SUN阀CWGALHN产品介绍
带先导辅助的通风平衡阀用于控制超负荷。止回阀允许从方向阀（端口 2）到负载（端口 1）的自由流动，而直接作用式先导辅助泄压阀控制从端口 1 到端口 2 的流量。端口 3 处的先导辅助以先导比确定的速率降低泄压阀的有效设定值。端口 2 处的背压不会影响阀门设定，因为弹簧腔参考通风口（端口 4）。
此阀门的其他名称包括运动控制阀和过中心阀。
• 平衡阀的设定压力应至少为最大负载诱导压力的1.3倍。
• 顺时针旋转调节装置可减少设定值并释放负载。
• 顺时针旋转设定为 200 psi (14 bar)。
• 所有 4 端口平衡阀、负载控制阀和先导开启止回阀芯在物理上均可互换（即，对于给定的框架尺寸，具有相同的流路、相同的腔体）。
• 当阀门为标准设置时，复位压力超过设定压力的 85%。低于标准设定压力的设置可能会导致复位百分比降低。
• 端口 4 处的压力以 1 加上先导比乘以压力的比率添加到有效泄压设定中。
• Sun 平衡筒可以直接安装到执行器外壳内加工的腔体中，以增加保护并提高电路的刚度。
• 该阀门所有端口之间均有正密封。
• 与非通风阀相比，通风阀可能需要较低的先导比来实现机器稳定性。
• 采用 Sun 浮动式结构，最大限度地减少由于安装扭矩过大和/或腔体/墨盒加工变化而导致内部零件卡住的可能性。
Vented counterbalance valves with pilot assist are meant to control an overrunning load. 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. Pilot assist at port 3 lowers the effective setting of the relief valve at a rate determined by the pilot ratio. Backpressure at port 2 does not affect the valve setting because the spring chamber references the vent (port 4).
Other names for this valve include motion control valve and over-center valve.
• Counterbalance valves should be set at least 1.3 times the maximum load induced pressure.
• Turn adjustment clockwise to decrease setting and release load.
• Full clockwise setting is 200 psi (14 bar).
• All 4-port counterbalance, load control, and pilot-to-open check cartridges are physically interchangeable (i.e. same flow path, same cavity for a given frame size).
• Reseat exceeds 85% of set pressure when the valve is standard set. Settings lower than the standard set pressure may result in lower reseat percentages.
• Pressure at port 4 is added to the effective relief setting at a rate of 1 plus the pilot ratio times the pressure.
• Sun counterbalance cartridges can be installed directly into a cavity machined in an actuator housing for added protection and improved stiffness in the circuit.
• This valve has positive seals between all ports.
• With vented valves, a lower pilot ratio may be required to achieve machine stability compared to non-vented valves.
