Design features of valve VK-20 DONMET:
1) drainage hole;
2) double sealing providing high reliability;
3) direct contact of spindle and valve;
4) increased thread diameter improves durability;
5) use of oxygen-resistant lubricant.
The valve is to be installed at the gas cylinder. The pressure regulator is connected to the valve. When turning the knob, the valve goes up and opens the gas supply with maximum working pressure up to 20 MPa. Increased valve thread diameter and oxygen-resistant lubricant ensure 10000 open/close cycles before conducting the first repair.
100% of valves VK-20 DONMET pass trials under hydraulic pressure of 30MPa which guarantees your safety.
