P70KA-7C Johnson Controls Pressure Control

Overview

The Johnson Controls VG7443LT is a 2-way, normally closed (NC) globe valve designed for precise flow control of hot water, chilled water, and low-pressure steam in commercial and light industrial HVAC hydronic systems. It features a push-down-to-open (PDO) action and is engineered for durability and corrosion resistance.

Features

• 2-way, normally closed configuration for fail-safe operation in the event of power loss.
• Equal percentage flow characteristic provides smooth, responsive modulation and stable control.
• Cast bronze body offers superior corrosion resistance and a long service life.
• Stainless steel trim ensures enhanced durability and reliable seating.
• Standard threaded stem design provides compatibility with a wide range of Johnson Controls electric or pneumatic actuators.
• Secure, leak-resistant connection via standard female NPT end connections.
