Schubert & Salzer is extending its range of sterile and aseptic valves by two new types of hygienic angle seat valves . |
The shut-off valve type 7015 and the control valve type 7025 with integrated digital positioner are specially adapted for use in the production of food and beverages . These valves are used to control and shut off product streams , drinking water , CO2 and nitrogen , as well as sterile steam and sterile air . The new valve types in the nominal sizes DN 15-50 and the pressure class PN 40 are suitable for media with temperatures from – 30 ° C to + 170 ° C and in special versions even from – 50 ° C to + 180 ° C . All wetted plastics are FDAcompliant and conform to the EC Regulation 1935 / 2004 as well as the EU Plastic Regulation 10 / 2011 . Both valve types meet the requirements according to the Technical Instructions on Air Quality Control ( 12-2021 ) together with EN ISO 15848- 1:2017 . |
Marotta Controls , a rapidly growing aerospace and defense supplier with a 65-year-plus heritage in spaceflight , has been selected by NASA ’ s Jet Propulsion Laboratory ( JPL ) to supply two types of valves on the Sample Retrieval Lander ( SRL ), a key element of NASA ’ s Mars Sample Return program . The SRL will carry the Mars Ascent Vehicle ( MAV ), a rocket charged with launching samples off the surface of Mars for return to Earth for study . The NASA SRL will utilize two different components from Marotta . The first is a customized valve |
based on the MV130HLT , a heritage design from Marotta ’ s CoRe ® Flow Control series . This valve will pressurize the liquid propellant tanks , starting the SRL ’ s engines . The second Marotta valve , the SPV795 , is brand new and designed specifically to shut off the SRL ’ s descent engines to facilitate a safe landing ; this is to accommodate the very thin atmosphere on Mars ( which is less than 1 % as dense as that of Earth ). Both valves have been optimized to reduce the risk of sample contamination and safeguard the integrity of each vial ’ s contents . |
