Globe Control Valve,

Metal

Construction
The GEMÜ 534 2/2-way globe control valve is designed for demanding
flow control applications. It can be paired with the GEMÜ 1434 µPos,
GEMÜ 1435 ePos positioners or the GEMÜ 1436 cPos positioner and
process controller dependent on the control requirements (for features
see page 8). The positioners are specially designed for GEMÜ valves and
achieve optimum results when used as a system. The valve spindle is
sealed by a self-adjusting gland packing providing low maintenance and
reliable sealing even after a long service life with high cycle duties. GEMÜ 534
A wiper ring protects the gland packing against contamination and damage. + 1434 µPos

Features
• Linear or modified equal-percentage control characteristics
• Kv values from approx. 0.16 - 140 m³/h, depending on nominal size,
valve seat and regulating cone design
• PID control system can be implemented with GEMÜ 1436
• Suitable for inert, corrosive*, liquid and gaseous media and steam
• Flanged bodies in SG iron GGG 40.3 and stainless steel 1.4408 to
EN 1092 and ANSI 125/150
• Valve body DN 15 - 100, pressure rating to PN 40
• Max. operating temperature 180°C

Advantages
• Simple and fast commissioning
• Valve and positioner are optimally adapted to each other.
(For positioner details please refer to the relevant data sheets)
GEMÜ 534
• Standard gland packing suitable for vacuum up to 20 mbar (abs.) + 1435 ePos
