The electrically controlled hydraulic amplifier is a pilot operated, linear servo actuator used in conjunction with the Woodward 2301, 500 Series or NetCon\u00ae electronic controls. The amplifier contains a Woodward EG-3P actuator which converts the electric control signal to a rotary output which controls the servo output position taken by the amplifier. The amplifier is capable of operating the control mechanisms for steam turbines or large engines which require relatively large forces and work capacity beyond that of the actuators normally used with 2301, 500 Series, and NetCon controls. <\/p>\n

Two models of this type amplifier are available. The large 7.25 inch (184 mm) and the smaller 5.25 inch (133 mm) models are basically the same except for the diameter of their servo pistons. The 7.25 inch model is capable of developing about twice the force and over double the work capacity of the 5.25 inch model under the same operating conditions. Either size amplifier may operate as single-acting or differential (double-acting). The single-acting is pressure actuated in the increase fuel direction and spring loaded in the decrease fuel direction. Pressure oil moves the differential servo in both increase and decrease directions. The differential amplifier normally has a light return spring to ensure closing the valve during shutdown.<\/p>\n","protected":false},"featured_media":249,"comment_status":"closed","ping_status":"closed","template":"","meta":[],"product_brand":[],"product_cat":[26],"product_tag":[],"class_list":{"0":"post-324","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-governor","8":"first","9":"instock","10":"shipping-taxable","11":"product-type-simple"},"yoast_head":"\nHydraulic Amplifier - matsudagovernor<\/title>\n<meta name=\"robots\" content=\"noindex, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<meta property=\"og:locale\" content=\"th_TH\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"Hydraulic Amplifier - matsudagovernor\" \/>\n<meta property=\"og:description\" content=\"Two models of this type amplifier are available.
