Honeywell VP531C1067 Pneumatic Radiator Valve 1/2" Straight Normally Open 2-5 PSI

The Honeywell VP531C1067 is a pneumatic radiator valve designed for precise control of hot water or steam heating systems. This normally open (N.O.) valve features a 1/2-inch straight connection configuration, making it suitable for space-constrained installations where inline mounting is required.

Key Specifications:

• Valve coefficient (Cv): 2.3 for accurate flow control
• Operating pressure range: 2-5 PSI pneumatic signal
• Normally open configuration - closes upon air pressure application
• 1/2-inch NPT straight body design
• Direct replacement for VP531A1020 model

This valve is commonly used in commercial HVAC systems, zone control applications, and radiator temperature regulation. The pneumatic actuation provides reliable, fail-safe operation in heating distribution systems. When pneumatic pressure is applied within the 2-5 PSI range, the valve modulates to control water flow, allowing precise temperature management in individual zones or radiators.

Application: Ideal for retrofitting older pneumatic control systems or new installations requiring pneumatic valve control in hydronic heating applications.
