Document Type and Number:
Japanese Patent JP2001503834
Kind Code:
A
Abstract:
Electro-pneumatic positioner with a pneumatically driven dual-chamber actuator having a pneumatic main air intake valve and a pneumatic main air discharge valve attached to a pressure pipe of the actuator. The positioner may also include a further main air intake valve and a further main air discharge valve attached to a further pressure pipe of the actuator. Each main valve has an actuating element, with the actuating element for the one and the further main air intake valves each being formed by a corresponding main valve. To manufacture an electro-pneumatic positioner of this type comparatively economically, the actuating element of the one main air discharge valve is formed by a feed pipe which connects the pressurized side of the one main air discharge valve to the interior of the reversing valve of the further main air intake valve. The actuating element of the further main air discharge valve is formed by a further feed pipe which leads from the pressurized side of this main air discharge valve to the reversing valve of the one main air intake valve.
