Honeywell VRN2H5SX4000 Pressure Independent Control Valve and Actuator Assembly

Product Description

The Honeywell VRN2H5SX4000 is a pressure independent control valve assembly suitable for HVAC systems. This assembly keeps a constant flow of hot or chilled water with up to 50% glycol solutions in closed-loop systems, regardless of pressure changes. It integrates flow and temperature control, managing flow in hydronic circuits to maintain desired temperatures.

This product has a differential pressure regulator, which removes the need for system balancing. This enables chillers to operate efficiently. The valve consists of a three-inch NPT two-way valve with a capacity of seventy gallons per minute (GPM) and includes a floating two-position non-spring return actuator that operates at twenty-four volts alternating current (VAC).

• Maintains constant flow in HVAC systems with fluctuating pressures.
• Features a three-inch NPT, two-way valve with seventy GPM capacity.
• Includes a floating, two-position, non-spring return twenty-four VAC actuator.

Product Highlights

This pressure independent valve assembly is essential for regulating fluids in HVAC setups and ensuring operational efficiency.
