PRESSURE TECH LF691 Pressure Regulator is a piston-sensed low-flow reducing regulator with ceramic seating to provide the ultimate protection against the harsh service encountered on water-based hydraulic applications such as water glycol. In addition, the LF691 offers a plug design for supply above 690 bar (10,000 psi). Its unique seating cartridge ensures the main valve is fully supported during operation to prevent ‘chattering’. The PRESSURE TECH LF691 Pressure Regulator is supplied with a segregated captured vent to prevent deterioration to the loading mechanism and allowing media to be piped off to the return tank.
