Advantages Of GEKO Pneumatic Gauge Valves

Large flux, low resistance, no water- hammer

Y-type angle valve enlarged the flawing section, which could raise the flux by 31% and make the flow more smooth.

Super long life

Which helps the stem adjust and lubricate itself automatically.

The cylinder materials stainless steel lubricating automatically and 360° rolling freely.
