The new series of high-pressure valves from Maximator is compact but offers nominal diameters up to 1 inch. The valves in the ValvolutionX series are also said to weigh only a quarter of previous models. The comparison refers to “conventional, pneumatically operated high-pressure needle valves,” according to Maximator. The issue with pneumatic needle valves: at high pressure and large diameters, a great deal of force is required to operate them. This necessitates larger pneumatic actuators – and therefore more space.
Maximator now relies on a new “cartridge technology.” This allows the size of the pneumatic actuator for shut-off and venting in high-pressure applications with hydrogen and inert gases up to 1,050 bar to be reduced to a diameter of 3 inches. The valves are suitable for connections with nominal diameters from 9/16 to 1 inch. The number of valve components has also been reduced – making the valves lighter. The amount of compressed air required is said to be reduced by up to 90%, allowing for a smaller compressed air supply for the entire system. The valves are bidirectional and can therefore also be used for testing applications.
Maintenance time is expected to be reduced by 60%, as the valves can be serviced in situ within minutes with just a few simple steps, using only two maintenance kits regardless of size. According to Maximator, the sealing elements last for 20,000 cycles – significantly more than the 16,000 required by standards. To safely direct potential leaks away from the system environment, the ValvolutionX series is equipped with separate connections for leak piping. Application areas include, for example, refueling of buses and trucks.
