The Nitra pneumatics line includes two additional series of valves and manifolds. The BVS-3 series modular solenoid valves are body-ported three-port (three-way) poppet valves available in two-position, normally open or normally closed configurations. The BVS-4 series modular solenoid valves are two-position, single-spring return, body-ported four-port (four-way) spool valve models. BVM series manifolds help to simplify the mounting and wiring of BVS series solenoid valves. Made of sturdy glass-reinforced thermoplastic with DIN rail mounting clips included, they feature push-to-connect air connections for quick tubing installation. Control distribution blocks also are available for BVS-4/BVM-4 assemblies. Additional accessories include replacement solenoid coils, aluminum manifolds and blanking plugs.
