SUN阀CBCGLJN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*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。

• 顺时针旋转设定值小于 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。

• Sun 平衡阀芯可以直接安装到执行器外壳中加工的腔体中，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。

• 此阀在先导部分没有正向密封，在端口 2 和端口 3 之间将以高达 3 in³/min.@1000 psi (45 ml/min.@70 bar) 的速度通过。这是主从电路和阀缸组件泄漏测试中的考虑因素。

• 配置有 EPDM 密封件的阀芯用于磷酸酯流体系统。接触石油基流体、油脂和润滑剂会损坏密封件。

• 所有 3 端口平衡阀、负载控制阀和先导开启止回阀阀芯在物理上均可互换（即，对于给定的框架尺寸，流路相同、腔体相同）。

• 耐腐蚀筒式阀适用于腐蚀性环境，其型号代码后缀为 /AP（外部不锈钢组件）或 /LH（外部镀锌镍组件）。

• 采用 Sun 浮动式结构，以*大限度地减少由于安装扭矩过大和/或腔体/筒式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.

• 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 does not have positive seals on the pilot section and will pass up to 3 in³/min.@1000 psi (45 ml/min.@70 bar ) between port 2 and port 3. This is a consideration in master-slave circuits and in the leak testing of valve-cylinder assemblies.

• 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.

• 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).

• Corrosion-resistant cartridge valves are intended for use in corrosive environments and are identified by the model code suffix /AP for external stainless steel components, or /LH for external zinc-nickel plated components.

• 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.
