Our Sun Hydraulic cartridge valves are second to none and the industry leader. Often used to extend and then retract a cylinder at different speeds, they create two actions and have two exhaust ports, which allows you to control the speed of each action by attaching a flow control valve to each exhaust port. For this purpose they are pre-loaded with a pressure setting that is higher than the largest possible load. But, direct flow is not possible because of the blocked spool valve(4) under the action of spring force(3). #8 Spool – Tandem Spool. Type VABAL counterbalance valves • Cross line, relief valve for motion control • Load sensitive Technical specifications and diagrams are measured with mineral oil of 46 cSt viscosity at 40°C (104°F) temperature. Counterbalance valves Standard poppet type differential area, counterclockwise adj. from verified sources and present in 60 words shorts. Even under the inoperable conditions, these valves will hold the load firmly against the gravitational force by applying a back pressure against the load. While counterbalance valves maintain a healthy amount of back pressure, they force the pump to develop the full set pressure on the counterbalance spring before they allow the actuator to move. The check valve allows free flow from the directional valve (port 2) to the load (port 1) while a direct-acting, pilot-assisted relief valve controls flow from port 1 to port 2. 444. Load-holding valves, also known as over-center valves or counterbalance valves are a type of pressure control valve. 1-2 What counterbalance valves are used for.
