GEMU Model 514 Angle Seated Globe Valve – Metal


The GEMU 514 pneumatically operated 2/2 way angle seat globe valve has a low maintenance aluminium piston actuator. 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.
