Logics valves – Normally Open

Logics Valve (LO) are unbalanced, pilot-to-close, logic valves. They are 2-way switching elements that are spring biased closed. How they work:

  • Pressure at either port 1 or 2 will oppose the spring and tend to open the valve while pressure at port 3 will tend to close it.
  • Operation is pressure dependent as valves are unbalanced.

Specifications of LO valves:

  • Rated flow of up to 760 LPM
  • Maximum pressure of 350 Bar
