PressureTech2000 LF-690 Hydraulic Regulator

Hydraulic Service Pressure Regulators - Models LF-690/LF-691

Features:

	High-pressure hydraulic regulators
	Main valve capacity Cv 0.1
	Maximum 1035 bar inlet
	Up to 690 bar outlet
	Captured segregated vent
	Easily accessible seat and main valve cartridge
	Fully supported sensing piston
	Load bearings to minimize hand wheel torque, and provide easy adjustment
	Tungsten Carbide main valve and 17-4 ph seat for ultimate resistance against hydraulic erosion and cavitation
	NPT or Autoclave porting
	Stainless Steel bonnet as standard
	Low torque spring adjustment or ratio air loaded options.

The LF-690 pressure regulator incorporates metal to metal seating to withstand the harsh service encountered in hydraulic pressure control. The unique seating cartridge provides a dampening action to the main valve to prevent "chattering" or "unstable frequency resonance". The regulator is self-relieving as standard, with segregated captured venting to prevent deterioration to the loading mechanism and making the regulator cleaner to services. The seating area can be easily accessed from the bottom of the regulator for speedy servicing in-situ.

Applications:

	Wellhead logic and control systems
