Series 1600 Univers

Product catalog summary
Overview: This document outlines the technical specifications and safety instructions for fittings used in gases, cryogenic, and high-pressure engineering, applicable to industries such as aerospace, marine, and energy. It is produced by STÖHR Armaturen GmbH & Co KG.
Safety Instructions: The responsibility for selecting and installing valves lies with the system designer and user. Important factors include valve function, sealing type, material compatibility, operating pressure, temperature, and system environment.
Specifications:
  • Temperature Ranges: Cryogenic (-271°C to -30°C) and ambient (-30°C to +50°C).
  • Pressure Ranges: Low (<1 bar), Medium (up to 40/45 bar), High (up to 360 bar), Ultra-High (up to 800 bar).
  • Valve Functions: Includes Globe Valve (GV), Control Valve (CV), Check Valve (CHK), Strainer (STR), Overflow Valve (OV), and Relief Valve (RV).
  • Actuation Types: Manual, pneumatic, electric, solenoid, and spring-based.
  • Vacuum Jacketing: Options for non-suitable, standard, and optional vacuum-jacketed pipes.
Technical Data:
  • Service Fluids: N2, O2, Ar, H2, He, NG.
  • Operating Temperatures: Fluid (-271°C to +50°C), Environment (-30°C to +50°C).
  • Body Material: Stainless steel with various sealing options and leakage rates.
  • Installation: Horizontal flow direction with actuator on top, max 30° vertical.
Valve Series Univers 1600: Designed for cryogenic temperatures down to LHe (1.8 K), featuring optimized heat input, flow rate, and options for thermal coupling and surface treatment to reduce blistering.
Dimensional Data: Detailed measurements for various valve sizes, including length, height, and Kv values, with both imperial and metric dimensions available.
Technical Specifications: Pneumatic cryogenic control valves are designed for extreme conditions, handling service fluids like N2, O2, Ar, H2, He, and natural gas. They operate at temperatures from -271°C to +50°C and are made from stainless steel with various seat sealing options. The valves feature a diaphragm actuator, are available in angle body shape, and have a safety position of normally closed or open. They are equipped with a position indication scale and require an actuating pressure of 6 ± 0.5 bar.
Design and Features: The valve body is optimized for minimal heat input and precise flow control with regulation ratios of 1:30/50/100. Optional features include a thermal coupling and electro-polished surfaces for improved media flow. The valves are suitable for installation in vacuum-insulated tubes and can be customized for specific applications.
Installation and Operation: Valves are installed horizontally with the actuator on top, allowing a maximum tilt of 30°. They come with standard welding flanges and can be adapted for larger sizes or alternative pressure levels upon request. The valves are designed for easy integration with various transmission protocols and include features like limit switches and air filters.
Additional Options: Optional features include a convection brake for thermal separation, sliding thermal contact, and customer-specific regulation cones for low-pressure applications. The valves can be equipped with a high-value electronic position controller and memory function.
Checklist for Specification: When requesting a quote, customers should specify valve type, actuation method, body type, nominal diameter and pressure, medium type and temperature, and any additional options or requirements. The checklist ensures all necessary specifications are communicated for accurate product selection.
