Angle Seat Globe Valve

Metal

Construction
The GEMÜ 550 pneumatically operated 2/2 way angle seat globe
valve has a low maintenance piston actuator and PTFE seat
providing reliable operation.
The valve spindle is sealed by a self-adjusting gland packing
providing low maintenance and reliable valve spindle sealing even
after a long service life. The wiper ring fitted in front of the gland
packing protects the seal against contamination and damage.

Features
H Suitable for inert and corrosive* liquid and gaseous media
H Substantially reduced installation dimensions when using the
body with male threads which can be installed using union
nuts
H Materials of all medium wetted parts can be selected to suit
relevant applications

Advantages
H Stainless steel actuator
H Various types of valve body connections:
Threaded sockets, threaded spigots, butt weld spigots
H Good flow capability
H Extensive range of accessories
H Low weight
H The valve is easy to clean
