Information about Jouka Oy

About us
Jouka Oy was established in 1957. We design and produce all our ball valves at our factory in Ylöjärvi in Finland with a personnel of about 40 people. In addition, we do metal pressings, machine parts and assembly as a subcontractor.

The ball valve is a pressure device
Valves were included under the European Pressure Equipment Directive (PED) in spring 2002. Every valve has its own serial number, which enables the tracking of the manufacturing process as well as the materials used.

Tailor-made valves
The aluminium valve is famous for its lightness and affordable price. It is also extremely easy to assemble and service. We use special materials according to the customer's wish. Valves can be made of stainless, acid-proof, Hastelloy or Duplex steel or plated with hard chromium.

Hundreds of possibilities
We make everything from manual to actuator valves, lockable ones, flow regulating valves and safety valves with a closing device.

Experienced and skilled
Jouka Oy has made ball valves for over 40 years and has used customer feedback to improve the product. That's why it lasts the longest.
