HASSASVALF: Your Solution Partner in Industrial Valve Engineering
Founded in 2008 in Kocaeli, the industrial capital of Turkey, HASSASVALF VANA MAKİNA SANAYİ TİC. LTD. ŞTİ. provides integrated maintenance, repair, and manufacturing services for high-pressure fluid control elements utilized in heavy industry, petrochemical, and energy facilities. With over 18 years of industrial valve experience, we continue our operations with an engineering-first approach and a guaranteed service mentality designed to minimize the downtime (shut-down) of your facilities.
Valve Maintenance, Repair, and In-Situ Machining
Your valves, which have lost their sealing properties due to exposure to corrosion, cavitation, or thermal fatigue, are restored to original factory tolerances by our expert engineering team using reverse engineering methods. Damages on the disc and seat surfaces are eliminated with specialized lapping technologies, ensuring maximum safety across your process lines.
- Comprehensive Overhaul: Detailed disassembly, sandblasting, precision machining, and assembly processes across gate, globe, ball, butterfly, and check valve groups.
- Certified Testing Procedures: Hydrostatic and pneumatic sealing tests in strict accordance with API 598, API 527, and EN 12266-1 standards for all repaired valves.
- Spare Parts Manufacturing: Rapid response to emergencies with the in-house production of flanges, fittings, stems, and gland packings complying with ASME and DIN norms.
- Project Design and Engineering: Industrial solutions based on occupational safety through system improvement projects, custom hydraulic cylinders, and specialized hydraulic valve designs.
Global Standard Supply and Sales Network
As of 2020, we have integrated the technical expertise gained from meeting the heavy repair needs of industrial facilities into our sales and procurement operations. We select the most suitable brand-new valves tailored to the corrosive nature of your process fluid, operating temperatures, and nominal pressure ratings (PN/Class) using an engineering-based approach. As both a manufacturer and supplier, we provide high-quality products at optimal costs while directly contributing to the uninterrupted operation of your enterprise through our rapid supply chain.

Frequently Asked Questions
What sealing tests do you apply for the valves you maintain and repair?
All our fully overhauled valves are subjected to hydrostatic and pneumatic tests based on their specific operating pressures in our test units, which are designed in accordance with API 598 and EN 12266-1 standards. They are subsequently certified and delivered with a strict zero-leakage tolerance.
Do you provide on-site valve repair or custom part manufacturing during emergency shut-downs?
Yes, we provide in-situ (on-site) machining support via our emergency response teams during planned or unplanned shut-downs at your facility. Additionally, we prevent production losses by manufacturing critical emergency spare parts, such as flanges, seats, and stems, on a 24/7 basis in our own machining park.
Which industrial sectors do you serve regarding valve sales?
Since 2020, we have been supplying brand-new Gate, Globe, Ball, and Butterfly valves strictly for heavy industry, petrochemical plants, and large-scale water lines. Our process engineers carefully evaluate your fluid type and pressure class (ASME/DIN) to select and supply the most durable and appropriate product.
