Actuators

The 100 series actuators are designed for direct mounting into the STANADYNE “D” series injection pumps. These HT-100DB electric actuators create a high performance fuel injection system. The installation does not require any additional attachments or connecting rods. When the power supply is interrupted, the actuator also acts as a fuel shut-off.

KEY DATA

• The actuator fits integrally into the STANADYNE “D” pumps
• No additional attachments are required
• Acts as a fuel in the de-energised state Shutdown
• Faster response time compared to other systems

PERFORMANCE FEATURES

• Durable construction
• High reliability

The designation of the 103 series comprises the proven, proportional-acting actuators for integral mounting on the DELPHI DPB/DP2100 injection pumps. The mounting does not require any additional parts. In de-energised state, the 103 series actuators also function as fuel cut-off. This is made possible by an internal actuator return spring which moves the pump fuel metering valve to zero position when the power supply is interrupted.

• The actuator is directly mounted to the DELPHI injection pumps DPG/DP210
• No additional attachments are required
• Fast response time < 45msec
• Acts as a fuel in the de-energised state Shutdown

The 225 Series electric actuator is an electromechanical rotary armature adjuster with linear, proportional characteristics. It is particularly suitable for precise control of the fuel quantity. An internal spring ensures safe shutdown when the power supply is switched off. This design results in fast reaction time, large adjustment angle and high reliability. The faster reaction time compared to other products results in much better dynamic running precision. The range of applications includes injection pumps with or without mechanical governors, rotary injection pumps and medium-sized gas engines. The adjustment angle of 25° allows very versatile applications.

KEY DATA

• Easy installation
• Universal desig
• Integrated return spring
• Fast dynamic reaction time
• Versatile installation positions
• Torque of 2.2 lb.ft (2.7Nm)
• 25° angle of rotation

PERFORMANCE FEATURES

• Durable construction
• High reliability

The 275 series actuators fit exactly to the BOSCH injection pumps type “P” and “RP2”, in place of the mechanical governor. The 275 actuator on the injection pump creates a high performance fuel control system without external rods. An external lever on the actuator allows the control to be overridden at any time. The actuator also contains an internal limitation of the maximum injection quantity.

KEY FIGURES

• Feedback signal Control possible
• Replaces the mechanical regulator of the BOSCH types “P” and RP21″.
• Can control up to 16 cylinder pumps
• High reliability, no sliding parts, fully enclosed
• Moves the control rod directly
• Includes manual control rod override
• Feedback signal sensor and high-performance bearing system possible
• Optimum control performance for in-line pumps

The integral actuators of the HT-FLR-190 series were developed for direct mounting on smaller diesel engines. No external rods or brackets are required for mounting. When de-energised, the HT-FLR-190 actuators also act as an engine shutdown, which is made possible by the internal spring-loaded control.

By mounting the HT-FLR-190 actuator the existing mechanical controller is not switched off. By increasing its speed by 200-300 rpm above the desired nominal speed of the electronic governor, the mechanical governor then acts as overspeed safety protection.

The construction of the HT-FLR-190 electromechanical governor is based on the well-proven proportional control technology.

KEY DATA

• Inexpensive integral actuator
• Tried and tested electromechanical technology with high reliability
• Simple installation, short adjustment procedure
• Very fast response time
• All just metal parts, sealed against the outside
• Versatile functionality
• Integrated, safe design
