The main activities in the production ot WATO are:


Development of new and optimization of existing products

In the company's testing and development activities is used SolidWorks mechanical engineering software, with a complete set of tools for 3D design, research, data management and communication.


Machining (drilling, turning, threading, milling)

Various types of metal cutting machines are used for the various machining operations of the parts - straightening machines, drilling machines, universal and program lathes and milling machines.


Application of varnish-paint coatings (cold painting)

The coatings are applied by hand or using a pneumatic gun.


Applying epoxy powder coating (hot painting)

For high quality coatings, metal parts for painting are pre-shot blasted. The technology utilizes a fluidized bath to immerse the parts after preheating. This method of applying the coating is much more efficient and quality compared to electrostatic painting with a gun.


Application of rubber coatings (gumming) and production of rubber gaskets

WATO's Vulcanizing Press ПХВ-60 has a 1000x1000mm heating plate size.


Manufacture of plastic parts

The new high-performance injection molding machine HAITIAN MA4700 II has a maximum injection volume of 1860 cm3 (1,693 kg polystyrene).



Manual process using high performance equipment and control devices.


Hydromechanical tests of finished products

Each stopcock is hydraulically tested with specialized hydraulic stands. Maximum torque (МОТ) and minimum torque (mST) control is performed using torque wrenches.


Packaging, storage and shipping

The ready-to-ship production is packaged on europallets with ECOSPIR ELC / AX packing machine.

Additional activities in the production:

  • Workpiece machining of parts by drawing or sample of the client.
  • Production of threaded rods and parts with external threaded section by forming the thread of a threaded machine. Machined diameter from 4mm to 250mm. Thread types: metric, inch, trapezoidal with maximum thread pitch of 8mm. Forming force - from 10 to 600 kN (60t).
  • Production of plastic parts with or without the tool from the customer. Spray machine characteristics: Maximum injection volume - 1860 cm3 (1,693 kg polystyrene). Locking force - 4700 kN (470t). Intercooler spacing - 820x800mm and size of the heating plates 820х800mm. Instrument height - 320mm.
  • Application of rubber coatings on metal products. Manufacture of rubber seals up to 900x900x250mm.
