Valve Remote Control system Actuator Hydraulic Power Unit (HPU) Solenoid Valve Cabinet

Actuator FOR OPERATION OF ANY QUARTERTURN(90°) VALVES

DOUBLE ACTING HYDRO-LOCK ACTUATOR

  • is designed to secure the valve hydraulically locked in its last order positions if there is any failure of hydraulic oil pressure.
  • Actuator is specifically designed with a compact rack and pinion configuration. It provides simple construction and constant output torque throughout the stroke.
Nominal Torque 180 ~ 12,000 Nm / 135 bar

SINGLE ACTING ACTUATOR

  • produces spring ending torque up to 23,000 Nm.
  • This hydraulic actuator provides reliable valve shutdown capability when an external power source is not available by spring return operation.

SCP (Self-Contained Powerpack)

  • is an electro-hydraulic local power pack directly mounted on the valve/actuator for remote control purpose.
  • This type does not require hydraulic pipes, needed solely electrical installation.

AMBIENT TEMPERATURE

  • RAP actuators are designed for operating temperature of -20°C to +80 °C as normal applications.
  • Optional high and low temperature of -45°C to +120 °C, respectively are available.
  • Special requirements can be supplied on request.
  • For higher and lower temperature applications, consult us.

VALVE INTERFACE

  • Valve mounting adaption in accordance with ISO 5211 mounting pattern.

RAP HYDRAULIC DOUBLE-ACTING ACTUATOR

ACTUATOR

  • Actuator type RAP is a double acting quarter turn and rack & pinion type actuators designed for all types of butterfly-, plug-, and ball valves.
  • A compact rack and pinion design provides simple construction and constant output torque throughout the stroke.
  • Full stroke adjustment screws are fitted to both end and turning in the stroke adjustment screws allows precise angular stroke adjustment between 85° and 95°
