This system is shorter and lighter than its siblings, and has a lower air consumption (smaller pneumatic actuators on request to be compared with the electric or pneumatic ones provided).
This valve has PTFE V-ring sealing units and EPDM linings, that extends lifetime, an enhanced handling with the upper part that can be rotated by 360°. The shaft guiding promises that, even at high differential pressures, no vibrations occur. This valve can be used in presence of brine, warm water, hot water, refrigerant, steam, gas, and other fluids.
