OSI145 - Overcentre Valve (180 lpm)

Application

Overcentre valves give static and dynamic control of loads by regulating flow into and out of hydraulic actuators. The Overcentre valve will stop the load from running away in the event of a hose burst. If open centre directional control valves are used, they will allow the thermal expansion relief of the hydraulic fluid. These valves provide excellent hose burst protection.

Operation
The check section allows free flow into the actuator then holds and locks the load against movement. The pilot pressure in the pilot port will give a controlled movement to piston when the pressure is applied. The pressure required to open the valve and allow movement depends on the pilot ratio of the valve.

Double Lock Check Valve (DLCV 3W)

Tucson is proud to introduce their latest addition to the Check and Pilot Check Valve range, the "Double Lock Check Valve". Tucson has maintained the fit, form and function of the valve to correspond with industry standard products to ensure easy of replacement and zero cost to system designers looking for a better and more stable solution for locking cylinders.

The valve is characterized by its robust and compact design and is highly reliable in the field. The valve provides some new features over the current industry common product

• Hardened Poppet-Seat assembly provides a metal-on-metal sealing on the check valve which prevents leaks even after abusive cycling
• Hardened and ground pilot pistons prevent wear on the land over long periods of time preventing cross port leakage
• PTFE Energized sealing on the poppet provides a superior seal between Valve and Pilot Ports
• All cartridge components are manufactured in STEEL to ensure robustness in function.
• Body material is 6351 T6 Aluminium to keep weight to the minimum
• Mounting Dimensions have been maintained for ease of installation

Sun-fit Valves

Application

Overcentre valves give static and dynamic control of loads by regulating flow into and out of hydraulic actuators. The Overcentre valve will stop the load from running away in the event of a hose burst. If open centre directional control valves are used, they will allow the thermal expansion relief of the hydraulic fluid. These valves provide excellent hose burst protection.

The following valves are Sun-fit valves that fit into Sun Cavities T-11A and T-2A

The following list contains valves from Tucson that are not Sun-fit valves, but perform the same functions
