DOROT 28-200, is a 2-way, Hydraulically-operated, Diaphragm-actuated Normally Open Relay Valve, designed to meet the requirements of hydraulic valve control functions; particularly when a quick reaction is required.
Operation principle
The Hydraulic Accelerator body contains one seat, a fully supported frictionless diaphragm and a guide shaft. When a pressure command is applied above the diaphragm, the disc forms a drip-tight seal with the valve seat.
