Wafer unidirectional knife gate valve is a TECTUL solution for shutting off sludge, slurry, water with solids, mining, treatment and discharge services where a conventional gate valve clogs. It is purchased by function, material, connection and compatibility, not only by physical similarity to another valve. The reported main material is iron, and the differentiating criterion is a wafer body and seal in one flow direction, with a knife blade that cuts through suspended material. This batch does not report a closed dimensional standard; therefore selection must be made with a technical data sheet, fluid, connection and actual operating conditions. For a useful quote, provide nominal size, quantity, fluid, service temperature if applicable, mounting orientation, actuation type and whether the line requires isolation, check, regulation, diversion or automation. This description avoids publishing generic maximum pressures because actual capacity depends on the complete design, seals, temperature and the code used by the project.
We dispatch to Bogotá, Medellín, Cali, Barranquilla and all of Colombia. Request a quote via WhatsApp for this wafer unidirectional knife gate valve, indicating size, quantity, fluid and connection to confirm availability and price.
The price depends on size, material, connection, quantity, availability and required accessories. At TECTUL we quote based on the fluid and the actual application.
The unidirectional valve seals in the specified direction; the bidirectional valve is selected when pressure or flow may come from both sides.
Orient the pressure side according to the data sheet, leave free travel for the knife and avoid installing it as a continuous regulating element.
Send size, quantity, fluid, connection, required material, standard if applicable, and a photo or drawing when replacing an existing valve.
No. Compatibility of the body, seals, gaskets and internal components with the fluid, temperature and line cleanliness must be validated.
Yes. TECTUL dispatches to Bogotá, Medellín, Cali, Barranquilla and other cities in Colombia depending on availability and carrier.
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.
