Construction
The GEMU 312/314 pneumatically operated 3/2-way valves have a rugged low maintenance aluminium piston actuator.
GEMU 312 is flanged, GEMU 314 has threaded sockets. The connection for the control medium can be rotated through 360°. The double sided valve plug is connected to the actuator via a spindle. 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. A wiper ring fitted in front of the gland packing protects the seal against contamination and damage.
