P70MA-1C Johnson Controls Pressure Control

Overview

The Johnson Controls VG12A5JV+94NGGA is a 4-inch, 2-way flanged ball valve assembly factory-mounted with an M9220-GGA-3 spring return electric actuator. It is designed to regulate the flow of hot water, chilled water, and 50/50 glycol solutions in commercial Heating, Ventilating, and Air Conditioning (HVAC) systems. This assembly features a spring-closed fail-safe position and supports proportional control.

Features

• High closeoff pressure rating of 100 psi providing tight shutoff
• 300 Series stainless steel ball and stem assembly for long-term durability
• 500:1 rangeability ensuring precise environmental control under all load conditions
• Double O-ring stem seal offering leak-free operation for over 200,000 cycles
• Maintenance-free design with graphite-reinforced PTFE seats backed by EPDM O-rings

Specifications

• Valve Size: 4 inches (DN100)
• Body Configuration: 2-way
• Flow Coefficient: 176 Cv
• Flange Type: ASME Class 150
• Actuator Type: M9220-GGA-3 Spring Return (Spring Closes)
• Control Signal: Proportional DC 0(2) to 10 V or 0(4) to 20 mA
