Valves of PEK 000.040 (41;42) type are used in the equipment of CNG filling stations as shut-off elements of the processing lines, and more often as valves for pressure gauge connection.

• Nominal pressure Pu = 25 MPa.
• Nominal diameter Du = 4 mm.
• Input and output connecting threads – M16x1.5

Depending on the design of the input threaded fitting the valves of PEK type have the following designations: 040; 041; 042.
