These actuators are most suitable for the actuation of quarter turn (90 Deg) / rotary valves like Ball Valves, Butterfly Valves or Plug Valves. They can be mounted directly on the valve shaft i.e. without the need of any intermediate gearbox. Being compact in size & weight, they are ideally suitable for the small size quarter turn valves. The main advantages of direct mounted quarter turn actuators are space & cost savings.

Torque Range : Min 0.2 Nm; Max 1000 Nm

Enclosure : Weather-proof & Explosion-proof

Power Supply : 115 VAC & 230 VAC-1Ph / 24 VDC / 415 VAC-3Ph

Closing Time : 6 Secs to 45 Secs

Duty : On-Off & Regulating

Fail-safe i.e. the valve can be driven to close or open position, in case of power supply failure.

Better Performance without Price Adder - New mechanical parts for the electrical quarter-turn actuators
Series PSQ proven in the field for over eight years.

The optimization of gear and casing allows several improvements at the quarter turn actuators PSQ. Most sizes are giving a higher torque due to increased efficiency, and the change in geometry allows longer valve shafts to be accomodated. Cost of material and assembly have been improved to ensure a continuously competitive price level.

Customers using PSQ/PSR quarter turn actuators and PSL linear actuators do profit from the simplicity
of the modular accessories in several ways, as fewer parts must be held in stock and the training requirements for the sales, service and assembly staff are reduced considerably.

1. Robust, compact and light weight design due to the use of high-quality aluminium die cast material.
2. Synchronous or brake motors without over-run, for precise positioning and mode of operation S4-1200 c/h.
3. ISO 5211 connection to valve and exchangeable drive bush of sintered metal.
4. Easy-to-see mechanical position indicator, adjustable.
5. Covered stop screws, easily adjustable +/- 5°.
6. Electrical limit switches that are easily adjustable.
7. Simple, continuously adjustable torque limi ting of 50 - 100 % in open and close directions (PSQ102 and bigger).
8. Comfortable hand operation without clutching from motor operation to manual operation; the handwheel is motionless when the motor is in operation and is always ready for operation.
9. Additional position switches.
10. Additional torque switches.
11. Single or double potentiometer.
12. Space heater.
13. Electronic position transmitter.
14. Electronic positioner.

PS Actuators have proven for more than 15 years in industry and ships, in water and sewage technology, in heating and air conditioning, in power station and boiler house plants.
They are especially renowned for their functional conception without unnecessary features that may be prone to failure, and for a precise positioning or controlling and long trouble-free operation.

Modular accessories, easy retrofitting even on site

The quarter-turn actuator series PSR is the economical addition to the proven actuator series PSQ for
torque requirements 15 Nm to 45 Nm, directly mounted as per ISO 5211. PSR series is containing a
maintenance-free, low-wear and low-noise spur gear resulting in high efficiency and long lifetime. PSR
with stroking time 30 sec are most suitable for control duty due the use of to synchronous motors
without after-run.

Customers who use the PSQ quarter-turn and PSL linear actuators profit from a standardisation of the
modular accessories in several ways, as fewer parts must be held in stock and the training requirements
for the sales, service and assembly staff are reduced considerably.

1. Tough, compact yet light-weighted design due to highquality aluminium body and UV-resistant polycarbonate cover.
2. Synchronous or brake motors without over-run, for precise positioning and mode of operation S4-1200 c/h.
3. ISO 5211 connection to valve and exchangeable drive bush of non-corrosive steel.
4. Easily visible mechanical position indicator.
5. Rotation angle 0-90°, one limit adjustable +/- 5°.
