Honeywell VP527A1067 Pneumatic Valve 3/8" 1.0 CV 2-5 PSI 1/2" Flare

The Honeywell VP527A1067 is a normally-open, single-seated pneumatic valve designed for proportional control of water and glycol solutions in HVAC air conditioning systems. This straight-pattern bronze valve features a built-in pneumatic actuator with a 1/2" OD flare connection for reliable installation and superior performance.

Key Specifications:

• Valve size: 3/8 inch
• Flow coefficient (CV): 1.0
• Spring range: 2-5 PSI
• Connection type: 1/2" OD flare fitting
• Body pattern: Straight-through, two-way
• Construction: Bronze body with stainless steel stem
• Operating medium: Water with maximum 50% glycol solution

Features and Benefits:

• Rolling diaphragm actuator provides long service life and low hysteresis
• Normally-open configuration for fail-safe operation
• Proportional control allows precise modulation of flow
• Bronze construction ensures corrosion resistance and durability
• Compact design enables installation in confined spaces
• Factory-assembled actuator and valve body for immediate installation

The VP527A pneumatic valve series is widely used in unit ventilators, fan coil units, and terminal air conditioning equipment where reliable proportional control is essential. The integrated pneumatic actuator responds to control air pressure signals to modulate valve position and regulate heating or cooling water flow.
