Engineered for Flow.
Built for Industry.

Corvalve manufactures a broad range of pipeline components, including butterfly valves (lug, wafer, and double eccentric), gate valves (metal seated, resilient seated, and rising stem), check valves (silent/non-return, swing, and tilting), air valves (single and double chamber configurations, including non-slam, vacuum, underground, and sewage types), dismantling joints, basket type strainers, and duckbill check valves. Material and configuration vary by product type and size.

Corvalve products are designed and manufactured in accordance with recognized international standards, depending on the product line and configuration. Common references include EN 558 (face-to-face dimensions) and, for resilient seated gate valves, EN 1171, with testing outlined in EN 1074-2. Where applicable, different flange drilling patterns may be available, including ISO, EN, and ANSI.

Corvalve offers a wide selection of DN and PN ranges across its valve and pipeline component portfolio—lug/wafer butterfly valves DN40–DN300 (PN16), double eccentric butterfly valves DN100–DN2500, swing check valves DN40–DN1000, non-return check valves DN50–DN1000, air valves DN25–DN500, dismantling joints DN80–DN2200, and basket strainers DN100–DN1600; for the best-fit selection and quotation, share your required DN, PN, service media, operating temperature, and flange drilling pattern.

Corvalve products are widely used in water transmission and distribution, water and wastewater treatment, sewage networks, irrigation, and general pipeline applications; suitability for potable water versus sewage service depends on the selected configuration and specified materials, seals, and coatings.

Corvalve exports to 85+ countries worldwide from Istanbul, Türkiye, supporting international projects with end-to-end export coordination—including documentation, packing, and shipment planning—for destinations across Europe, the Middle East, Africa, Asia, and the Americas. Contact our export team to confirm lead time, Incoterms, and delivered pricing for your location.

Selection depends on the application duty and performance requirements. Lug and wafer butterfly valves are commonly used for standard on/off isolation, while double eccentric butterfly valves are preferred for larger sizes and applications requiring reduced operating torque. For check valves, swing types are typically chosen for general backflow prevention, while non-return (silent) types are used where faster closure and reduced water hammer risk are priorities.

Installation orientation depends on the product type. Some models are suitable for both horizontal and vertical installation (e.g., swing check valves per the datasheet), while other products may have standard installation requirements depending on configuration and size. For best results, confirm orientation and installation notes during selection.

Options vary by product line and size. Typical options include gearbox and actuator (available for gate valves), bypass valves for large sizes, limit switches for SCADA monitoring (common on air valve configurations), and multiple coating systems, including potable-water certified coatings and fusion bonded epoxy.

To quote accurately, please provide the required DN (size), PN (pressure rating), service media (e.g., potable water, wastewater), operating temperature, flange drilling pattern (ISO/EN/ANSI), and any required coating or accessories (e.g., gearbox/actuator, limit switch).
