SUN阀CBGALAN产品介绍
带先导辅助装置的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 处的先导辅助装置以先导比确定的速率降低泄压阀的有效设定值。
• 平衡阀的设定值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以降低设定值并释放负载。
• 顺时针全程设定值小于 200 psi (14 bar)。
• 端口 2 处的背压以 1 加上先导比乘以背压的比率增加到有效泄压设定值。
• 当阀门为标准设定时，复位超过设定压力的 85%。低于标准设定压力的设定可能导致复位百分比降低。
• 配置有 EPDM 密封件的阀芯用于磷酸酯流体系统。接触石油基液体、油脂和润滑剂会损坏密封件。
• Sun 平衡阀芯可直接安装到执行器外壳加工的腔体中，以增加保护并提高回路的刚度。
• 提供两种止回阀开启压力。除非担心执行器气蚀，否则请使用 25 psi (1.7 bar) 止回阀。
• 此阀的所有端口之间都有正密封。
• 所有 3 端口平衡阀芯、负载控制阀芯和先导开启止回阀芯在物理上都是可互换的（即，对于给定的框架尺寸，流路相同、腔体相同）。
• 采用 Sun 浮动式结构，以最大限度地减少由于安装扭矩过大和/或腔体/阀芯加工变化而导致内部零件卡住的可能性。
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.
• 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 less than 200 psi (14 bar).
• Backpressure at port 2 adds to the effective relief setting at a ratio of 1 plus the pilot ratio times the backpressure.
• 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.
• Cartridges configured with EPDM seals are for use in systems with phosphate ester fluids. Exposure to petroleum based fluids, greases and lubricants will damage the seals.
• Sun counterbalance cartridges can be installed directly into a cavity machined in an actuator housing for added protection and improved stiffness in the circuit.
• Two check valve cracking pressures are available. Use the 25 psi (1,7 bar) check unless actuator cavitation is a concern.
• This valve has positive seals between all ports.
• All 3-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).
• 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.
