The Honeywell VRN2DPPX4000 is a pressure independent control valve that integrates an electric actuator. This valve has a one and one-quarter inch NPT connection and supports a flow rate of twenty gallons per minute. It features a plated brass trim and a DCA profile, allowing for effective floating on/off control with fail-in-place capabilities. This valve is perfect for managing hot or chilled water systems that may contain up to fifty percent glycol solutions. It operates on twenty-four volts AC.
Features a one and one-quarter inch NPT connection.
Provides a two-way valve setup with a flow rate of twenty gallons per minute.
Designed for floating on/off control with fail-in-place functionality.
