Product catalog summary
Overview: The document provides comprehensive technical specifications and guidelines for the Series 810 Direct Acting Steam Pressure Reducing Valve (PRV). It covers materials, sizing, installation, and operational benefits, ensuring optimal performance in steam systems.
Specifications: The valve is available in materials such as Cast Iron (CI), Cast Bronze (CB), and Stainless Steel (SS), with sizes ranging from 1/2” to 2”. It features metal-to-metal or PTFE composition disc seat types. Spring colors indicate pressure ranges, from 3-15 psig (Black) to 75-140 psig (Blue).
Installation and Operation: Designed to reduce steam pressure from 100-200 psig to 10-140 psig, the Series 810 is suitable for applications like autoclaves and sterilizers. It offers excellent tight shut-off and high capacity with low droop.
Sizing and Selection: A selection guide helps determine the correct specification code based on valve size and spring range. An example demonstrates sizing a regulator for a steam cooker, calculating the required Cv, and selecting the appropriate valve size.
Performance and Advantages: The Series 810 offers low cost, high capacity, and compact design. Built with high-quality materials, it undergoes rigorous testing for long-lasting performance and enhances productivity by optimizing steam flow in batch cooking processes.
Conclusion: The Series 810 Direct Acting Steam PRV is a versatile and efficient solution for steam pressure control, offering various sizes and materials for different industrial applications.
Spring Range and Color Coding: Pressure ranges for different spring colors are crucial for selecting the appropriate valve, with Black (3-15 psig), Silver (10-30 psig), and Blue (75-140 psig) options.
Sizing Procedure: A step-by-step example for sizing a PRV for a steam cooker is provided, demonstrating the calculation of the required Cv value for subcritical and critical flow conditions.
Performance Comparison: The document illustrates the impact of proper valve selection on productivity, showing how a correctly sized valve can reduce batch cooking time by increasing steam flow capacity.
Installation Guidelines: An installation diagram shows the placement of the Series 810 PRV with other components like stop valves and steam traps for efficient operation.
Selection Guide: A coding system specifies the exact valve configuration based on size, material, spring range, and seat type, with an example code for a 3/4” regulator.
Additional Information: Other Series 800 regulators are mentioned, highlighting features like high capacity and accuracy, suitable for sterilizer applications.
