Who We Are – Specialized Ball Valve Manufacturer
J-VALVES focuses on one product family and does it thoroughly: industrial ball valves. Our engineering team designs and manufactures floating, trunnion mounted, high-platform, metal-seated, fully welded, forged steel, DBB and three-way/four-way ball valves, in manual, pneumatic and electric actuated versions.
We serve projects where valve failure is not an option: oil & gas pipelines, FPSO and offshore platforms, LNG and cryogenic systems, seawater desalination plants, and EPC/OEM contracts. Each market has its own requirements book - NACE MR0175 sour service, fire-safe API 607, cryogenic extension bonnets, FBE coating for buried seawater lines - and our job is to match every requirement with the right valve, documents and test evidence.

Our Manufacturing Capabilities

Producing Department
The production department turns approved drawings into finished valves. From raw material procurement and CNC machining to assembly, pressure testing and final inspection, every batch moves through a documented process flow, and each valve carries its own serial number for full traceability.

Fully Welded Equipment
Our fully welded ball valve line is built around precision welding workstations that fuse body and connections with controlled heat input - giving trunk pipeline valves a leak-free, maintenance-free welded body from 2" up to 56".

Low-Temperature Laboratory
The low-temperature laboratory studies valve performance at -196°C and below, using liquid nitrogen and helium circulation systems with a controlled cooling box to test sealing performance, strength, fatigue life and material brittle transition of cryogenic ball valves for LNG service.

Pressure Testing Equipment
J-VALVES pressure test benches handle trunnion mounted ball valves up to 56" Class 900, 36" Class 1500 and 30" Class 2500, performing shell, seat and functional tests to API 598 and API 6D requirements on every production line.

Physical and Chemical Laboratory
Our physical & chemical laboratory verifies the chemical composition and mechanical properties of incoming materials, and applies PMI and heat-number traceability across the whole production process - the foundation of every material certificate we issue.

2D and 3D Design
The J-VALVES technical team provides full 2D & 3D design capability, from standard valve drawings to custom-engineered solutions for special service conditions, supporting EPC tender reviews and OEM private-label projects with fast drawing turnaround.

PRODUCTION SCOPE OF BALL VALVES
Our People – Engineering Training & Quality Culture
In today's highly competitive business environment, an efficient, collaborative, and innovative team is crucial to a company's success. The J-VALVES team building and training products have emerged as a response to this need. J-VALVES aim to help teams enhance their cohesion, communication skills, problem-solving abilities, and innovation capabilities through a series of carefully designed activities and courses, thereby facilitating the achievement of corporate goals.
J-VALVES Team Building
Friends, work is important indeed, but occasional indulgence and thorough relaxation are also essential. Why not have a villa party team building activity like ours and let the colorful activities liven up your team time!
Entrepreneur Sharing Session
We invest in people, not only machines. Regular sharing sessions with industry experts keep the team connected to real project requirements - from Shell and ADNOC specification practice to desalination plant material selection - so what we learn from projects flows directly back into our designs.
Ball Valve Technology Training
Every J-VALVES engineer and inspector goes through structured ball valve technology training: valve principles and classifications, seat and seal materials, cryogenic and fire-safe design logic, and test procedures to API 598 and API 6D. Internal training keeps our quotation answers technical, fast and consistent.

Christmas activities
On this special Christmas, the J-VALVES team got together with joy and
friendship. We exchanged carefully selected gifts, and each package was filled with anticipation and kindness. When opening the gifts, laughter filled the air, revealing the thoughtfulness within.
