OPTIMUS DISTRIBUTORActuated valves that arrive matched, mounted and tested
Valve actuators automate the valves Optimus Distributor supplies: pneumatic and electric quarter-turn units for ball and butterfly valves, multi-turn drives for gate and globe patterns. Our engineers select torque, fail action and control interface against the valve's own figures. The package arrives matched, mounted and tested, not assembled ad hoc on site.

What we automate
Any quarter-turn valve in the catalogue is a candidate for actuation. Ball and butterfly patterns take a rotary actuator straight onto an ISO mounting pad. Multi-turn drives cover the rising-stem side: gate and globe valves whose stems turn many revolutions between open and closed. The valves come from the same racks as everything else we sell, the KITZ line first among them, and the same rotary logic reaches beyond pipe to duct, where DTL industrial dampers use the same actuator families. The catalogue carries 23 actuator line items plus 5 dedicated butterfly valve actuator line items.
Pneumatic or electric: the real trade
Two questions settle it: which utility does the site already run, and what must the valve do when that utility fails? Pneumatic actuators are simple, fast and cheap to keep cycling, but they need instrument air. Their gift is the spring-return option that drives the valve to a safe position on air failure, with no electronics involved. Electric actuators need only a cable, position precisely and talk to a control system directly. On power failure a standard unit stops where it is, so fail-safe behaviour has to be bought deliberately. Decide failure behaviour first, then let speed, duty cycle and utilities settle the rest.
Three actuation families, side by side
| Family | Speed | Fail action | Utilities needed | Typical valves |
|---|---|---|---|---|
| Pneumatic quarter-turn | Fast: full stroke in seconds | Spring-return gives true fail-open or fail-closed on air loss | Instrument air supply; solenoid and positioner as required | Ball and butterfly valves; quarter-turn dampers |
| Electric quarter-turn | Moderate: geared travel, precise positioning | Stays in last position on power loss unless spring-return or battery-backed | Power supply and control cabling only | Ball and butterfly valves in HVAC and process control |
| Multi-turn (electric) | Slow by design: many stem revolutions per stroke | Stays in last position; handwheel override for manual recovery | Power supply, control cabling, torque/limit settings | Gate and globe valves on isolation and regulation duty |
Guidance is general actuation engineering practice; line-item counts are our own catalogue counts across all brands in each category. Torque figures, supply pressures and voltages for a specific package come from the datasheets, and we confirm them against your purchase order at quotation.
Open, closed, or last position: decide it first
Fail action cannot be retrofitted with a settings change. It is built into the hardware you buy. Work it out from the process, not the catalogue: what should this line do at the worst possible moment?
- Fail-closed: the default for fuel, steam and anything that must stop when control is lost
- Fail-open: for cooling flows and relief paths that must keep running unattended
- Fail-in-place: acceptable where holding the last position is safe, common on electric units
- Manual recovery: handwheels and declutchable overrides decide how you operate through an outage
The duty-first habit applies here as it does to the valve itself. The reasoning is in choosing the right industrial valve.
Sizing torque with margin
An actuator is sized against the valve's real torque demand: seating and unseating torque at the actual differential pressure, not bench friction. Good practice adds a safety factor on top. Torque demand grows in service as seats swell and media leaves deposits. Undersize it and the actuator stalls when the process needs the valve to move. Oversize it and you pay more, hang weight on the pipe and hammer the seat on every close. We run that calculation with the valve's own figures in hand, one advantage of packaging the right isolation valve and its actuator from a single counter.
Mounted and tested before it ships
Buying an actuated package instead of parts settles who owns the interface. We sit down with your engineers so the assembly fits the service: bracket and coupling matched to the mounting pad, travel stops set, fail action verified, and the unit stroked before it leaves Subang Jaya. What lands on site bolts into the line and answers to the control system. No adaptor fabrication, no guesswork about rotation or stops.
An actuated-valve enquiry moves fastest when it arrives complete. Send these with the WhatsApp message or through any contact channel:
- Valve figure or type and size, or the duty and we propose the valve too
- Operating and maximum differential pressure across the closed valve
- Available utility: instrument air pressure, or supply voltage and phase
- Required fail action: open, closed, or last position
- Control signal: on/off, modulating, and any position feedback needed
- Cycles per hour or day, and the environment the actuator lives in
