Description
The Johnson Controls VP140HDA+778GGA is a Pressure Independent Control Valve (PICV) that combines a control valve, differential pressure regulator, and flow limiter into a single compact assembly. Designed for hydronic heating and cooling systems, this 1/2″ valve delivers precise flow control regardless of system pressure fluctuations, eliminating the need for separate balancing valves and simplifying commissioning.
Key Features
- Pressure Independent Control Valve (PICV) — integrates flow limiting, differential pressure regulation, and modulating control in one unit
- 1/2″ pipe connection for easy installation in standard hydronic piping
- Maximum flow rate of 1.98 GPM, factory pre-set for accurate system balancing
- 24V actuator voltage for compatibility with standard building automation and HVAC control systems
- NSR (Normally Spring Return) actuator provides fail-safe operation — valve returns to a defined position on power loss for system protection
- Eliminates the need for separate differential pressure control valves and manual balancing valves
- Simplifies hydronic system commissioning and reduces installation time
- Ideal for variable flow hydronic systems in commercial HVAC applications
