Surge anticipating relief valve is a TECTUL product for discharging transient overpressures in pumping stations and long pipelines when a pump stops. It is distinguished by anticipated opening on pressure drop and relief of the return wave, so it should not be purchased only by diameter or by similarity to another valve in the family. The reported main material is ductile iron. This lot has no scraped sizes or closed dimensional standard; therefore selection must be made with the data sheet, fluid, connection, orientation and actual operating conditions. For an accurate quotation, it is advisable to provide nominal size, quantity, fluid, temperature if applicable, connection type, mounting orientation and expected function: shutoff, check, relief, control, blowdown or regulation. We do not publish one single maximum pressure because capacity depends on the complete design, material, seals, temperature, water hammer, installation and project code.
We dispatch to Bogotá, Medellín, Cali, Barranquilla and all of Colombia. Request a quote via WhatsApp for this surge anticipating relief valve indicating size, quantity, fluid, connection and use 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 actual application.
The anti-surge check valve prevents backflow at discharge; the anticipating valve relieves pressure toward discharge or controlled return. They are complementary, not equivalent.
Install it on the branch defined by calculation, with safe discharge, accessible pilots and functional start and stop tests.
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.
