V-3966-1002 Johnson Controls Reconditioning Kit

Overview

The Johnson Controls V-3966-1002 is a 1/2-inch flare-connection, two-way pneumatic valve designed for precise fluid flow control in commercial and industrial HVAC systems. Housed in a durable bronze body, this valve operates in a normally closed configuration, providing a reliable fail-safe that automatically closes the valve upon a loss of pneumatic signal to protect system integrity.

Features

• Designed with a high-quality bronze body to ensure long service life in demanding environments
• Features a secure 1/2-inch flare connection that simplifies field installation and creates a leak-resistant seal
• Utilizes a normally closed fail-safe design to shut off flow automatically if pneumatic pressure drops
• Integrates a push-down-to-open mechanism for efficient, pressure-responsive operations
