HONEYWELL VRW2JW4SMD Flanged Pressure Independent Control Valve

Product Description

The Honeywell VRW2JW4SMD is a flanged pressure independent control valve designed for pressure-regulated control in hydronic systems. This valve helps maintain temperature stability while automatically adjusting flow during pressure changes. It features an integrated pressure control cartridge that enhances flow balancing and control.

• Includes a differential pressure regulator for stable pressure drop across the valve seat.
• Provides equal percentage flow characteristic with a non-rising plug.
• Two test ports for ease of venting and pressure gauge connections.

Product Highlights

This valve is suitable for hot or chilled water and glycol solutions up to 50% concentration, enhancing system efficiency and reliability.
