Product Features (with Supporting Copy)
Immediate Shutoff on Leak Detection — No Delay, No Manual Intervention
The valve responds to the gas detector signal and closes flow instantly. No on-site personnel required, no waiting for manual intervention — protection operates even when the facility is unattended.
3/4" Size — Higher Flow, Zero Restriction
The difference between 1/2" and 3/4" is not just diameter — it's the capacity to serve main supply lines and high-consumption gas appliances without restricting flow or causing pressure drops at end points.

Tecno Control is an Italian brand specializing in gas safety devices. Design and manufacturing are calibrated for continuous-duty environments in restaurants, factories, and commercial buildings where equipment failure is not an option.
IP65 Protection — Indoor and Outdoor Use in All Conditions
IP65 means full dust protection and water spray protection from all directions. The valve performs at the same standard in a wet commercial kitchen, a boiler room, or an exposed outdoor installation point.
6-Bar Pressure Tolerance — Handles the Most Demanding Gas Lines
6-bar operating pressure makes this valve suitable for all natural gas and LPG applications in commercial and industrial facilities without restriction.
230V / 50–60 Hz Operation — Direct Grid Compatibility
Standard voltage specification means the valve connects directly to the local power grid with no transformer or voltage converter required.
Direct Installation — No Line Modifications Required
The valve installs on the existing gas line at the main supply point and connects to the gas detector. No structural modifications to the line, no exceptional installation requirements.
Use Cases
Main Supply Lines in Residential Buildings and Complexes The main gas line supplying one unit or multiple units requires a valve sized to match the required flow. 3/4" is the most common standard for main supply lines in residential buildings.
Restaurants and High-Load Commercial Kitchens A commercial kitchen running multi-burner ranges, industrial ovens, and commercial water heaters needs a high-flow supply line. A 3/4" valve protects that line without any flow restriction during peak operation hours.
Boiler Rooms and Central Heating Systems Large boilers operate at higher pressures and flow rates than residential appliances. The 3/4" automatic shutoff valve installs on the supply line and restores safety to the entire heating system in the event of any leak.
Light Industrial Facilities and Gas-Powered Workshops Gas welding workshops, glass manufacturing facilities, and any light industrial facility using gas as a primary energy source require protection scaled to larger supply line sizes.
Commercial HVAC Systems Air drying equipment and industrial cooling systems that use gas as fuel typically operate on 3/4" lines — the automatic valve integrates into these systems without modification to the existing infrastructure.
Outdoor and Semi-Outdoor Installation Points IP65 rating makes the valve suitable for installation in locations exposed to dust and moisture — such as outdoor meter points or partially ventilated gas rooms.
Installation Guide (Step-by-Step)
Step 1 — Shut Off Gas Supply Completely Stop gas flow from the main source before any work on the line. Verify zero residual pressure before loosening any fitting.
Step 2 — Identify the Installation Point on the Supply Line Choose a point on the 3/4" line close to the main feed, accessible for inspection and maintenance. Ideally upstream of any branch connections.
Step 3 — Verify Flow Direction Marked on the Valve The valve has a clearly marked flow direction arrow. Reverse installation disables valve function. Verify direction before making connections.
Step 4 — Install the Valve on the Line with Appropriate Fittings Use standard 3/4" gas fittings and tighten to appropriate torque. Use only sealing compounds rated for gas line use.
Step 5 — Connect Power per 230V / 50–60 Hz Specification Connect the valve to an appropriate power source on a dedicated circuit — ideally wired directly to the gas detector per the included wiring diagram.
Step 6 — Connect the Gas Detector to the Valve Follow the electrical wiring diagram to connect the detector signal to the valve's control input. When the detector identifies a leak, it sends a signal that closes the valve immediately.
Step 7 — Restore Gas Supply and Test for Leaks Slowly reopen the gas supply and inspect all connections with soapy water or a leak detection solution. Any bubbling indicates a leak that must be resolved before operation.
Step 8 — Test Valve Response Manually trigger the gas detector and verify the valve closes immediately. This test is mandatory before the system is considered operational.
Performance Tips
- Test valve response every 3 months by manually triggering the gas detector — periodic testing ensures the valve functions when genuinely needed.
- Document the valve installation date and all inspection intervals in a maintenance log — mandatory for commercial and industrial facilities subject to inspections.
- Ensure the valve's power supply is not interrupted during a general power outage — connect to a UPS-backed circuit in critical facilities.
- Never manually reopen the valve after an emergency closure before the leak source has been fully identified and repaired.
- For outdoor installations, periodically inspect the external housing to confirm IP65 rating integrity remains intact.

FAQ
Can the 3/4" valve be used on LPG lines, not just natural gas? Yes. The valve is designed to work with common gas types used in facilities. Verify the pressure specifications for your specific gas type against the 6-bar operating range to confirm compatibility.
What is the practical difference between a 1/2" and 3/4" valve in gas systems? The core difference is flow capacity. 3/4" allows significantly higher flow without causing pressure drops at consumption points — suited for main supply lines and high-consumption facilities. 1/2" is better suited for branch lines and light residential use.
Can the valve reopen automatically after closure, or does it require manual reset? This depends on the valve model and its wiring configuration with the detector. In professional safety applications, manual reset by a qualified technician — after verifying leak repair — is always recommended. Refer to the included operating manual for reset procedure details.
Can the valve be used on lines running continuously 24/7? Yes. Commercial and industrial-grade manufacturing means the valve is designed for continuous operation. It remains open under normal conditions and experiences mechanical load only upon closure events.
How do I verify my existing detector is compatible with this valve? The valve requires a standard control signal from the detector. Check the control output specifications of your existing detector and compare against the valve's control input requirements. If in doubt, contact technical support before purchasing.
Is IP65 sufficient for locations exposed to continuous water spray? IP65 covers full dust protection and water spray from all directions. For locations exposed to continuous spray or submersion, a higher rating (IP67 or IP68) may be required. For standard wet environments — commercial kitchens, boiler rooms, and locations exposed to light rainfall — IP65 is sufficient.
Does the valve stay closed during a power outage? Behavior during power loss depends on the valve's classification (normally open vs. normally closed). For safety-critical applications, a normally closed valve — which closes automatically upon power loss — is recommended as an additional safety measure. Refer to the detailed specifications or contact the sales team to confirm the correct specification for your application.
