The supervised grooved butterfly valve is a control valve for fire protection networks that combines grooved ends, a ductile iron body and a supervisory device to indicate open or closed position to the monitoring system. It is used in risers, pump rooms, main branches and zones where the design requires fast sectioning with visual and electrical confirmation. Unlike a grooved butterfly valve with handwheel and no supervision, this version incorporates signaling to reduce the risk of leaving a line closed without warning. In PCI projects, selection must review diameter, grooved connection type, coupling compatibility, UL/FM listing, panel requirements and accessibility for operation. It should not be chosen only by price: a poorly specified control valve can affect testing, maintenance and system availability.
We dispatch to Bogotá, Medellín, Cali, Barranquilla and all of Colombia. Request a quote via WhatsApp for your supervised grooved butterfly valve indicating diameter, quantity and UL/FM requirements.
The price depends on diameter, UL/FM approval, supervision type, availability and quantity. TECTUL quotes per unit.
The supervised valve includes a position signal for monitoring. The handwheel valve without supervision only allows manual operation and local visual verification.
It is mounted with compatible grooved couplings, left accessible and the supervisory switch is connected to the alarm or monitoring system.
In fire protection networks, control valves usually remain open except during testing or maintenance procedures authorized by the system manager.
Diameter, quantity, city, whether UL/FM is required, required supervision voltage or contact and use location in the network.
Orientation must follow the manufacturer's instructions, operator access and protection of the supervisory mechanism.
Before using these data in engineering decisions — design, installation or systems with mechanical risk of pressure, rupture, fatigue, impact or water hammer — you must read the Technical notice and limitation of liability at the end of this page.

The dimensions, thicknesses, pressures, temperatures and other characteristics stated in this data sheet are theoretical nominal reference values, compiled from publicly available technical sources: international standards (ASME, ASTM, API, MSS, ISO and NTC, depending on the product) and published engineering literature. They are average approximations intended to guide selection, not a certificate of conformity for any given lot.
Actual values may vary due to conditions inherent to the manufacturing process — dimensional and wall-thickness tolerances (in pipe, typically ±12.5%), surface finish and residual stresses from forming or welding — and to factors inherent to the raw material — chemical composition variations within the ranges allowed by the standard, inclusions or heat-to-heat differences. They may also be affected by in-service events not foreseeable at design time: water hammer, vibration, thermal and mechanical fatigue, corrosion and operating overpressures, which can cause the element to fail before its estimated service life.
To know the certified behavior of a specific lot, TECTUL supplies upon request the manufacturer's mill test certificate (MTC) issued per the product standard; for critical applications, laboratory testing of the lot can also be arranged. In the absence of such certification, the data provided here must not be used as the sole criterion in critical or safety applications, or wherever the integrity of the line may compromise the lives of people or property; in such cases, consult our technical team first.
