Description

Cast gate valve URPS BIRS B10

These valves are designed to operate on pressures (PN) up to 4.0 MPA, with a conditional pass diameter (DN) of 15 mm -250 mm. In large pipeline diameters and having small expenditures, it is cost-effective to mount a smaller valve; in such case the valve design involves the application of flanges of frame body, the grooves of which are in the form of truncated cones with diameter of internal base equal to the conditional diameter of the valve, and of outside- equal to the demanded pipe diameter (so-called diffusers and confusors). This allows, for example, to use DN100 mm diameter valve on pipline with diameter of 300 mm.

A peculiarity of valves URPS BIRS B10 design is production of such valves from high-quality steel by casting into gasified models. Input instrumental control of raw materials allows to obtain ensured stable indicators at the process beginning. Non-destructive testing of cast blanks ensures absence of leaks on the frame body during the warranty period of the product.

Valve counterpart is adapted for the application of various control means for linear electric power actuators BIRS 14 and diaphragm pneumatic actuators BIRS 37.

Valves URPS BIRS B10 meet the requirements of State Standard TR TC 012. The product is assigned the category IIGbcT4.
