Precision in Motion
A Ballast Water Management System is only as effective as its ability to control the water flow. The actuator valves in a BSKY system direct water through treatment stages, manage bypass lines, and ensure safe drainage during shutdowns.
YAF Diesel supplies genuine BSKY Actuated Valves (valve body + actuator), engineered for corrosive seawater piping and thousands of maintenance-free cycles—support available via electric@yafdiesel.com.tr.
Critical Roles of the Actuator Valves
1) Automated Operational Modes
The BSKY PLC coordinates these valves to switch between Ballasting, De-ballasting, and Cleaning modes automatically. No manual valve turning is required—one touch on the control screen triggers the correct sequence of valve movements.
2) Safety Isolation & Bypass
During power failure or alarms, actuator valves return to a programmed safe state. Fail-safe logic helps prevent untreated water from entering tanks and protects the UV reactor from water hammer effects.
3) Precise Flow Regulation
Some BSKY models use modulating actuators to fine-tune flow based on UVI or pressure readings. If water clarity drops, the actuator can partially close to slow flow—helping ensure every drop receives the required UV dose.
Technical Advantages
We supply marine-grade valve bodies and actuators matched to BSKY logic and materials suitable for seawater exposure. Options depend on line size, pressure class, and installation zone (Standard / Ex).
| Feature | BSKY Actuator Valve Specification |
|---|---|
| Valve Type | High-performance Butterfly or Ball valves |
| Body Material | Ductile iron / Stainless steel / Aluminum bronze (seawater resistant) |
| Actuation | Pneumatic (rack & pinion) or Electric (multi-turn) |
| Feedback | Integrated limit switches for PLC open/closed status |
| Manual Override | Included as standard for emergency operation |
Solenoid Valve Compatibility
Matching 24VDC or 110/220VAC solenoids supplied for pneumatic actuators to ensure correct response and coil rating.
Corrosion Protection
Coatings (Rilsan/Epoxy), stainless discs, and suitable seat materials reduce marine growth and pitting risk.
The YAF Diesel Mechanical & Electrical Advantage

- Ex-ready options: ATEX/IECEx rated actuators and solenoids available for hazardous zones.
Frequently Asked Questions (FAQ)
Can I replace just the actuator without replacing the entire valve?
Yes. If the valve body is in good condition, we can supply only the pneumatic or electric actuator. We ensure the ISO 5211 mounting flange matches your existing valve.
What is the difference between Double Acting and Spring Return actuators?
Double Acting uses air to both open and close. Spring Return (fail-safe) uses air to open and an internal spring to return to a safe position if air pressure is lost. BSKY configuration depends on your ship’s safety logic.
Are these valves suitable for the Explosion-Proof (Ex) Series?
Yes. For tankers, we provide ATEX/IECEx certified actuators and solenoid valves designed for hazardous zones.
