Together with our strong partners, we develop customized automation solutions for globe valves. Whether pneumatic or electric actuators, positioners, limit switches or solenoid valves – we offer complete systems from a single source.
Our globe valves can be individually equipped with high-quality stainless steel heating and leakage jackets. These enable the safe heating, temperature control and leakage monitoring of viscous, temperature-dependent or safety-critical media.
Thanks to our customized design, we adapt each jacket precisely to the respective valve – including production, welding, connection assembly and leak testing. We can provide suitable valves directly on request. Ideal for the process industry, chemicals, energy, food technology and wherever process reliability and constant media conditions are crucial.
DIN EN 558-1, DIN EN 1092, DIN EN 12266, optional TA-Luft and ISO 15848.
For aggressive and non-aggressive liquids, gases and steam.
Yes, ATEX-compliant versions are available.
Standard: -10 °C to +400 °C.
Yes, according to VDI 2440 and ISO 15848.
Our insulations are more than just accessories – they perfectly complement valves and systems and increase efficiency, safety and adaptability.
