VG7241PT+822D00 Johnson Controls Valve / Actuator

Overview

The Johnson Controls VG7241PT+822D00 is a 2-way, normally open pneumatic globe valve and actuator assembly designed to regulate the flow of water and steam in commercial HVAC systems. It features a rugged cast bronze body, a 1-1/4 inch NPT connection, and a spring-return pneumatic actuator engineered for precise modulation and long-term service in demanding hydronic setups.

Features

• Two-way normally open configuration for reliable fail-safe performance.
• Equal percentage flow characteristic provides superior control stability by matching valve output to heat exchanger requirements.
• Heavy-duty cast bronze body built to meet robust industry pressure and temperature standards.
• High-quality brass trim and specialized packings for enhanced seal integrity and simplified field maintenance.
• Powered by a spring-return pneumatic actuator with a 4-8 psi spring range for positive shutoff.
