Regeltek Actuators for Diaphragm Valves

Regeltek series actuators can be used for Diaphragm valves for ON/OFF and Regulating duty. These can be directly mounted, as shown in the photograph, so as to give linear motion to the valve stem. Following table can be used as a guide line for the actuator selection; however, it is advisable to confirm the exact requirement of thrust values from the valve manufacturers for the proper selection of the actuators.

Accessories for Regeltek Actuators

Following optional extra accessories available in all the models of Regeltek actuators.

Travel Limit Switches:
Two additional travel limit switches with 1 NO + 1 NC changeover potential free contacts can be provided.

Feed back Potentiometer:
Maximum two feed back potentiometers can be provided to give the out put of change in resistance with respect to the mechanical movement of the actuator out put shaft.

Position Transmitter -Model PPT-200:
This unit converts resistance out put from the Potentiometers into the control signal of 4-20 mA thru a two wire system. This is an actuator mounted instrument having a facility of SPAN/ZERO adjustment. This requires external power supply of 12 to 36 V D C.

Electronic Positioner - Model PP500 :
This unit helps in achieving the exact mechanical position of the actuator out put spindle with respect to the incoming control signal of 4-20 mA or 0-1 0 V D C. The unit has facilities for SPAN/ZERO and Dead band adjustments and LED indications for Open/Close functions & fault operations.

The unit is available in field /mounted and Panel mounted versions.
Control Panel cum Positioner - Model PP500:

Control Panel cum Positioner - Model PP500:
This unit has an inbuilt Positioner PP300 with all its normal and following additional features:

  • Auto-Manual selector switch - In Auto mode the actuator operates as per the incoming control command and in Manual mode it can be operated manually by switch.
  • Digital Indicator: - (3/1/2 Digit) This Indicates the percentage opening of the final control element.
  • LED indications for opened/closed, power-on, Fuse blown.
  • 4-20 mA output for customer use.

Manual Loader: Manual Loader:
This is a simple control panel having an Auto Manual selector switch, Open/Close push buttons, opened/closed LED indications, and percentage opening digital indicator.
