Globe valve A110 series

for LPGdifferential-action

The A110 Differential Pressure Control Automatic Control Valve controls the pressure difference between two points in a system. It has a wide range of applications: anywhere an increase in the sensed pressure differential causes the valve to open. The normally closed, spring-loaded pilot, sensing two pressure points, responds to changes in the pressure difference and causes the main valve to do the same. The valve opens on increased differential. The net result is a constant modulating action of the pilot and main valve to hold the pressure differential constant. The pilot system is equipped with a needle valve response speed control that fine tunes the valve response to the system variables. The high pressure sensing point is typically at the valve inlet, while the low pressure sensing point can be valve outlet or remotely connected, e.g., pump suction.
