Gemü’s globe valve with membrane actuator
February 2015
Valves, Actuators & Pump Control
The Gemü 536 pneumatically operated 2/2-way globe valve has a low maintenance membrane actuator which can be controlled by inert gaseous media. The valve plug is fixed to the spindle in such a way as to allow flexing during closure in order to ensure tight shut off. Steel and PTFE as well as a fibre glass-reinforced PTFE version are available as seats.
The valve spindle is sealed by a self-adjusting gland packing. This provides a low-maintenance and reliable valve spindle seal even after an extended period of operation. The wiper ring which has also been introduced additionally protects the gland packing from contamination and damage.
The customer has a choice between cast stainless steel 1.4408 or SG iron GGG40.3 (available from the beginning of 2015) for the material of the valve body. A flange in accordance with EN 1092 or ANSI cl. 125/150 RF is available for the piping connection.
A good flow rate and controllability is achieved due to the globe valve design. Standard regulating cages are used in the control valve design. Thanks to the high-quality design, Gemü 536 is also suitable for high operating temperatures and pressures. A version according to ATEX is also available as an option.
