Pressure Regulator

Product catalog summary

Overview: The document provides technical specifications and operational guidelines for Emerson Climate Technologies products, focusing on solenoid valves, temperature and pressure controls, and pressure regulators for industrial refrigeration and HVAC systems.

Pressure Regulators:

ESR (Electronic Stepper Regulator): Features a bi-polar stepper motor for precise temperature control, suitable for supermarket display cases and refrigerated transport. Specifications include a maximum working pressure of 500 psi and operating temperatures from -40°F to +280°F.
IPR (Inlet Pressure Upstream Regulator): Maintains minimum evaporator inlet pressure with a compact design and solid copper connections, adjustable from 0-225 psig.
EPRB(S) (Brass Body Upstream Regulator): An energy-efficient, pilot-operated regulator with a wide adjustment range and suction stop feature for enhanced serviceability.
OPR (Outlet Pressure Downstream Regulator): Prevents compressor motor overload by maintaining maximum outlet pressure, with adjustable ranges from 0-230 psig.

Features and Options:

Regulators are designed for easy installation and serviceability, with vertical or horizontal installation options.
Products are corrosion-resistant and compatible with refrigerants like R-134a, R-22, and R-404A.
Includes specific ordering information and part numbers for easy procurement.

Diagnostic Tools:

MTB-1: A handheld diagnostic tool for stepper valve applications, featuring an easy-to-use interface.

Dimensional Data: Provides detailed dimensional data for each product to ensure proper fit and installation.

Refrigerant Performance: The document includes performance data for refrigerants such as R-502, R-407C, R-134a, R-22, R-404A/R-507, and R-12, detailing evaporator temperatures, pressure drops, and capacities.

Key Sections:

Refrigerant Performance Tables: Extensive tables show refrigerant performance at various evaporator temperatures and pressure drops.
Evaporator Temperature and Pressure Drop: Data on how these factors affect capacity, crucial for refrigerant selection.
Extended Capacity Tables: Show capacity changes with varying pressure drops and evaporator temperatures.
Valve Set Points and Adjustments: Information on valve set points and adjustments for optimal performance.

Critical Information:

Refrigerant Types: Covers multiple refrigerants with unique properties and performance metrics.
Pressure Drop Impact: Understanding its impact on capacity is vital for system design.
Temperature Ranges: Tables cover a wide range of temperatures for flexible application and design.

Conclusion: This document is a comprehensive guide for engineers and technicians, providing essential data for selecting and optimizing refrigerant use based on specific system requirements.
