Electric Valve Actuators: The Smart Solution for Modern Systems

Managing water supply, heating, or energy-saving projects is hard. Old ways use too much power, waste water, or break down too soon. When systems stop, people lose comfort, money, and trust. Most companies cannot watch every pipe, valve, or control all the time.If a single valve fails, it can cause leaks, waste, and costly downtime. Picture a big city’s water plant: if just one valve won’t close, it can waste up to 15% of chemicals and send labor costs soaring by 67%. Leaks and mistakes hurt profits and are bad for the planet.

Many old valve actuators need lots of hands-on work. They are slow, use lots of energy, and may cause more pollution. In oil, gas, and water plants, downtime can even mean safety risks. Smart city projects and green energy goals make these problems even bigger.

Some plants spend over $12,000 a year just to fix and check pneumatic valves. In contrast, electric valve actuators can bring these costs down by 71%. And smart, IoT-connected actuators help spot problems before they happen, making sure nothing stops working when you need it most.

Smart Solution: Electric Valve Actuators

Electric valve actuators are small but mighty. They use electric power to open or close valves, turn flow up or down, and help save water and energy. You can find them everywhere—from city water plants and heating networks to oil & gas pipelines and modern HVAC.

How They Work

Parts of an Electric Valve Actuator:

• Electric Motor: Moves the valve, using AC or DC power.
• Gearbox: Makes the motor stronger to handle big valves.
• Position Sensors: Tells you if the valve is open, closed, or stuck.
• Smart Controller: Lets you manage everything from a phone or computer (using PLC, Modbus, HART).

Electric vs Pneumatic or Hydraulic Actuators

A Shell LNG plant switched to electric actuators, cutting maintenance costs by 71% and CO2 emissions by 81%. Smart, right?

Choosing the Right Actuator

Key Points for Pickers:

• Valve Size & Type: Ball, butterfly, globe, or rotary?
• Torque Needed: 6-inch ball valves: need 300–450 Nm.
• Power Supply: 24V DC or 220V AC?
• Control Signals: 4-20mA, RS485, Modbus?
• Ingress Protection: IP/NEMA/ATEX? Must for wet or risk areas.
• Certifications: SIL2/3, API 6D for top safety.

Real Example:
When a water plant used automated electric actuators, manual valve checks dropped from 120 times per day to just 4. Chemical waste dropped 80%, labor costs by 67%.

At a Glance: Savings & Efficiency

Fun Stat:
28% of field failures are simply from under-torqued actuators. Pick wisely!

Installation & Maintenance: Made Simple

Steps for Seamless Setup:

1. Align with ISO 5211 plates.
2. Set up position sensors.
3. Run factory self-tests.
4. Connect to control dashboard.
5. Check fail-safe settings (battery/spring).

Navarch tests every single actuator again and again before it leaves the factory. Our products are efficient, safe, and built to last. The smart factory produces up to 8,000 tons of valves each year—enough to power big city grids or massive water plants.
