COUNTERBALANCE VALVES - Bosch Rexroth
apps.boschrexroth.comthe relief opening and the piloted opening are independent from back-pressure at port V2. Venting is often open to atmosphere and, whenever possible, is connected to tank or to a low pressure line. They must be used only in conjunction with main control valves having closed centre spools and equipped with port relief valves.
Trunnion-mounted Ball Valves
www.lntvalves.comL&T Trunnion-mounted Ball Valves are also offered with Double Piston seats. In this design, cavity pressure acts on both upstream and downstream seats to create a ‘double piston’ effect on seat rings that enhances sealing. Valves with Double Piston seats require an external cavity relief mechanism while handling non-compressible fluids.
