Belz electric actuator three way control valve for conduction oil

Belz electric actuator three way control valve for conduction oil

Short Description:

Three way Flange type Electric Control Valve for Heat Oil Transfer Heat water.The Valve offers numerous benefits over other control valves including long life stem seals proven millions of times over,
flexible changeable trims offering multiple Kvs values per body size, precise and durable operation (even at high differential pressures) thanks to the vibration reducing shaft guiding, easy handling, the small footprint, rotatable upper part and reduced weight when compared with other control valves.

Product Detail

Product Tags

Suitable for non-critical complex control tasks uses in applications such as industrial complexes, plant construction and process
technology installations for mediums such as cooling water, cooling brine, warm water, hot water and steam.
Offered as standard in the trim with Cast Iron Body, Stainless Steel Trim and the Spring-Loaded PTFE V-Ring unit complete with
electric actuator with integrated positioner unit. Options available upon request include different trim materials, parabolic
plugs with PTFE seats, miniature Kvs values, increased tightness on seats i.e. Class IV leakage rate.
If you are not sure of the size, you require for your process please do not hesitate to get in contact with our Technical Sales
team who will be able to size the correct valve for your process.
