Hydraulic actuator HB series

linearfor gate valveswith integrated position sensor

The actively-cooled HB hydraulic actuator series is bolted onto the manifold. Each Actuator is available with optional Thermocouple (TC) and patented Position Sensor (PS). The Position Sensor detects pin position and sends a signal to activeGate® products providing closed loop position control or pin position indication and speed monitoring with Valve Monitoring Interface (VMI). All HB series actuators are provided with the following features: ♦ Automatic bleed for air removal in Hydraulic lines to provide consistent actuation ♦ Easy Valve Pin adjustment through cutout in top clamp plate ♦ Valve Pin quick coupling ♦ Valve Pin anti-rotation feature Note: An oil filter with a rating of 10 micron or smaller is required in order to ensure proper automatic bleed performance. Cooling the Actuator The cooling plate between the Actuator and the manifold (not shown) provides active cooling of the needle guide and the Actuator to thermally separate it from the hot manifold surface. A maximum of three Actuators can be plumbed in series to create an independent cooling circuit to prevent overheating of the Actuators. Maintaining Actuator cooling after end of production for fifteen minutes will protect against overheating. Cooling Plate (B) can be rotated independently of the Actuator Housing (A). Note: SynCool® 1 option is available to eliminate post-cooling requirement for many applications (see page 20 for more information).
