General Description
Threaded Cartridge Style Counterbalance Valve.
Pilot assisted, designed for motion control
applications. For additional information see
Technical Tips on pages LM1-LM4.
Features
•
High flow design with extra dampening
•
Spring chamber isolated from system backpressure by
double seal, eliminating vent port leakage and need for
separate drain line
•
Poppet construction for minimal leakage
•
Incorporates direct acting relief valve for overload
protection
•
Includes reverse check valve within body, saving space
and minimizing installation cost
•
Hardened working parts for maximum durability
•
Adjustable and tamper resistant versions available
•
All external parts zinc plated
