The BTA Difference

Why This Is Not Another Timer

Three engineering principles that separate the TSV from hobby-grade timers and battery-powered alternatives.

⚡

240V Industrial Power

Unlike 12V toys and battery-powered timers that fail when it matters, the TSV runs on 240V mains power — the same reliability standard used in industrial process control. Consistent. Powerful. Dependable.

🔄

Triple-Purpose Automation

One unit handles Automated Wash Down (AWD), Auto Water Change (AWC), and Auto Dosing. No separate controllers. No duplicate plumbing. One install, three critical automation functions.

🎯

Precision Digital Control

ON-Time and OFF-Time adjustable from 0.01 seconds to 99 hours — not coarse mechanical dials. Pre-programmed from the factory with a 3-second burst every 30 minutes. Plug in and go.

Features & Benefits

Built for Professionals. Engineered for Reliability.

Every detail designed for serious aquatic systems — from the zero-differential solenoid to the saltwater-safe seals.

Ultra-Wide Timer Range

0.01 sec to 99 hrs ON and OFF times. Covers every application from rapid skimmer bursts to slow drip water changes to precise dosing schedules.

Zero Differential Solenoid

No minimum pressure required. Opens fully regardless of line pressure. Reliable operation from 0 to 6 Bar.

Saltwater Safe Construction

FKM (Viton) seals and glass-reinforced nylon body. Rated for freshwater, saltwater, and chemical dosing solutions.

Pre-Assembled & Pre-Programmed

Arrives fully assembled and factory-set to a 3-second burst every 30 minutes. Install, plumb, power on — done.

Standard 3/4" BSP Fittings

20mm orifice with standard 3/4" BSP threads. Plumbs directly into existing lines — no adapters or custom fittings needed.

Normally Closed Design

Solenoid is normally closed — if power is lost, the valve shuts. Fail-safe by design. No flooding or overdosing risk.

Glass-Reinforced Nylon Body

Chemical-resistant, impact-resistant, and corrosion-proof. Built for the harsh environment around sumps, skimmers, and dosing stations.

Triple Purpose: AWD + AWC + Dosing

One TSV automates skimmer washdown, water changes, and dosing — three manual chores eliminated with a single install.

How It Works

Set It. Forget It. Stay Stable.

One unit. Three critical automation tasks. Four simple steps to hands-free system maintenance.

01
Program Your Cycle
Set two parameters: the ON-Time (how long the valve stays open) and the OFF-Time (interval between events). Both adjustable from 0.01 seconds to 99 hours.
02
Automated Activation
At the end of your programmed OFF-Time, the timer energizes the industrial-grade solenoid valve, causing it to open automatically.
03
Flow Occurs
AWD Mode: Powerful spray washes skimmer neck. AWC Mode: Precise water volume enters the system. Dosing Mode: Exact liquid dose delivered on schedule.
04
Reset & Wait
The solenoid closes, and the timer begins counting down the OFF-Time until the next cycle. Fully automatic. Zero intervention.

Who It's For

Built for Serious Aquatic Systems

From reef aquariums to commercial aquaculture — if automation matters, the TSV delivers.

🦘

Reef & Marine Aquariums

Organic film on the skimmer neck kills foam production. Automated washdowns keep your protein skimmer at peak efficiency — maximum waste export, crystal-clear water, stable parameters. Also ideal for automated top-off and kalkwasser dosing.

🐟

Large Display & FOWLR

Consistent, automated water changes without the manual labour. Program precise volumes on precise schedules — stable chemistry around the clock, even when you're not there. Add automated supplement dosing on the same unit.

🧪

Aquaculture, RAS & Labs

Industrial-grade 240V construction handles continuous-duty commercial systems — hatcheries, grow-out, live holding, and research facilities. Ideal for automated media dosing, disinfectant injection, and pH buffer delivery. Zero-differential operation from 0 Bar.

FAQ

Frequently Asked Questions

Q What can I use the TSV for?
The TSV is a triple-purpose automation controller. Use it for AWD (Auto Wash Down) — automated skimmer neck cleaning. AWC (Auto Water Change) — precise scheduled water replacement. Auto Dosing — timed liquid additive delivery. One unit covers all three applications.
Q Why 240V instead of 12V or battery?
Because reliability matters. 240V mains power delivers consistent, powerful solenoid activation — every cycle, every time. 12V systems can underperform under load. Batteries fail silently. Mains power is what industrial and commercial systems rely on.
Q What does "Zero Differential" mean?
A zero-differential solenoid opens fully regardless of the pressure difference across the valve. This means no minimum line pressure is required for the valve to operate — it works from 0 Bar right through to 6 Bar. Essential for gravity-fed dosing and low-pressure AWC systems.
Q Is it safe for saltwater and dosing chemicals?
Yes. The valve uses FKM (Viton) seals and a glass-reinforced nylon body — both materials are fully saltwater compatible and resist common dosing solutions including kalkwasser, calcium, alkalinity, and magnesium supplements.
Q What does "Normally Closed" mean?
Normally closed means the solenoid valve stays shut when unpowered. If the power fails, the valve closes automatically — no water flows, no dosing overflow, no flooding risk. Fail-safe by design.
Q How do I program the timer for dosing?
The digital timer has simple button controls to set the ON-Time (how long the valve stays open — determines dose volume) and OFF-Time (interval between doses). Both adjustable from 0.01 seconds to 99 hours. For precise dosing volumes, calibrate flow rate and calculate ON-Time accordingly.
Q Does it come with fittings and plumbing?
The unit has standard 3/4" BSP threaded ports (20mm orifice). It plumbs directly into your existing line using standard BSP fittings (not included). The pre-assembled unit includes the timer, solenoid, and housing.
Q Do I need an electrician to install it?
Yes. This unit requires hard-wiring to a 240V power source by a qualified electrician. It is not a plug-and-play device. This ensures safe, code-compliant installation and reliable long-term operation.
Q Can I use the TSV for multiple applications at once?
The single solenoid valve can be plumbed to serve one output line at a time. If you need AWD, AWC, and dosing running simultaneously on independent schedules, multiple TSV units would be required — each with independent timer and solenoid control.
