The union flow control valve for pneumatic tubing is used in pneumatic circuits to shut off, select, or regulate air flow in tubing, actuators, panels, and machines. Purchasing should start from the tube outside diameter, thread or connection type, circuit function, and compressed air quality. It differs from hydraulic or water valves because its internal passages, actuation, and connections are designed for air and instrumentation. TECTUL separates needle, union, shutoff, and knob valves to avoid confusing fine regulation with simple opening and closing.

We dispatch union flow control valve for pneumatic tubing to Bogotá, Medellín, Cali, Barranquilla, and all of Colombia. Request a quote via WhatsApp with size, line material, fluid, quantity, and actual operating conditions to confirm compatibility before purchasing.
The price depends on size, material, connection, and availability. TECTUL quotes per unit using the actual application data.
It may be a shutoff, needle, regulating union, or selector knob valve. The circuit function defines which one applies.
It is installed with the compatible connection, respecting flow direction or component orientation and without transferring pipe loads to the body.
Send size, required material, fluid, connection type, quantity, dispatch city, and known operating conditions.
It depends on the material in contact with the fluid and the project's sanitary requirements. TECTUL validates compatibility before dispatch.
Yes. TECTUL dispatches to Medellín, Cali, Barranquilla, and intermediate cities through a carrier or coordinated pickup.

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.
