Info

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
Anti-cavitation valve. This product solves the problem of regulation and anti-cavitation protection at small opening of the valve. The internal plug – multi-step, the main plug – two-step, with a throttling cage in the seat. Flow over the plug (FTC). Double-position anti-cavitation valve. This product solves the problem of small flows during big pressure reductions and big flows at small pressure reductions, if there is a risk of cavitation in both cases. A three-step profile/piston plug, a throttling cage divided into chambers with proper throttling. SPECIAL VALVES 25
