The GEMU 514 2/2-way angle seat globe valve has a low maintenance aluminium piston actuator and is pneumatically operated. The valve spindle is sealed by a self-adjusting gland packing providing low maintenance and reliable valve spindle sealing even after long service life. A wiper ring fitted in front of the gland packing protects the seal against contamination and damage.
Features
- Robust actuator housing made of aluminium
- Suitable for corrosive, inert, gaseous and liquid media and steam
- Linear or modified equal-percentage control characteristics
- High flow rates due to angle seat design, Kv values from approx. 0.16 – 60.0 m³/h, depending on nominal size, valve seat and regulating cone design
- Stainless steel bellows as spindle seal for high operating temperatures
- Special connections and materials on request
- Suitable for vacuum up to 20 mbar (a)
- PID control system can be implemented with GEMU1436 cPos
Advantages
- Simple and fast commissioning
- Good flow capability and compact design
