Globe Control Valve, Metal

Transcription

1 Globe Control Valve, Metal Construction The GEMÜ /-way globe control valve is designed for demanding flow control applications. It can be paired with the GEMÜ 434 µpos, GEMÜ 435 epos positioners or the GEMÜ 436 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. A wiper ring protects the gland packing against contamination and damage. GEMÜ µpos Features Linear or modified equal-percentage control characteristics Kv values from approx m³/h, depending on nominal size, valve seat and regulating cone design PID control system can be implemented with GEMÜ 436 Suitable for inert, corrosive*, liquid and gaseous media and steam Flanged bodies in SG iron GGG 40.3 and stainless steel.4408 to EN 09 and ANSI 5/50 Valve body 5-00, pressure rating to PN 40 Max. operating temperature 80 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) Standard gland packing suitable for vacuum up to 0 mbar (abs.)
