flow; BVGF variant is clearance-free for delay-free actuation
• BVH / BVHS – Continuous or staged control of hot air or flue gas up to +450°C; TWINDISC valve disc with stop bar ensures very low leakage rates
• Actuator-ready design – Prepared for direct attachment of IC 20 or IC 40 actuators without additional adapters
• Flange-to-flange installation – Fits directly between standard EN or ANSI flanges for straightforward installation
• Manual adjustment option – BVG and BVA models available with manual adjustment (BVG..H)
• Wide size range – DN 40 to DN 150 (BVG, BVA) and DN 40 to DN 100 (BVH) to match system flow requirements
• Stainless steel drive shaft – Provides corrosion resistance and long service life across all variants
