VBA Booster Regulator

VBA pneumatic booster valves are power-free air amplifiers built on self-developed piston area difference boosting technology, delivering stable 2× and 4× pressure amplification with matched VBAT air tanks for instant high-pressure airflow. Fully pneumatic automatic cycling ensures explosion-proof & energy-saving performance, while built-in buffers cut noise and extend service life to over 50 million cycles with easy installation. We maintain sufficient stock of 5L-38L air tanks with growing annual sales. Widely adopted for cylinder clamping reinforcement, riveting, dispensing and mold high-pressure blowing, they offer a cost-effective local boosting alternative without upgrading whole plant air systems.

VBA Energy Saving Compact type Booster Regulator

Richge Technology compact energy-saving VBA pneumatic booster regulator adopts self-optimized high-efficiency boosting air circuit independent R&D technology, cutting air consumption effectively. The ultra-small lightweight body supports dual mounting ways with stable low-ripple high-precision pressure output. Fully pneumatic explosion-proof structure realizes maintenance-free long service life. We keep sufficient inventory and rising annual sales volume. Widely applied to auto manufacturing, automated clamping and mold cleaning, it offers economical local pressure boost without overall factory air system transformation.
