The Honeywell VRN2F1SXB202 is a 2-way pressure regulated control valve assembly designed to control flow and temperature in hydronic systems. This valve automatically adjusts the flow, responding to pressure changes to maintain desired temperature levels. It includes an integrated pressure control cartridge that ensures balanced flow. The product is compatible with both water and glycol solutions, offering flexibility for various system types.
Features female NPT connections.
Accommodates hot or chilled water with up to 50% glycol solutions.
Incorporates differential pressure regulator for stable pressure management.
Product Highlights
The valve's forged brass body and stainless steel trim provide durability and reliability, while its design allows for easy integration with standard Honeywell actuators.
