The NORI 40 ZXLF / ZXSF is a metal-seated gland-packed globe valve for demanding applications in power plants, chemical and process plants. It offers high operational reliability, a long service life and meets all relevant standards. Ideal for water, steam and neutral media.
The gland packing is adjustable and therefore serviceable – for hermetic sealing to the outside the bellows version ZXLBV or ZXSBV should be specified. The temperature range extends to +450 °C.

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.
