1 532 Globe Valve, MetalConstructionThe GEM 532 pneumatically operated 2/2-way valve has a robust 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 it against contamination and Suitable for inert and corrosive* liquid and gaseous media Standard floating plug on spindle ensures excellent seat sealing Valve bodies available in SG iron and stainless steel Flanged versions Customized control valve versions availableAdvantages Robust aluminium actuator Good flow capability and compact design Accessories.
