U12/22/42/ST2000

Product catalog summary

Overview: This document provides technical specifications and features of dome-loaded pressure regulators U12, U22, and U42, designed for industrial gas applications. These regulators are manufactured by Spectron Gas Control Systems GmbH and are suitable for remote-controlled pressure regulation in various industrial processes.

Product Features:

Dome Loaded Diaphragm Line Pressure Regulators: These regulators are designed for high control accuracy and are suitable for flow rates ranging from 300 m³/h to 2,000 m³/h.
Remote Control Capability: They can be remotely controlled, making them ideal for process control and cutting machines.
Integrated Relief Valve: Each regulator includes a relief valve for safety and pressure management.
Central Filter: A central filter is integrated to ensure clean operation.
Oxygen Approval: The regulators are approved for use with oxygen, expanding their application range.

Technical Specifications:

U12 Regulator: Maximum flow rate of 300 m³/h, inlet pressure up to 40 bar, and outlet pressure up to 30 bar. Constructed with a brass body and NBR diaphragm.
U22 Regulator: Maximum flow rate of 600 m³/h, similar pressure specifications as U12, but with a heavier weight of approximately 6.8 kg.
U42 Regulator: Supports the highest flow rate of 2,000 m³/h, with a brass body and EPDM diaphragm, weighing approximately 14 kg.

Performance Factors: The document outlines performance factors such as pressure drop percentages (L5, L10, Lmax) and their impact on outlet pressure variations, which are crucial for evaluating the flow rates and efficiency of each regulator model.

Ordering Information: Each regulator model has specific part numbers for different inlet and outlet configurations, facilitating easy ordering and installation.

Pilot Pressure Regulator ST 2000: This regulator is used to control the dome-loaded pressure regulators and features high control accuracy, a central filter, and is designed for panel mounting. It is also approved for use with oxygen.

Conclusion: The document provides comprehensive details on the specifications, features, and ordering information for Spectron's dome-loaded pressure regulators, highlighting their suitability for industrial applications requiring precise pressure control.
