High pressure valves

Product catalog summary
Specifications:
The document outlines the specifications for high-pressure valves manufactured by Stahl-Armaturen PERSTA GmbH. These valves adhere to DIN, EN standards, the European Pressure Vessel Guideline 97/23/EG, and ASME B16.34 Code. They are suitable for non-corrosive and non-abrasive liquid or gaseous media under normal conditions. The valves are available in pressure classes ranging from 900 to 4500 and can withstand temperatures up to 1200°F (650°C). Detailed tables provide specific pressure ratings for different temperature ranges.
Design and Materials:
The valves feature a die-forged body and bonnet, with components like the stem and disc made from corrosion-resistant Cr-steel. The body seat is tapered and welded with stellite for enhanced durability. Materials used include A 105, A 182 F1, F12, F22, F91, and F92, suitable for high-temperature steam, water, and various industrial applications.
Applications:
These valves are used in high-temperature steam and water systems, refining processes, petrochemical and chemical industries, and power plants.
Design Highlights:
The valves are designed for easy maintenance, featuring a separate body and bonnet, non-turning rising stem, and a position indicator. The design minimizes potential leakage points and allows for the addition of an actuator flange.
Recommendations:
Customers are advised to specify any deviations from normal operating conditions in their orders to allow for appropriate design adjustments. Measures such as special material selection, increased wall thickness, and additional equipment for overpressure protection can be implemented.
Installation and Safety:
The document recommends installing vibration dampers and ensuring safe drainage of dangerous media in case of leakage. The valves are CE-marked, indicating compliance with the European Pressure Equipment Directive 97/23/EG.
Additional Information:
Further details on operation and warnings are available in the operation instruction BA 10S.002GB. The document also includes a table of contents for various valve types and their specifications.
Technical Specifications and Standards:
The document provides detailed specifications for various pipe sizes and wall thicknesses, measured in both inches and millimeters. It includes data for different pipe schedules and wall thickness categories, such as XXS (Double extra strong wall thickness). The specifications conform to ASME standards, specifically ASME B16.25 for buttwelding ends and ASME B16.11 for socket welding ends.
Procedures and Recommendations:
When ordering buttwelding end valves, it is crucial to specify the type of weld preparation desired and the pipe schedule to be used. Missing or incomplete information may delay shipment. The document emphasizes the importance of finish machining and inspection of welding ends, especially where thickness is less than 1.15t.
Approvals and Certifications:
The document lists various approvals and certifications from international bodies, including DIN EN ISO 9001:2000, CE 0045, and CSA B51. It also mentions specific testing firms and auditing companies like FRAMATOME/Siemens/AREVA and TÜV Cert.
Material and Connection Codes:
It provides a coding system for materials and connections, with specific PERSTA codes for different ASTM materials and connection types, such as flanges, butt welded ends, and socket welded ends.
Valve Types:
The document categorizes high-pressure valves, including globe valves, gate valves, swing check valves, and line blind valves, each with specific PERSTA codes.
Contact Information:
The document concludes with contact details for Stahl-Armaturen PERSTA GmbH, including their address in Germany, phone number, fax, and email.
