Product catalog summary

Overview

This document from STÖHR ARMATUREN GmbH & Co KG provides detailed technical information and specifications for fittings and valves designed for gases under cryogenic and high-pressure conditions, primarily targeting aerospace, marine, and energy industries.

Safety Instructions and Responsibility

The document emphasizes the importance of safety and proper valve selection. While the company provides catalogs, checklists, and sales support, the responsibility for choosing the correct valve type, installation, commissioning, operation, and maintenance lies with the system designer and user. Key factors to consider include valve function, sealing type, material compatibility, operating pressure and temperature, and system environment.

Legend and Specification Icons

The document uses a set of icons and abbreviations to classify valves by media temperature, pressure range, function, actuation type, and suitability for vacuum-jacketed pipes:

Media Temperature: Cryogenic (-271°C to -30°C), Ambient (-30°C to +50°C)
Pressure Range: Low (<1 bar), Medium (up to 40/45 bar), High (up to 360 bar), Ultra-High (up to 800 bar)
Valve Functions: Globe Valve, Control Valve, Check Valve, Strainer, Overflow Valve, Relief Valve
Actuation Types: Manual, Pneumatic (with or without position regulator), Electric, Solenoid, Spring-based
Vacuum Jacketing: Not suitable, Standard suitable, Optional with vacuum flange

Product Descriptions and Technical Data

Blasts 2600 Pressure Relief Valves

Two variants of spring-loaded pressure relief valves designed to vent unwanted gas accumulations from vacuum systems:

Version 1: Response pressure 20 to 1250 mbar, valve body machined from solid stainless steel, soft seat sealing with Viton, suitable for fixed or mobile gas line connections, installation preferably vertical flow direction, leakage rate 1x10^-3 mbar*l/s.
Version 2: Response pressure 20 to 1000 mbar, valve body made from stainless steel or aluminum alloy, seat sealing with PCTFE/Viton, similar installation and leakage characteristics as version 1.

Axial Overflow Check Valve (Blasts 2600)

Spring-loaded axial check valve with a polyimide plastic ball for high response pressure and fast closing. Designed for non-vacuum insulated pipes with welded or sealed housing halves. Suitable for gases like N2, O2, Ar, H2, He. Operating temperature range from -196°C to +60°C. Leakage rate 1x10^-3 mbar*l/s.

Dimensional Data and Ordering Information

The document provides detailed dimensional tables for valve connections, lengths, and outflow cross-sections for different nominal diameters (DN) and connection types (e.g., KF). Part numbers are listed for stainless steel and aluminum versions where applicable.

Valve Specification Checklist

A comprehensive checklist is included to assist customers in specifying valves accurately. It covers:

Valve type, quantity, and sizes
Actuation type and power supply details
Valve functions (on-off, control, check, overflow check, strainer)
Body form (straight or angle)
Nominal pressure and cracking pressure for check valves
Medium type and temperature
Connection types and standards
Additional options such as welding flanges for vacuum jacketing, surface treatments, purge connections, thermal coupling, and customer-specific acceptance tests
Installation environment and special conditions (e.g., desert, saltwater)
Fail-safe positions and ATEX compliance

Critical Parameters and Recommendations

Exact response pressure must be specified when ordering pressure relief valves.
Installation position is generally flexible but recommendations are given (e.g., vertical or horizontal flow direction).
Material selection must consider the nature of the media, especially for dangerous, toxic, or corrosive gases.
Leakage rates are tightly controlled to 1x10^-3 mbar*l/s to ensure system integrity.
Vacuum jacketing suitability is clearly indicated for each valve type.
Users must ensure compatibility of valve sealing materials with operating temperatures and media.

Contact and Support

STÖHR ARMATUREN GmbH & Co KG provides contact details for sales and technical support. Customers are encouraged to use the checklist for RFQ submissions to ensure precise valve specifications and to consult safety instructions carefully.
