E-LOKC Pilot-to-close, spring-biased closed, unbalanced poppet logic element
SYMBOL
DESCRIPTION
The E-LOKC is a is a pilot-to-close, spring-biased closed, unbalanced poppet logic element.
OPERATION
These unbalanced, pilot-to-close logic valves are 2-way switching elements that are spring biased closed. Pressure at either work port 1 or 2 will oppose the spring and tend to open the valve while pressure at port 3 will tend to close it. The force generated at port 3, plus the spring force, must be greater than the sum of the forces acting at port 1 and port 2 for the valve to remain closed. NOTE: The pilot area (port 3) is 1.8 times the area at port 1 and 2.25 times the area at port 2.
FEATURES:
l These valves will work in standard T-19A cavity at lower capacity. To realize the full stated capacity, the T-19AU cavity should be used.
l Because these valves are unbalanced, operation is pressure dependent. Opening and closing of the poppet are functions of the force balances on three areas: Port 1 = 100%, Port 2 = 80%, and the Pilot Area = 180%.
l All ports will accept 5000 psi (350 bar).
