Deposit water valve. An anti-cavitation structure with three multi-hole resistance plates. Natural gas valve. An angular body, pipeline counter flanges directly connected to the body. Working pressure 450 bar, nominal pressure PN700. Flow under the plug (FTO); full opening of the plug cuts off access of the agent and impact of pressure on valve stem packing. SPECIAL VALVES 23
Anti-cavitation valve. The body is made of a forging, threaded ends. A multi-step plug, and a throttling cage. Non-service packing of stem fulfilling tightness requirements according to TA Luft. It is currently in use at the “Dębno” gas mine in Poland. Cut-off valve. A flange body is made of forged X2CrNiMo17-12-2 (1.4404) – 316L. material Working pressure is up to 530 bar. Two-part plug structure: an internal plug and a main plug for static relief upon the opening of the valve.. Flow over the plug (FTC), high closure tightness. This product has been designed especially for the food industry. 24 SPECIAL VALVES
