PRE-ORDER : 4-6 WORKING WEEKS

Description

LF691

Low-Flow Hydraulic Pressure Regulator: Liquid / Piston / Ceramic Seat / Non- or Self-Venting / Max. Inlet: 1,380 bar (20,000 psi) / Max. Outlet: 1,380 bar (20,000 psi) / Cv 0.05, 0.1 or 0.3

The LF691 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 LF691 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.

 

FEATURES:

• Ceramic seat design
• Fully supported main valve
• Segregated captured vent
• Easy access to seat cartridge
