'Assembly drawing for reference only. Refer to office for specific detail.

The LF-690 uses a Tungsten Carbide main valve and 17-4PH SS seat to provide ultimate protection against the harsh service encountered on hydraulic services. The unique seating cartridge provides a dampening action on this critical component to prevent 'chattering' or 'unstable frequency resonance'. The regulator is self relieving with segregated captured vent to prevent deterioration to the loading mechanism and making the regulator cleaner to service. The seating area can easily be accessed from the base of the regulator for speedy servicing in situ.

APPLICATIONS:

• Wellhead logic and control systems

• Subsea valve actuator control

• Valve test rigs

• Liquid sampling

• Hydraulic Power Packs

FEATURES:

690bar/10,000psi inlet pressure

elements. 3 Sensor ranges for combination of low torque and

high sensitivity. Segregated captured vent

316SS Panel mounting rings
