Dual, direct-acting relief valve - pilot capacity
Cavity: T-11A | Capacity:
Technical specifications
This direct-acting, pilot relief cartridge incorporates back-to-back check valves. This allows it to remotely control 2 other pilot-operated valves or act as a thermal relief for both ends of an actuator. Because capacity is limited to pilot flow, this valve should be used with other valves with comparable pilot flows.
- The back-to-back check valves prevent cross talk between the two valves that are being remote controlled.
- One adjustment controls two valves.
- Check cracking pressure is 15 psi (1 bar).
- Pressure at port 3 is directly additive to the valve setting.
- Suitable for load holding applications
- The term thermal relief means it prevents overpressure due to thermal expansion of the fluid.
- Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.
