Description
Overview
The Honeywell VP531C1018 is a 3/4″ NPT two-way pneumatic terminal unit valve engineered for precise proportional control in commercial HVAC hydronic and steam systems. Designed for use with both water and steam applications, this normally open valve delivers reliable, responsive flow regulation in terminal unit installations such as fan coil units and unit ventilators.
Key Features
- 3/4″ NPT two-way valve body for straightforward inline installation
- 2.6 Cv flow coefficient for accurate flow capacity sizing
- 2–5 PSI standard spring range for proportional normally open valve action
- Push-on air connections compatible with 1/4″ O.D. plastic pneumatic tubing for easy field hookup
- Suitable for use with hot water, chilled water, or steam systems
- Includes an additional 3–10 PSI spring, providing installation flexibility for a wider control range
- Proportional control action for smooth, modulating flow response
Application
The VP531C1018 is ideal for terminal unit applications in commercial buildings where pneumatic control systems are in use. Its normally open design ensures flow is maintained in the absence of control air pressure, making it well-suited for heating coil service. The included 3–10 PSI spring expands the valve’s versatility, allowing field technicians to reconfigure the control range to match system requirements.
