Angle Seat Globe Valve, Metal Construction The GEMÜ pneumatically operated 2/2 way angle seat globe valve has a low maintenance aluminium piston actuator. The valve spindle is sealed by a selfadjusting 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 Substantially reduced installation dimensions when using the body with male threads which can be removed using union nuts Suitable for high working temperatures and pressures Control medium connection can be rotated through 3 Advantages Various valve body connections: threaded sockets, threaded spigots, butt weld spigots Good flow capability due to angle seat design Extensive range of accessories 0 + 3 + 4 2 Actuator dimensions (mm) ø B 7 6 64 e M 6x M 6x M x M x F 8. 23 7 Installation dimensions see page 3. * Connection only for actuators, 2 and, c.f. 2 and 3
