B Series Brass

If you are looking for versatility along with affordability and low maintenance, the B Series is for you.

This is the pneumatic control valve to choose for a wide variety of applications. In fact, the B Series can handle any task from vacuum to 200+ psi. 

The B Series is only one of three Versa product lines made of corrosion-resistant brass, one of the most durable alloys available for long-lasting performance in high temperatures. 

Key Features

Our B Series valves use a simple design allowing for the addition of a range of manual, pilot and mechanical actuator controls. This valve is based on Versa’s proven bubble-tight sealing technology and rated for air, oil or water.

  • Two-Way Types: Ideal for bleeding pilots of larger valves, for bleeding cylinders or small pressure systems, operating air tools or motors, opening or closing air lines
  • Three-Way Types: Ideal for controlling pilots or diaphragms of larger valves or small cylinders or any pressure system that is alternately pressurized and exhausted.
  • Pneumatic service: From vacuum to 200 psi (14 bar)
  • Hydraulic (two-way) service: Up to 500 psi (35 bar)
