VG7243ET Johnson Controls Valve

Overview

The Johnson Controls VG7243ET is a high-performance, 1/2-inch 2-way normally open globe valve engineered for precise modulating or proportional fluid control in commercial HVACR and hydronic systems. Featuring a heavy-duty cast bronze body with stainless steel trim, this push-down-to-close valve provides exceptional durability and corrosion resistance in hot water, chilled water, or saturated steam installations.

Features

• Two-way normally open (N.O.) configuration
• Push-down-to-close (PDC) actuator action
• Equal percentage flow characteristic for stable, accurate modulating control
• Premium stainless steel trim and cast bronze body for extended service life
• Long-life spring-loaded PTFE and elastomer V-ring packing ensuring tight shutoff
• Seamless direct-coupled compatibility with VG7000 and M9000 series actuators without requiring additional linkages
