P545NCB-25C Johnson Controls Lube Oil Control

Overview

The Johnson Controls VG7241ST+823C00 is a pneumatic valve and actuator assembly designed to regulate the flow of hot water, chilled water, or saturated steam in HVAC systems. It combines a 2-way, normally open cast bronze globe valve with an MP82 spring return pneumatic actuator, providing reliable control and failsafe operation.

Features

• Industrial-grade drawn-steel actuator with an electro-painted finish for corrosion resistance
• Over one million cycles tested for longevity and reliable operation
• In-place valve repacking simplifies maintenance and serviceability
• Spring return action ensures a normally open position upon loss of pneumatic pressure
• Cast bronze body with brass trim provides durable performance

Specifications

• Valve Size: 2 inches (FNPT connection)
• Flow Coefficient (Cv): 46.2 with an equal percentage flow characteristic
• Nominal Spring Range: 3 to 7 psig (actuator diaphragm area of 25 sq. in.)
• Maximum Supply Air Pressure: 25 psig (172 kPa)
• Static Pressure Rating: ANSI Class 250 (up to 400 psi maximum allowable pressure)
• Media Temperature Range: Water from 35 to 284°F (2 to 140°C); saturated steam up to 38 psig

Applications

• Designed for regulating fluid flow in commercial and industrial HVAC building automation systems
• Controls hot water or chilled water distribution networks
• Suitable for low-pressure steam applications up to 38 psig saturated steam lines
• Ideal for environment monitoring and precise climate zoning systems requiring equal percentage control dynamics
