Hayward® HRS Series Electric Actuators

Industrial-duty actuators for both non-alloy and alloy valves

 

Hayward industrial valve actuatorHayward's HRS series of industrial-duty valve actuators consist of three distinct designs:

 

  1. Electric actuation for on/off and proportional control

  2. Electric actuation for hazardous locations (Class I and ATEX compliant)

  3. Programmable electric actuation for On/Off and proportional control 

 

All three designs are used for standard ball valves, proportional control ball valves, 3-way ball valves and butterfly valves for sizes up to 24".  While we often match these actuators to Hayward valves, they can be used with alloy valves; their ISO 5211 mounting base simplifies installation onto most valves.  The available torque ranges from 440 to 44,250 in-lbs across five actuator sizes.

 

The basic and most commonly used version of the HRS actuator can be customized to operate on a range of AC and DC voltages (standard is 120v), actuation distance (from 0 to 180 degrees), additional auxiliary switches as well as proportional, timer control and feedback potentiometer control. 

 

hazardous location valve actuatorHazardous location valve actuators have the same design as the standard valve actuators except their enclosures and design satisfy  Class I and ATEX standards.  Class I is the North American standard and ATEX is considered a European standard:

Programmable (local control) Actuators

These valve actuators enable both stand alone operation (isolation from a PLC network) and use within a PLC network.  Variations include knob, push button, LCD indicator and LCD screen configurations.  The knob version has three LED indicators (power, open, closed) with a knob movement switch and key lock-out.  The push-button version enables toggling between remote and local modes, open/stop/close and five LED indicators (power, running open, fully open, running closed, fully closed).

 

The LED version has switches for model and position control with LED indicators for open, close, remote, local and fault indication. The LCD version displays the percentage of valve open and indicates when the actuator is moving and which direction it is moving.  Switches include control for mode and position control which operate in conjunction with LED indicators for local, remote, open and closed status.
