The DirectAir 2 valve is a compact designed manual or mechanical operated Inline valve. The variety of operators include roller, lever, push button, plunger and one-way tripper operated valves. The roller, plunger, one-way trippers and toggle valves are ideal for space saving mounting to provide cylinder positioning feedback. The valve design features both spool and poppet type valves. The spool valves have balanced forces across the spool so that 3/2 valves can be piped normally open or normally closed by changing the inlet supply from port 1 to port 3. DirectAir valve bodies are manufactured from aluminum with stainless steel spool, sealed by static fluorocarbon seals.
