Valve RVIALCNCKBB-XCN pilot open one-way valve with external interface balance valve DTBF-MHN-224 and standard pilot flow valve: 30L/min| Hole type: T-163A CKCB-XCN pilot open one-way valve with standard pilot flow valve: 60L/min| Hole type: T-11A CKEB-XCN pilot open one-way valve with standard pilot flow valve: 120L/min| Hole type: T-2A CKGB-XCN pilot open one-way valve with standard pilot flow valve: 240L/min| Hole type: T-17A CKIB-XCN pilot open one-way valve with standard pilot flow valve: 480L/min| Hole type: T-19A The balance valve is used to control the overload. It allows oil to flow freely in one direction from the directional valve (port 2) to the load port (port 1), while the direct acting, pilot assisted overflow valve function can control the fluid flow from port 1 to port 2. The pilot assistance of port 3 reduces the effective set value of the overflow function with the coefficient of action of the pilot ratio. Due to the atmospheric connection of the spring chamber, the back pressure of port 2 will not affect the set value of the valve. This valve is also known as a motion control valve or a bypass center valve. Generally, hydraulic elevators do not have counterweight devices, which can improve the utilization rate of shaft area The setting value of the balance valve should be at least 1.3 times the load pressure value. Pilot switching direction valve DTBF-MHN-224 valve RVIALCN Turning the adjustment clockwise will decrease the setting and decrease the pressure. Under complete pressure relief, set to 200psi (14bar).

Approximately every 4000 cycles will produce 1 drop (0.07cc) of leakage from the pilot area flow spring chamber.
Under standard settings, the reset pressure value of the valve is 85% higher than the valve opening value. When the set value is less than the standard set value, the * * * ratio of the reset pressure value will correspondingly decrease.
Sun's balance valve can be installed into the installation hole inside the actuator, becoming a part of the actuator, thereby more safely protecting the circuit.
This valve is completely sealed between all ports.
Compared with machines without external leakage, for the smooth operation of * * * machines, the external leakage valve can use * * * pilot ratio * * machines.
The 3-port external relief valve is an atmospheric balanced valve, which is a solution to some existing problems (incorrect use of a pilotless relief valve). This type of valve can cause leakage after prolonged use, and the spring chamber is also prone to moisture. So, for the new solution, we use a four port pilot oil relief valve.
