When it comes to mining or the production and processing of steel, having the right valve in the right place is essential if things are to run smoothly. Of course it is important to consider whether the valve comes into direct contact with the medium or whether it is more indirectly concerned with the process. But while the requirements may vary depending on where a valve is used, they are always high: process-stability, long-lasting life time, easy maintenance and precise control are just a few examples. With Schubert & Salzer Control Systems valves, you can be sure you have made the right...

When it comes to precise control of liquid and gaseous media, sliding gate valves are particularly suitable as the superior alternative to globe valves, even at very high or low temperatures, high pressures or if rapid switching actions, a high degree of control precision or rangeability are needed. Users appreciate the significantly lower consumption of energy due to the smaller actuator and extremely short valve stroke of 6-9 mm. A typical application is the control of O/natural gas in smelting furnaces, also cooling water control in the continuous casting process; the control of N2 for...

The seat valves are ideal when liquid and gaseous media need to be shut off securely and without closing impact. Gases principally used in metallurgy include O2, H2, natural gas, argon and N2. Also water, oils, fuels, emulsions, chemicals or even steam are used. A special application is the control of compressed air in core blowing equipment. Summary of your benefits: • Long lasting and highly leakproof (especially compared to ball valves, which are typically with a floating ball and which wear the seal with every stroke) up to leakage class VI. • Very simple to maintain: when servicing the...

Schubert & Salzer’s ball sector valves have proved themselves particularly as control valves for abrasive, particle-loaded, dusty, viscous and crystallising media. • The special ball design provides self-cleaning when crystallisation and build-ups in the valve body occur. • Highest control level with a rangeability of 300:1. • Bi-directional flow possible • Material combination tailored to the application. • Hard chrome plating and stellite seats for highly abrasive applications. • TA Luft-certified shaft seal possible by double O-ring design. • Low actuation forces. • Modular design of...
