Valves in different types and series Series Sticks Elips Univers Balans Axius
All STÖHR valves are provided with stainless steel bellows. This means maximum tightness in connection with high capacity, long life and the lowest leak rates.
Stöhr products are charcterised by:
Customer oriented solutions
Valve AXIUS The compact axial valve
The arrangemant of the actuator on the axle offers essential technical advantage. The tube inside the valve can be shifted axially. The tube is sealed by a metal seal to the atmosphere. Tube and valve actuator are the only flexible components inside the valve. The pneumatic actuator is also sealed by a metal seal.
Valve BALANS The technically challenging high pressure valve with low actuating force
With the innovative technique of STÖHR ARMATUREN a settled balance of power is created for a pressure to 420 bar. Only low actuating forces are necessary for actuating the valve. The sealing to atmosphere by a stainless steel bellow guarantees the lowest leak rates. BALANS valves are suitable for temperatures to 223 K (-50°C).
Spring-loaded pressure relief valve with low response pressure between 100 – 1000 mbar. For the relief of unwanted gas-buildup from vacuum systems. Connections of a flexible or unflexible tube to collect the gas are possible. The valve body is machined from one piece of solid stainless steel.
Valve BLOCKS Valves for modular design and individual mixing
The BLOCKS Multi-Functional Valve is designed for the filling of single and mixed types of gases. Through the patented and especially compact modular construction method, different valves can be produced according to the specific needs of individual customers. The BLOCKS system was certified for gas applications with oxygen up to 400 bar.
Valve ELLIPS Bevel seat cryo valve with s.s. bellow pneumatic or manual actuator
The specially shaped seat allows the free fluid stream in open position. Therefore the ELLIPS valves are very interesting when low flow resistance is required. The bevel seat valve ELLIPS is available from size 8 mm to 100 mm with an operating pressure of 25 bar and a temperature range to -253°C.
Valve FREES The new valve generation with minimal clearance volume
FREES offers more than 240% overall system performance compared with conventional vacuum insulated valves because it provides 3 benefits: Less pump cycles, better maintenance and reliability and more planning flexibility. FREES – the unique cryogenic valve with an innovative patented design.
Valve LOCKS® Tank globe valve for transport containers of hazardous goods
The newly developed bellow sealed valve LOCKS is suitable and approved as shut-off device for acid, toxic or explosive media. The valve is available as straight-through or angle type and is being offered with various connections.
Valve MAGROS The innovative springless non-return-valve
MAGROS is the reliable and high-quality springless non-return-valve, made from stainless steel, for gases and liquids at common temperatures, and with low pressure drop in open position. Reliable operation with low minimum cracking pressure. The valve body is made from solid stainless steel. Butt welded ends are the standard end connections.
Valve NOVIS The cost-effective valve series for cryogenic applications
The Novis valve series 500 from STÖHR ARMATUREN offers a standardised and cost-effective valve for cryogenic applications for liquid nitrogen temperature (77 K/ -196 °C). The series 500 has been designed for applications that do not require the complexity of vacuum jacketed installation.
Valve STICKS The cryogenic valve series for vacuum jacketed pipes and systems with insert concept
The insert design of the STICKS valves ensures high durability and compatibility for safe interchange. The insert concept allows system operators too quickly and simply exchange inserts and therefore the function of an existing system without effecting the vacuum insulation.
Valve UNIVERS The well-tried and reliable type for on-off valves and non-return valves.
The seat seals are selected according to the service fluids requirements in order to meet the customer’s specification. The way of actuating and the type of actuator is optional. Modifications like purge ports, leak detecting ports etc. are optional.
