The HYD 690 is the compact version of the highly successful LF-690 series regulator, it has been designed as an economical alternative to the LF-690, yet still incorporates all the key features of the larger regulator. The Tungsten carbide main valve and 17-4PH SS seat provide ultimate protection against the harsh service encountered on hydraulic services and can now be easily serviced from the spring section. The regulator is self relieving with a segregated captured vent as standard.
