The NORI 40 ZXLBV / ZXSBV is a metal-seated bellows-sealed globe valve for demanding applications in power plants, chemical and process plants. It offers maximum tightness, a long service life and meets all relevant standards. Ideal for water, steam and thermal oil.
The bellows replaces the gland packing and makes the stem sealing maintenance-free – that is the reason why this version is chosen for thermal oil and TA Luft relevant media.

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.
